A '''beholder''' is a giant lumpy... thing that looks like a floating octopus with a giant eye in the middle. The tentacles also have eyes at the end of them. Yuck.

Beholders, like [[Illithid|Mind Flayer]]s, are considered "intellectual property" of <s>TSR</s> Wizards of the Coast, so they aren't allowed to be used in third party D&D supplements or in [[Pathfinder]] as they were not covered under the [[OGL|Open Gaming License]]. This naturally doesn't stop [[ChapterHouse Studios|weirdly]] [[Original character, do not steal|similar]] creatures from appearing in various [[weeaboo]] JRPGs and related works, where they're usually called "gazers" or similar. Yes, this includes [[Monstergirls]]. Of course one game even used the name beholder, but we all excuse it, because this game is [[Heroes of Might and Magic|THE GAME. THE LEGEND.]]

The Beholder first appeared on the cover of the [[Greyhawk]] supplement for the Original Dungeons and Dragons. The creation of [[Spelljammer]] where beholders play an major role resulted in the creation of many varieties of beholders. Much information about their biology and culture was revealed in the book [[Lords of Madness]]. They also got an entire book to themselves in second edition called ''I, Tyrant''.

==Personality and Characteristics==

Beholders are selfish bastards who love to manipulate and enslave any races considered beneath themselves (i.e. every other species). They are extremely [[Imperium|xenophobic]] even going so far as to kill other individuals of their species that look even ''slightly'' different from themselves, though they always go after the more extreme divergences first; two beholders will gang up on the "freak" with scales and fiery eyes before trying to kill each other over the differences in their numbers of teeth. Soooo basically the D&D equivalent of a [[Doctor Who|Dalek]]. Even if two beholders look identical to each other they will struggle to cooperate with each other due to their extreme paranoia. Large groups of beholders can only work together while under the mind control of a beholder hive mother or an overseer.

Despite this, or perhaps because of it, the beholder race has a lot of genetic variety (as evidenced by the number of Beholder variants, all of whom hate each other, as listed below). They are greedy, often living in dungeons stuffed with valuables. They can cast magic from their eyes and often rule over unwilling souls through domination. One even runs the Thieves' Guild of Skullport, the most recent of several beholders to have done so.

Beholders worship the [[Great Mother]] and due to their massive egos, each beholder is convinced that not only does the Great Mother look exactly like itself, but also that it's ''literally'' their mother (false memories are funny like that). Beholders would be shocked and possibly driven mad (or madder than they already are) if they found out that the Great Mother, despite possessing vast knowledge, is completely insane and acts mainly on instinct instead of logic, unlike her children. Beholders also have another god named [[Gzemnid]] who is associated with gases and deception. Worshipers of Gzemnid are considered [[Heresy|heretics]] by other beholders because they believe that the Great Mother is actually constantly changing in appearance and creates different breeds of beholders every time she reproduces so there is no master race of beholder.

Part of the reason why beholders are so egotistical and paranoid is because they actually possess two minds. They do most of their thinking with their rational mind, but they also possess an intuitive mind which can censor the beholder from experiencing anything that might threaten their ego. This causes the beholder's rational mind to have no memory of times when they failed at anything, and to try to explain the missing memories with conspiracy theories.

Like [[Aboleth]]s, when a beholder is born, they inherent memories from their parent, though not a complete set of memories. This is why trying to raise a baby beholder to be good is a terrible idea, as their xenophobic beliefs are one of the things they inherent.

While good beholder technically are possible, they are extremely rare because turning good requires a beholder to give up on everything they have ever believed since birth, which by beholder standards would make them insane even compared to other insane beholders. Even beholders that are tolerant enough of non-beholders to work with them are usually still evil and tend to become crime bosses.

A standard beholder has a roughly spherical body with no distinction between their head and torso. Their skin comes in a wide variety of colors and textures. They have large mouth full of sharp teeth and a single central eye that constantly projects an anti-magic cone when it is open. At the top of their head are ten stalks tipped with smaller eyes. In some beholder breeds the eye stalks resemble tentacles while in others they are jointed. Each of theses eyes can fire a magical ray at will, with each eye having a different ray. Theses rays are: Charm Person, Charm Monster, Sleep, Telekinesis, Flesh to Stone, Disintegrate, Fear, Slow, Cause Serious Wounds, and Death. They have no other appendages besides these eye stalks. A beholder can levitate and fly. This ability is not magical in nature as it isn't affected by anti-magic fields or else beholders would knock each other out of the air by looking at one another. Beholders with significant deviations from this form are known as Beholderkin. Beholderkin may be born randomly from beholders, and are usually killed at birth, or may be intentionally birthed by beholder Hive Mothers. Beholders posses both male and female reproductive organs inside of their mouth, but they usually reproduce by self-fertilization since most beholders hate each other too much to willingly mate with each other. In 5th edition this is retconned and beholders now spontaneously create new beholders and beholderkin by altering reality while dreaming.

==Notable Variants==
===2nd & 3rd Edition===
====True Beholders====
* Beholder: Your basic beholder. A central eye that projects an anti-magic cone and ten smaller eyes that each fire a different ray, such as charm person, disintegrate, and flesh to stone.
* Elder Orb: A larger beholder with a much longer than normal lifespan. Always has at least 6 levels of sorcerer.
* Hive Mother/[[Hive Tyrant]]: The highest ranked of all beholders and beholderkin. Basically a bigger meaner beholder that holds beholders and beholderkin under its sway. It has the ability to control other beholders and beholderkin, and has the ability spawn new kinds of beholderkin specialized for different tasks. Beholder hives are almost always ruled by a Hive Mother, which keeps the different kinds of beholders and kin from killing each other, and when Hive Mothers belonging to the same breed come together, they can form beholder cities. In 2nd edition, Hive Mothers have their smaller eyes set in a ring around their head instead of being on the ends of stalks, making them less maneuverable but also less vulnerable to being cut off, while in 3rd edition they are just extra large beholders.

====Beholderkin====
* Gauth: Basically, babby's first beholder, with only 6 eyestalks of doom and a reduced ability to disintegrate everyone and eats magic. Looks like a smaller beholder with a ring of useless extra eyes around the central eye and four of its ten stalks don't have eyes on the end.
* Eyeball: Tiny beholder, best used as a familiar. Pretty damn adorable for a beholder, still Neutral Evil. They have four eye stalks with ray of frost, cause fear, daze, and mage hand and can only use one of them at a time. The central eye doesn't do anything.
* Death Kiss: instead of dispensing death-beams from its eyestalks, they use them to suck your blood. Their only eye has no powers, but they release electric shocks when they are injured.
* Astereater: giant space-faring asteroid beholderkin with no eyestalks that eats your ship. For some reason it likes to enslave [[Giff]] to use as soldiers. [[Spelljammer]] was weird. Beholders and other beholderkin insist that they have no relation to them.
* Examiner: Four eyestalks, four limbs, and no central eye. Their limbs let them use tools and weapons, and they can create magic items. They also regenerate 1 hit point every round.
* Observer: A powerful psionic beholder with a hard shell, six eye-stalks, three large eyes spaced evenly around its middle, and three mouths on the ends of long retractable stalks that suck blood similar to a death kiss. It uses its psionic abilities to brainwash other monsters into its loyal servants. Less evil than other beholders.
* Lensman: Beholder infantry. The lowest of all beholderkin, or at least until the Eyeball was introduced. Imagine a starfish, then add a giant eye and mouth in the middle of its body, then replace four of its five arms with the arms and legs of an ape. The eye may have one of six different powers. They do not levitate but their limbs allow them to use weapons and tools.
* Watcher: the second lowest of beholderkin. Has three normal eyes around its body and a large compound eye on the top surrounded by six eyespots, and a single tentacle on the bottom which can inflict electric shocks. Its three regular eyes each have two different powers, and the compound eye can use three of those powers. Can cast the message and tongues spells. They are cowardly and mainly act as scouts for their more powerful cousins.
* Spectator: true neutral beholderkin. It's actually pretty swell, as far as beholders go. Remember that one beholder in Baldur's Gate? They can be summoned with a ritual using four beholder's eyestalks. They make excellent guards since they are content to spend very long periods of time in deep contemplation and don't need to be fed since they can magically create their own food. Has only four eye-stalks and the central eye reflects magic instead.
* Overseer: a beholderkin that looks like a giant fleshy tree trunk with thirteen eyestalk branches, tentacles for roots, no central eye, and several mouths at the base. Yes, I realize that it looks nothing like a beholder, but the book says it is so fuck it, let's call it a beholder. Like the hive mother, it also has the ability to dominate other beholders and beholderkin. In large beholder cities, the Hive Mother dominates the Overseers, who then dominated other beholders and kin for her, thus greatly increasing the number of a beholders a Hive Mother can control at one time.
* Eye of the Deep: it's like a beholder BUT UNDERWATER! And it tastes oddly of shrimp. Also, it's got little arms with crab-pincers. Only has two eye stalks and the central eye can flash blinding light. Also can cast the spell persistent image, which it uses to create [[Trap|illusions of mermaids]] and other things to lure victims closer. Rarely interacts with other kinds of beholders due to them living in different environments.
* Director: beholder cavalry. A beholderkin with six eyestalks and three tentacles on the bottom that it uses to bond with and ride vermin, usually giant centipedes. Because haven't we all wanted to ride a giant centipede like a pony up and down the streets... SHUT UP, I DON'T JUDGE YOU! Has six eye stalks and its central eye generates a protective forcefield around itself and its mount.
* Gouger: A beholderkin created to fight beholders. In the [[Forgotten Realms]] setting, they were created by [[Phaerimm]]s. Larger than regular beholders and has four small useless legs hanging off of its body. It has the same number of eyes as a standard beholder but does not have any eye powers other than the central antimagic eye. It attacks with a 15 foot long barbed tongue which it uses to disable other beholder's eyes.
* Gorbel: Six eye stalks without any eye powers, no central eye, rubbery flesh that causes blunt weapons to harmlessly bounce off, and a pair of claws. They are stupid and try to eat anything that moves. Its claws are so strong that once it has grabbed a creature it is impossible to shake off until it is dead and its body is filled with gas that explodes on contact with air so do your best to kill them before they grab you or figure out a way to kill it without rupturing it.
* Orbus: An albino dwarf beholder with no eyes other than the anti-magic central eye but is a powerful spellcaster. They are only seen in the [[Spelljammer]] setting on beholder ships, which they are bred to power and navigate.

====Other====
* Beholder mage: when the DM wants the entire party to die horrible deaths but doesn't feel like using rocks. This is a special character class that only true beholders can take, which requires them to remove their anti-magic eye, and whenever they gain a the ability to cast a new level of spells must sacrifice one of their eye powers to turn that eyestalk into a spellstalk which casts spells of that level. At level 10, it's empty eye socket can absorb spells to heal it. All the cheese of a wizard with more spells per day, the ability to blast 10 spells at once at you as free actions, and fucking spontaneous casting. Even munchkins shit their pants in fear when they hear of these things. One of the unholy trinity of fuck off broken PCs that you can technically enter, the others being tainted scholars and Illithid Savants. And that's before you start optimizing the bastard because the fucker can still take ten more levels before becoming epic.
* Beholder Priestess: Sometimes when a beholder city is endangered the Hive Mother will called for help from The Great Mother and will be temporarily granted abilities similar to a cleric. On rare occasions this can also happen to a standard beholder, which will cause it to mutated into a Hive Mother.
* Doomsphere: The ghost of a beholder killed in by a magical explosion that haunts the area where it died. If doomsphere is defeated it will respawn in one day unless the area is exorcised.
* Death Tyrant: Basically, a Beholder lich. Yeah, you're probably fucked.
* Kasharin: A death tyrant beholder that also carries a rotting disease similar to mummy rot.
* Evil Eyes: A beholder that possesses non-standard eye powers and so is especially hated by other beholders.

===4th edition===
4e made use of quite a few different kinds of beholder, though almost all of them were pretty rapetastic, being made for higher levels. Most kinds of beholders had a Telekinesis Ray that they could use to slide enemies about, though for most that's all they do.

* Gauth - Pretty much the same as old editions, this is the pitiful little baby of the beholder family in 4e, and something you can toss at low-level parties to scare them without killing them. Level 5 Elites that can shoot fire, sleeping rays and exhaustion rays, and immobilise with its central eye.
* Bloodkiss - Another carry-over, and the second-weakest beholder statted, this one got the Undead subtype for some reason (guess they didn't read up and thought it was "just" a beholder vampire). Level 9 Solo Controller that relies on its blood-sucking tentacles to rip up anything in reach, though it also packs a psychic + dazing effect Death Scream attack and can hit people a lot of times.
* Eye of Shadow - Beholders who spent too long in the shadowfell, dissolving into a blot of darkness and hate. Fairly puny (level 12 Elite), but seriously trolling, with blinding rays, thundering rays, freezing rays, and the ability to pull off a "teleport 20 squares and then be invisible" trick.
* Eye of Flame - A beholder that specialises in burninating shit. Central eye gives vulnerability to fire and causes fire attacks to do ongoing, eyestalks blast foes with fire and fear effects. A low-Paragon tier (level 13 Elite) foe.
* Eye of Frost - We got a burn-your-ass beholder, so evidently we need a freezinating beholder. Slightly tougher (1 level higher) than its counterpart. Central eye means cold damage can immobilise those it looks at... weirdly, its got two kinds of freezing rays; one that does a lot of cold damage, one that does less cold damage but freezes your ass solid.
* Beholder Spawn - Baby beholders wanna eat your face, too. Level 15 Minions that can bite or do elemental damage with their eye-rays.
* Death Tyrant - Zombie Eye Tyrants, pretty much. Way weaker than their older namesakes (level 15 Solo). Central eye can strip away necrotic resistance (guess what kind of damage it does most) and slow you, and eyebeams focused on kill-you-dead. Choice is whether it just necrotic damages you to death, petrifies you, makes you die, or makes you die and then come back as a ghoul. Oh, and it has a fear ray too.
* Ghost Beholder - Dead Eye Tyrant who came back as a ghost. A level weaker and only an Elite, but still pretty nasty. Freezing eye rays and the ability to possess and mind control your dudes: not a lot of fun if your Will is shitty.
* Eye Tyrant - Your basic beholder for this edition, and pretty damn nasty (level 19 Solo). Can daze you with its central eye, or use its eyestalks to cause radiant and necrotic damage, put you to sleep, paralyze you, confuse you, terrify you, petrify you, disintegrate you or kill you outright.
* Eye of Chaos - Now we're getting into the big guns. Beholders that have been warped by the abyss, changing their alignment to chaotic evil and making them more similar to demons in their behavior. Level 25 Elites that will drive you almost as crazy as themselves, with the ability to lock you down to at-will powers only with their central eye and hit you with rays of force, blinding, confounding, madness, fear or teleportation.
* Ultimate Tyrant - They ain't fucking kidding when they named this bastard. Level 29 Solo - there are ancient dragons that aren't this nasty! Central eye locks you down, other eyes can drive you mad, unravel you, dissolve you, burn you, freeze you, drag you around, petrify you, disintegrate you, pull you closer or hurl you away.
* Eternal Tyrant - Because even the Ultimate Tyrant isn't ultimate enough. This bastard is an undead version of the Ultimate Tyrant that comes in a pair of linked entities; the Shell, a beholder [[golem]] (Level 31 Elite Brute) and the Essence, a hyper-powerful beholder [[ghost]] (level 33 Elite Artillery). These assholes are literally god-tier monsters - you had damn well better know what you're doing when you fight an Eternal Tyrant!

===5th Edition===
5e's first Monster Manual provides three forms of beholder; common beholder (or Eye Tyrant), Death Tyrant, and Spectator. The first two variants are what 5e calls Legendary creatures, meaning they have extra powers in their lairs that they can trigger on Initiative Count 20, certain specific effects mark the regions in which they lair, and they have special Legendary Actions that they can perform outside of the normal turn sequence. Their legendary ego has been given up a serious boost; now, beholders mutate at random just by accidentally thinking too hard, their ego is that overpowering. This is also how they reproduce now: by sleeping and dreaming of other beholders, bending reality in that way.

* Beholder: You know it, you hate it. Challenge level 13. Has its old antimagic cone central eye back, a bite attack for piercing damage, and ten eye rays, of which it can use three each round, rolling randomly to determine which three it has. Charm ray, paralyzing ray, fear ray, slowing ray, enervation ray, telekinetic ray, sleep ray, petrification ray, disintegration ray and death ray. It can burn one of its three legendary actions at the end of another creature's turn to blast somebody with a random eye ray. Its lair effects consist of three options; change a 50ft square up to 120ft distant into slimy difficult terrain, make any walls within 120ft sprout flailing appendages that'll grapple anyone within 10ft who can't beat a DC 15 Strength (Athletics) or Dexterity (Acrobatics) check, or cause an eye to pop up on any solid surface within 60ft that can then shoot a random eye ray at any enemy within its sight. For region effects, they're all fluffy; creatures within 1 mile sometimes feel they're being watched, or minor reality warps that affect inanimate objects (markings changing on a wall, slime coating a statue, etc) pop up whilst the beholder is sleeping. Volo's Guide to Monsters introduced a table of potential alternate eye rays, in case your party was feeling complacent.
* Death Tyrant: A beholder who dreamed of living forever. So it died in its sleep and became an undead beholder skull with ghostly eyes. It trades the antimagic cone for a negative energy cone (creatures can't regain hitpoints, humanoids that die in its area of effect become zombies under the death tyrant's command on the next turn). It has the same eye rays and legendary actions as the beholder. Its lair actions are variants of the beholder's - its grabbing walls are DC 17 and reach into the Ethereal Plane, it creates a 50ft cube of lightly obscured difficult terrain, and it can create a spectral eye at any point within 50ft, which can also target foes on the Ethereal Plane. It has one crunchy regional effect; a creature that is both hostile to the death tyrant and aware of its existence must roll a D20 if it finishes a long rest within 1 mile of the death tyrant's lair. On a 10 or less, it gets zapped with a random eye ray.
* Spectator: A lesser beholder variant with only four eye stalks, conjured from another plane of existence via a ritual that requires four beholder eyestalks as material components. It's only Challenge level 3 and it's Lawful Neutral, rather than the Lawful Evil of the others. It has a Confusion Ray, a Paralyzing Ray, a Fear Ray and a Wounding Ray, and it can magically create all the food and water it needs to sustain itself each day. It's a fool's gambit to attack it with spells thanks to its Spell Reflection reaction, which lets it retarget a spell that missed the spectator, or which forced a save that the spectator passed, against another creature within the spectator's line of sight and that is at least 30 feet from the spectator.
* Beholder Zombie: Much weaker than a living beholder. Loses most of its eye rays and its anti-magic cone.
* Death's Kiss: A Beholder who had nightmares about bleeding out spawns a vampiric tentacle monster, using toothy mouth-stalks to voraciously suck the blood from other creatures. It also bleeds lightning, for some reason. Not as smart as a normal beholder, but for this reason not as egotistical or paranoid. Added in Volo's Guide to Monsters.
* Gauth: A smaller beholder who sometimes shows up if you screw up the ritual to summon a spectator; it's got six eyestalks, four tentacles, and smaller eyes all around its central eye, so it's hard to understand how wizards can get confused when it lies and claims to be the real deal. The issue is that Gauths are magic eaters, sucking the juice from magical items to sustain themselves, so you can see why that makes them pretty piss-poor guards for a wizard's lair. They're weaker than true beholders and also less xenophobic. Also, they explode when you kill them.
* Gazer: A ridiculously adorable and weak little beholder (only Challenge 1/2 - that is, a ''twenty-sixth'' of the strength of a true beholder) that is sometimes dreamed into being. They're so amusingly pathetic that even pure beholders often keep them as pets, and they have the same sadistic ego of a full beholder in miniature. Have caused a lot of argument over whether the sidebar on gazer familiars is intended for PCs as well or just for mage NPCs, and if so if house rules should be used to slot them in as Chain Pact warlock familiars, let them take the action to fire their eye-rays, etc.
* Mindwitness: A beholder converted into an [[illithid]]-like creature via ceremorphosis. Now that those of you who aren't currently running from your computers in terror have stopped screaming, the end result is less "terrifying perfect marriage of beholder eye-rays with illithid mind rape and the combined egotism of both" and more "quasi-lobotomized docile [[Adeptus Astra Telepathica#Astropaths|glorified psionic email server]]," though still smarter than the average human. Notably, if the illithids and elder brains they serve are slaughtered and they survive, mindwitnesses tend to drift around looking for other psionic creatures to serve, taking on the alignments and worldviews of those they meet, be they kindly [[flumph]]s or evil [[demon]]s. Four of their eyestalks become tentacles, but they have six kinds of eyerays: fear, telekinetic, and slowing rays like those of their normal cousins, but also aversion rays that cause disadvantage on attack rolls, stunning rays that stun creatures, and a psychic ray that just causes a pile of psychic damage.

==Similar Monsters==
Beholders are not the only monsters that look like floating orbs with eyes.
* Gas Spore: Not a true beholder or beholderkin, but a [[fungus]] that resembles a beholder. May have been created by a beholder mage, or may be a fungus that took on the form of the beholder that it fed on, or maybe it's just mundane evolutionary mimicry. Beholders sometimes cultivate them in their cities for defense.
* Thagar: Also known as the Beholdereater, it is a predator that eats beholders. Is a giant orb covered in eyes with several mouths on the ends of stalks. It does not have any eye powers, but it is immune to mind affecting magic and highly resistant to it's body being physically affected by magic, so there isn't much a beholder can do against it.
* Deep spawn: An orb with six large tentacles and several retractable eye stalk. Three of it's tentacles end in mouths, and the other three can wield weapons. It has the ability to give birth to loyal clones of creatures it has previously eaten, making them useful for villains who want to populate their dungeons with a variety of monsters. Relation to beholders unknown.
* Gibbering Orb: An epic version of the [[Gibbering Mouther]]. An amorphous orb covered in mouths and eyes, which have eye rays similar to a beholder. Possibly is the common ancestor of beholders and gibbering mouthers, though this would conflict with the belief that the Great Mother created beholders. Fourth edition also introduced the Gibbering Abomination, a middle ground between the mouther and the orb which also eye rays.
* Lurking strangler: These creatures are to beholders what monkeys are to humans. A tiny aberration that looks like a pair of flying eyeballs connected by a cord of muscle. It likes to strangling sleeping enemies to death, and it can put enemies to sleep with one of its two eye rays. Beholders sometimes keep these things as pets.
* Fihyr: A living manifestation of nightmares that forms when a large number of people in an area all have nightmares in one night. It has a roughly spherical body covered in eyes, mouths, and tentacles. No relation to beholders.
* [[Astral Dreadnought]]: A huge predator that lives in the [[Astral Plane]] that has a single eye with anti-magic abilities similar to a beholder's central eye. Relation to beholders unknown.

==Notable Beholders==
*Large Luigi, a relatively friendly beholder who works as a barkeep in the [[Spelljammer]] setting.
*That beholder head of the thieves' guild who was the first major boss in [[Baldur's Gate: Dark Alliance]]
*Another beholder head of another thieves' guild who was the final boss of the first Eye of the Beholder game.
*That funny spectator you kept running into and quasi-befriended in [[Baldur's Gate|Baldur's Gate II]]
*That blind death tyrant boss you had to get a special god-killing magic wand to kill in [[Baldur's Gate|Baldur's Gate II]]
*That beholder in [[Dungeons and Dragons: Heroes]]
*That beholder in Futurama who's there for no apparent reason (was meant to be guarding some passage in the Central Bureaucracy but fell asleep on the job)
*Xanathar, the writer of "Xanathar's guide to everything" and head of Skullport's Thieves' Guild, which includes new options for classes and backgrounds, along with his snide comments running throughout. Apparently he's only one of many beholders to have used the title since the first one seized power. Notable for being one of the few beholders to remotely care for a being other than itself, he really loves his pet goldfish. It is kind of adorable. What he doesn't know is that his beloved goldfish has been replaced several times by the Thieves' Guild since goldfish don't live very long and he would [[RAGE|not be happy if he ever found out]].

==Beholders as Monstergirls==
[[File:Gazer.jpg|200px|thumb|right|No, you're not dreaming, this is a Beholder in monstergirl form.]]{{Monstergirls}}

[[rule 34|The proof that nothing, ab-so-lu-te-ly nothing is sacred,]] even Beholders got anthropomorphised into a sexy almost-human female by [[/d/|those irremediably insane weebs]]. Goddamit, Japan!

Gazers (as they are typically known due to copyright) are often depicted as arrogant, selfish beings that do not hesitate to use their eye ray powers to get what they want. Of course, fitting for a [[monstergirl]]s setting, their powers are [[PROMOTIONS|less destructive]] than that of a D&D Beholder, going more toward charm, hypnotism and mind control.

Still, beholder-girls are a rarity, simply because there's something rather counter-intuitive about turning a floating head full of teeth and eyes into a monstergirl. Perhaps the most well known example of them on /tg/ is the Gazer of the [[Monster Girl Encyclopedia]], whose smug grin currently adorns this section of the page. Described as spiteful and full of themselves, their deepest secret is that this is mostly bluster to cover up feelings of insecurity about their looks. They specialize in hypnotic spells, mostly to brainwash men into falling in love with them.

[[Category:Dungeons & Dragons]][[Category:Monsters]]
[[Image:Beholder_balloon.jpg|thumb|right|Drow clowns make a different kind of balloon animal]]

A '''beholder''' is a giant lumpy... thing that looks like a floating octopus with a giant eye in the middle. The tentacles also have eyes at the end of them. Yuck.

Beholders, like [[Illithid|Mind Flayer]]s, are considered "intellectual property" of <s>TSR</s> Wizards of the Coast, so they aren't allowed to be used in third party D&D supplements or in [[Pathfinder]] as they were not covered under the [[OGL|Open Gaming License]]. This naturally doesn't stop [[ChapterHouse Studios|weirdly]] [[Original character, do not steal|similar]] creatures from appearing in various [[weeaboo]] JRPGs and related works, where they're usually called "gazers" or similar. Yes, this includes [[Monstergirls]]. Of course one game even used the name beholder, but we all excuse it, because this game is [[Heroes of Might and Magic|THE GAME. THE LEGEND.]]

The Beholder first appeared on the cover of the [[Greyhawk]] supplement for the Original Dungeons and Dragons. The creation of [[Spelljammer]] where beholders play an major role resulted in the creation of many varieties of beholders. Much information about their biology and culture was revealed in the book [[Lords of Madness]]. They also got an entire book to themselves in second edition called ''I, Tyrant''.

==Personality and Characteristics==

Beholders are selfish bastards who love to manipulate and enslave any races considered beneath themselves (i.e. every other species). They are extremely [[Imperium|xenophobic]] even going so far as to kill other individuals of their species that look even ''slightly'' different from themselves, though they always go after the more extreme divergences first; two beholders will gang up on the "freak" with scales and fiery eyes before trying to kill each other over the differences in their numbers of teeth. Soooo basically the D&D equivalent of a [[Doctor Who|Dalek]]. Even if two beholders look identical to each other they will struggle to cooperate with each other due to their extreme paranoia. Large groups of beholders can only work together while under the mind control of a beholder hive mother or an overseer.

Despite this, or perhaps because of it, the beholder race has a lot of genetic variety (as evidenced by the number of Beholder variants, all of whom hate each other, as listed below). They are greedy, often living in dungeons stuffed with valuables. They can cast magic from their eyes and often rule over unwilling souls through domination. One even runs the Thieves' Guild of Skullport, the most recent of several beholders to have done so.

Beholders worship the [[Great Mother]] and due to their massive egos, each beholder is convinced that not only does the Great Mother look exactly like itself, but also that it's ''literally'' their mother (false memories are funny like that). Beholders would be shocked and possibly driven mad (or madder than they already are) if they found out that the Great Mother, despite possessing vast knowledge, is completely insane and acts mainly on instinct instead of logic, unlike her children. Beholders also have another god named [[Gzemnid]] who is associated with gases and deception. Worshipers of Gzemnid are considered [[Heresy|heretics]] by other beholders because they believe that the Great Mother is actually constantly changing in appearance and creates different breeds of beholders every time she reproduces so there is no master race of beholder.

Part of the reason why beholders are so egotistical and paranoid is because they actually possess two minds. They do most of their thinking with their rational mind, but they also possess an intuitive mind which can censor the beholder from experiencing anything that might threaten their ego. This causes the beholder's rational mind to have no memory of times when they failed at anything, and to try to explain the missing memories with conspiracy theories.

Like [[Aboleth]]s, when a beholder is born, they inherent memories from their parent, though not a complete set of memories. This is why trying to raise a baby beholder to be good is a terrible idea, as their xenophobic beliefs are one of the things they inherent.

While good beholder technically are possible, they are extremely rare because turning good requires a beholder to give up on everything they have ever believed since birth, which by beholder standards would make them insane even compared to other insane beholders. Even beholders that are tolerant enough of non-beholders to work with them are usually still evil and tend to become crime bosses.

A standard beholder has a roughly spherical body with no distinction between their head and torso. Their skin comes in a wide variety of colors and textures. They have large mouth full of sharp teeth and a single central eye that constantly projects an anti-magic cone when it is open. At the top of their head are ten stalks tipped with smaller eyes. In some beholder breeds the eye stalks resemble tentacles while in others they are jointed. Each of theses eyes can fire a magical ray at will, with each eye having a different ray. Theses rays are: Charm Person, Charm Monster, Sleep, Telekinesis, Flesh to Stone, Disintegrate, Fear, Slow, Cause Serious Wounds, and Death. They have no other appendages besides these eye stalks. A beholder can levitate and fly. This ability is not magical in nature as it isn't affected by anti-magic fields or else beholders would knock each other out of the air by looking at one another. Beholders with significant deviations from this form are known as Beholderkin. Beholderkin may be born randomly from beholders, and are usually killed at birth, or may be intentionally birthed by beholder Hive Mothers. Beholders posses both male and female reproductive organs inside of their mouth, but they usually reproduce by self-fertilization since most beholders hate each other too much to willingly mate with each other. In 5th edition this is retconned and beholders now spontaneously create new beholders and beholderkin by altering reality while dreaming.

==Notable Variants==
===2nd & 3rd Edition===
====True Beholders====
* Beholder: Your basic beholder. A central eye that projects an anti-magic cone and ten smaller eyes that each fire a different ray, such as charm person, disintegrate, and flesh to stone.
* Elder Orb: A larger beholder with a much longer than normal lifespan. Always has at least 6 levels of sorcerer.
* Hive Mother/[[Hive Tyrant]]: The highest ranked of all beholders and beholderkin. Basically a bigger meaner beholder that holds beholders and beholderkin under its sway. It has the ability to control other beholders and beholderkin, and has the ability spawn new kinds of beholderkin specialized for different tasks. Beholder hives are almost always ruled by a Hive Mother, which keeps the different kinds of beholders and kin from killing each other, and when Hive Mothers belonging to the same breed come together, they can form beholder cities. In 2nd edition, Hive Mothers have their smaller eyes set in a ring around their head instead of being on the ends of stalks, making them less maneuverable but also less vulnerable to being cut off, while in 3rd edition they are just extra large beholders.

====Beholderkin====
* Gauth: Basically, babby's first beholder, with only 6 eyestalks of doom and a reduced ability to disintegrate everyone and eats magic. Looks like a smaller beholder with a ring of useless extra eyes around the central eye and four of its ten stalks don't have eyes on the end.
* Eyeball: Tiny beholder, best used as a familiar. Pretty damn adorable for a beholder, still Neutral Evil. They have four eye stalks with ray of frost, cause fear, daze, and mage hand and can only use one of them at a time. The central eye doesn't do anything.
* Death Kiss: instead of dispensing death-beams from its eyestalks, they use them to suck your blood. Their only eye has no powers, but they release electric shocks when they are injured.
* Astereater: giant space-faring asteroid beholderkin with no eyestalks that eats your ship. For some reason it likes to enslave [[Giff]] to use as soldiers. [[Spelljammer]] was weird. Beholders and other beholderkin insist that they have no relation to them.
* Examiner: Four eyestalks, four limbs, and no central eye. Their limbs let them use tools and weapons, and they can create magic items. They also regenerate 1 hit point every round.
* Observer: A powerful psionic beholder with a hard shell, six eye-stalks, three large eyes spaced evenly around its middle, and three mouths on the ends of long retractable stalks that suck blood similar to a death kiss. It uses its psionic abilities to brainwash other monsters into its loyal servants. Less evil than other beholders.
* Lensman: Beholder infantry. The lowest of all beholderkin, or at least until the Eyeball was introduced. Imagine a starfish, then add a giant eye and mouth in the middle of its body, then replace four of its five arms with the arms and legs of an ape. The eye may have one of six different powers. They do not levitate but their limbs allow them to use weapons and tools.
* Watcher: the second lowest of beholderkin. Has three normal eyes around its body and a large compound eye on the top surrounded by six eyespots, and a single tentacle on the bottom which can inflict electric shocks. Its three regular eyes each have two different powers, and the compound eye can use three of those powers. Can cast the message and tongues spells. They are cowardly and mainly act as scouts for their more powerful cousins.
* Spectator: true neutral beholderkin. It's actually pretty swell, as far as beholders go. Remember that one beholder in Baldur's Gate? They can be summoned with a ritual using four beholder's eyestalks. They make excellent guards since they are content to spend very long periods of time in deep contemplation and don't need to be fed since they can magically create their own food. Has only four eye-stalks and the central eye reflects magic instead.
* Overseer: a beholderkin that looks like a giant fleshy tree trunk with thirteen eyestalk branches, tentacles for roots, no central eye, and several mouths at the base. Yes, I realize that it looks nothing like a beholder, but the book says it is so fuck it, let's call it a beholder. Like the hive mother, it also has the ability to dominate other beholders and beholderkin. In large beholder cities, the Hive Mother dominates the Overseers, who then dominated other beholders and kin for her, thus greatly increasing the number of a beholders a Hive Mother can control at one time.
* Eye of the Deep: it's like a beholder BUT UNDERWATER! And it tastes oddly of shrimp. Also, it's got little arms with crab-pincers. Only has two eye stalks and the central eye can flash blinding light. Also can cast the spell persistent image, which it uses to create [[Trap|illusions of mermaids]] and other things to lure victims closer. Rarely interacts with other kinds of beholders due to them living in different environments.
* Director: beholder cavalry. A beholderkin with six eyestalks and three tentacles on the bottom that it uses to bond with and ride vermin, usually giant centipedes. Because haven't we all wanted to ride a giant centipede like a pony up and down the streets... SHUT UP, I DON'T JUDGE YOU! Has six eye stalks and its central eye generates a protective forcefield around itself and its mount.
* Gouger: A beholderkin created to fight beholders. In the [[Forgotten Realms]] setting, they were created by [[Phaerimm]]s. Larger than regular beholders and has four small useless legs hanging off of its body. It has the same number of eyes as a standard beholder but does not have any eye powers other than the central antimagic eye. It attacks with a 15 foot long barbed tongue which it uses to disable other beholder's eyes.
* Gorbel: Six eye stalks without any eye powers, no central eye, rubbery flesh that causes blunt weapons to harmlessly bounce off, and a pair of claws. They are stupid and try to eat anything that moves. Its claws are so strong that once it has grabbed a creature it is impossible to shake off until it is dead and their bodies are filled with gas that explodes on contact with air so do your best to kill them before they grab you or figure out a way to kill it without rupturing it.
* Orbus: An albino dwarf beholder with no eyes other than the anti-magic central eye but is a powerful spellcaster. They are only seen in the [[Spelljammer]] setting on beholder ships, which they are bred to power and navigate.

====Other====
* Beholder mage: when the DM wants the entire party to die horrible deaths but doesn't feel like using rocks. This is a special character class that only true beholders can take, which requires them to remove their anti-magic eye, and whenever they gain a the ability to cast a new level of spells must sacrifice one of their eye powers to turn that eyestalk into a spellstalk which casts spells of that level. At level 10, it's empty eye socket can absorb spells to heal it. All the cheese of a wizard with more spells per day, the ability to blast 10 spells at once at you as free actions, and fucking spontaneous casting. Even munchkins shit their pants in fear when they hear of these things. One of the unholy trinity of fuck off broken PCs that you can technically enter, the others being tainted scholars and Illithid Savants. And that's before you start optimizing the bastard because the fucker can still take ten more levels before becoming epic.
* Beholder Priestess: Sometimes when a beholder city is endangered the Hive Mother will called for help from The Great Mother and will be temporarily granted abilities similar to a cleric. On rare occasions this can also happen to a standard beholder, which will cause it to mutated into a Hive Mother.
* Doomsphere: The ghost of a beholder killed in by a magical explosion that haunts the area where it died. If doomsphere is defeated it will respawn in one day unless the area is exorcised.
* Death Tyrant: Basically, a Beholder lich. Yeah, you're probably fucked.
* Kasharin: A death tyrant beholder that also carries a rotting disease similar to mummy rot.
* Evil Eyes: A beholder that possesses non-standard eye powers and so is especially hated by other beholders.

===4th edition===
4e made use of quite a few different kinds of beholder, though almost all of them were pretty rapetastic, being made for higher levels. Most kinds of beholders had a Telekinesis Ray that they could use to slide enemies about, though for most that's all they do.

* Gauth - Pretty much the same as old editions, this is the pitiful little baby of the beholder family in 4e, and something you can toss at low-level parties to scare them without killing them. Level 5 Elites that can shoot fire, sleeping rays and exhaustion rays, and immobilise with its central eye.
* Bloodkiss - Another carry-over, and the second-weakest beholder statted, this one got the Undead subtype for some reason (guess they didn't read up and thought it was "just" a beholder vampire). Level 9 Solo Controller that relies on its blood-sucking tentacles to rip up anything in reach, though it also packs a psychic + dazing effect Death Scream attack and can hit people a lot of times.
* Eye of Shadow - Beholders who spent too long in the shadowfell, dissolving into a blot of darkness and hate. Fairly puny (level 12 Elite), but seriously trolling, with blinding rays, thundering rays, freezing rays, and the ability to pull off a "teleport 20 squares and then be invisible" trick.
* Eye of Flame - A beholder that specialises in burninating shit. Central eye gives vulnerability to fire and causes fire attacks to do ongoing, eyestalks blast foes with fire and fear effects. A low-Paragon tier (level 13 Elite) foe.
* Eye of Frost - We got a burn-your-ass beholder, so evidently we need a freezinating beholder. Slightly tougher (1 level higher) than its counterpart. Central eye means cold damage can immobilise those it looks at... weirdly, its got two kinds of freezing rays; one that does a lot of cold damage, one that does less cold damage but freezes your ass solid.
* Beholder Spawn - Baby beholders wanna eat your face, too. Level 15 Minions that can bite or do elemental damage with their eye-rays.
* Death Tyrant - Zombie Eye Tyrants, pretty much. Way weaker than their older namesakes (level 15 Solo). Central eye can strip away necrotic resistance (guess what kind of damage it does most) and slow you, and eyebeams focused on kill-you-dead. Choice is whether it just necrotic damages you to death, petrifies you, makes you die, or makes you die and then come back as a ghoul. Oh, and it has a fear ray too.
* Ghost Beholder - Dead Eye Tyrant who came back as a ghost. A level weaker and only an Elite, but still pretty nasty. Freezing eye rays and the ability to possess and mind control your dudes: not a lot of fun if your Will is shitty.
* Eye Tyrant - Your basic beholder for this edition, and pretty damn nasty (level 19 Solo). Can daze you with its central eye, or use its eyestalks to cause radiant and necrotic damage, put you to sleep, paralyze you, confuse you, terrify you, petrify you, disintegrate you or kill you outright.
* Eye of Chaos - Now we're getting into the big guns. Beholders that have been warped by the abyss, changing their alignment to chaotic evil and making them more similar to demons in their behavior. Level 25 Elites that will drive you almost as crazy as themselves, with the ability to lock you down to at-will powers only with their central eye and hit you with rays of force, blinding, confounding, madness, fear or teleportation.
* Ultimate Tyrant - They ain't fucking kidding when they named this bastard. Level 29 Solo - there are ancient dragons that aren't this nasty! Central eye locks you down, other eyes can drive you mad, unravel you, dissolve you, burn you, freeze you, drag you around, petrify you, disintegrate you, pull you closer or hurl you away.
* Eternal Tyrant - Because even the Ultimate Tyrant isn't ultimate enough. This bastard is an undead version of the Ultimate Tyrant that comes in a pair of linked entities; the Shell, a beholder [[golem]] (Level 31 Elite Brute) and the Essence, a hyper-powerful beholder [[ghost]] (level 33 Elite Artillery). These assholes are literally god-tier monsters - you had damn well better know what you're doing when you fight an Eternal Tyrant!

===5th Edition===
5e's first Monster Manual provides three forms of beholder; common beholder (or Eye Tyrant), Death Tyrant, and Spectator. The first two variants are what 5e calls Legendary creatures, meaning they have extra powers in their lairs that they can trigger on Initiative Count 20, certain specific effects mark the regions in which they lair, and they have special Legendary Actions that they can perform outside of the normal turn sequence. Their legendary ego has been given up a serious boost; now, beholders mutate at random just by accidentally thinking too hard, their ego is that overpowering. This is also how they reproduce now: by sleeping and dreaming of other beholders, bending reality in that way.

* Beholder: You know it, you hate it. Challenge level 13. Has its old antimagic cone central eye back, a bite attack for piercing damage, and ten eye rays, of which it can use three each round, rolling randomly to determine which three it has. Charm ray, paralyzing ray, fear ray, slowing ray, enervation ray, telekinetic ray, sleep ray, petrification ray, disintegration ray and death ray. It can burn one of its three legendary actions at the end of another creature's turn to blast somebody with a random eye ray. Its lair effects consist of three options; change a 50ft square up to 120ft distant into slimy difficult terrain, make any walls within 120ft sprout flailing appendages that'll grapple anyone within 10ft who can't beat a DC 15 Strength (Athletics) or Dexterity (Acrobatics) check, or cause an eye to pop up on any solid surface within 60ft that can then shoot a random eye ray at any enemy within its sight. For region effects, they're all fluffy; creatures within 1 mile sometimes feel they're being watched, or minor reality warps that affect inanimate objects (markings changing on a wall, slime coating a statue, etc) pop up whilst the beholder is sleeping. Volo's Guide to Monsters introduced a table of potential alternate eye rays, in case your party was feeling complacent.
* Death Tyrant: A beholder who dreamed of living forever. So it died in its sleep and became an undead beholder skull with ghostly eyes. It trades the antimagic cone for a negative energy cone (creatures can't regain hitpoints, humanoids that die in its area of effect become zombies under the death tyrant's command on the next turn). It has the same eye rays and legendary actions as the beholder. Its lair actions are variants of the beholder's - its grabbing walls are DC 17 and reach into the Ethereal Plane, it creates a 50ft cube of lightly obscured difficult terrain, and it can create a spectral eye at any point within 50ft, which can also target foes on the Ethereal Plane. It has one crunchy regional effect; a creature that is both hostile to the death tyrant and aware of its existence must roll a D20 if it finishes a long rest within 1 mile of the death tyrant's lair. On a 10 or less, it gets zapped with a random eye ray.
* Spectator: A lesser beholder variant with only four eye stalks, conjured from another plane of existence via a ritual that requires four beholder eyestalks as material components. It's only Challenge level 3 and it's Lawful Neutral, rather than the Lawful Evil of the others. It has a Confusion Ray, a Paralyzing Ray, a Fear Ray and a Wounding Ray, and it can magically create all the food and water it needs to sustain itself each day. It's a fool's gambit to attack it with spells thanks to its Spell Reflection reaction, which lets it retarget a spell that missed the spectator, or which forced a save that the spectator passed, against another creature within the spectator's line of sight and that is at least 30 feet from the spectator.
* Beholder Zombie: Much weaker than a living beholder. Loses most of its eye rays and its anti-magic cone.
* Death's Kiss: A Beholder who had nightmares about bleeding out spawns a vampiric tentacle monster, using toothy mouth-stalks to voraciously suck the blood from other creatures. It also bleeds lightning, for some reason. Not as smart as a normal beholder, but for this reason not as egotistical or paranoid. Added in Volo's Guide to Monsters.
* Gauth: A smaller beholder who sometimes shows up if you screw up the ritual to summon a spectator; it's got six eyestalks, four tentacles, and smaller eyes all around its central eye, so it's hard to understand how wizards can get confused when it lies and claims to be the real deal. The issue is that Gauths are magic eaters, sucking the juice from magical items to sustain themselves, so you can see why that makes them pretty piss-poor guards for a wizard's lair. They're weaker than true beholders and also less xenophobic. Also, they explode when you kill them.
* Gazer: A ridiculously adorable and weak little beholder (only Challenge 1/2 - that is, a ''twenty-sixth'' of the strength of a true beholder) that is sometimes dreamed into being. They're so amusingly pathetic that even pure beholders often keep them as pets, and they have the same sadistic ego of a full beholder in miniature. Have caused a lot of argument over whether the sidebar on gazer familiars is intended for PCs as well or just for mage NPCs, and if so if house rules should be used to slot them in as Chain Pact warlock familiars, let them take the action to fire their eye-rays, etc.
* Mindwitness: A beholder converted into an [[illithid]]-like creature via ceremorphosis. Now that those of you who aren't currently running from your computers in terror have stopped screaming, the end result is less "terrifying perfect marriage of beholder eye-rays with illithid mind rape and the combined egotism of both" and more "quasi-lobotomized docile [[Adeptus Astra Telepathica#Astropaths|glorified psionic email server]]," though still smarter than the average human. Notably, if the illithids and elder brains they serve are slaughtered and they survive, mindwitnesses tend to drift around looking for other psionic creatures to serve, taking on the alignments and worldviews of those they meet, be they kindly [[flumph]]s or evil [[demon]]s. Four of their eyestalks become tentacles, but they have six kinds of eyerays: fear, telekinetic, and slowing rays like those of their normal cousins, but also aversion rays that cause disadvantage on attack rolls, stunning rays that stun creatures, and a psychic ray that just causes a pile of psychic damage.

==Similar Monsters==
Beholders are not the only monsters that look like floating orbs with eyes.
* Gas Spore: Not a true beholder or beholderkin, but a [[fungus]] that resembles a beholder. May have been created by a beholder mage, or may be a fungus that took on the form of the beholder that it fed on, or maybe it's just mundane evolutionary mimicry. Beholders sometimes cultivate them in their cities for defense.
* Thagar: Also known as the Beholdereater, it is a predator that eats beholders. Is a giant orb covered in eyes with several mouths on the ends of stalks. It does not have any eye powers, but it is immune to mind affecting magic and highly resistant to it's body being physically affected by magic, so there isn't much a beholder can do against it.
* Deep spawn: An orb with six large tentacles and several retractable eye stalk. Three of it's tentacles end in mouths, and the other three can wield weapons. It has the ability to give birth to loyal clones of creatures it has previously eaten, making them useful for villains who want to populate their dungeons with a variety of monsters. Relation to beholders unknown.
* Gibbering Orb: An epic version of the [[Gibbering Mouther]]. An amorphous orb covered in mouths and eyes, which have eye rays similar to a beholder. Possibly is the common ancestor of beholders and gibbering mouthers, though this would conflict with the belief that the Great Mother created beholders. Fourth edition also introduced the Gibbering Abomination, a middle ground between the mouther and the orb which also eye rays.
* Lurking strangler: These creatures are to beholders what monkeys are to humans. A tiny aberration that looks like a pair of flying eyeballs connected by a cord of muscle. It likes to strangling sleeping enemies to death, and it can put enemies to sleep with one of its two eye rays. Beholders sometimes keep these things as pets.
* Fihyr: A living manifestation of nightmares that forms when a large number of people in an area all have nightmares in one night. It has a roughly spherical body covered in eyes, mouths, and tentacles. No relation to beholders.
* [[Astral Dreadnought]]: A huge predator that lives in the [[Astral Plane]] that has a single eye with anti-magic abilities similar to a beholder's central eye. Relation to beholders unknown.

==Notable Beholders==
*Large Luigi, a relatively friendly beholder who works as a barkeep in the [[Spelljammer]] setting.
*That beholder head of the thieves' guild who was the first major boss in [[Baldur's Gate: Dark Alliance]]
*Another beholder head of another thieves' guild who was the final boss of the first Eye of the Beholder game.
*That funny spectator you kept running into and quasi-befriended in [[Baldur's Gate|Baldur's Gate II]]
*That blind death tyrant boss you had to get a special god-killing magic wand to kill in [[Baldur's Gate|Baldur's Gate II]]
*That beholder in [[Dungeons and Dragons: Heroes]]
*That beholder in Futurama who's there for no apparent reason (was meant to be guarding some passage in the Central Bureaucracy but fell asleep on the job)
*Xanathar, the writer of "Xanathar's guide to everything" and head of Skullport's Thieves' Guild, which includes new options for classes and backgrounds, along with his snide comments running throughout. Apparently he's only one of many beholders to have used the title since the first one seized power. Notable for being one of the few beholders to remotely care for a being other than itself, he really loves his pet goldfish. It is kind of adorable. What he doesn't know is that his beloved goldfish has been replaced several times by the Thieves' Guild since goldfish don't live very long and he would [[RAGE|not be happy if he ever found out]].

==Beholders as Monstergirls==
[[File:Gazer.jpg|200px|thumb|right|No, you're not dreaming, this is a Beholder in monstergirl form.]]{{Monstergirls}}

[[rule 34|The proof that nothing, ab-so-lu-te-ly nothing is sacred,]] even Beholders got anthropomorphised into a sexy almost-human female by [[/d/|those irremediably insane weebs]]. Goddamit, Japan!

Gazers (as they are typically known due to copyright) are often depicted as arrogant, selfish beings that do not hesitate to use their eye ray powers to get what they want. Of course, fitting for a [[monstergirl]]s setting, their powers are [[PROMOTIONS|less destructive]] than that of a D&D Beholder, going more toward charm, hypnotism and mind control.

Still, beholder-girls are a rarity, simply because there's something rather counter-intuitive about turning a floating head full of teeth and eyes into a monstergirl. Perhaps the most well known example of them on /tg/ is the Gazer of the [[Monster Girl Encyclopedia]], whose smug grin currently adorns this section of the page. Described as spiteful and full of themselves, their deepest secret is that this is mostly bluster to cover up feelings of insecurity about their looks. They specialize in hypnotic spells, mostly to brainwash men into falling in love with them.

Fiend Folio

2020-07-15T05:48:12Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* 1st Edition */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.

Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]

* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books.

* [[Selkie]]
* [[Senmurv]], a lawful good [[Furry|sparkledog]] with bird wings instead of arms.
* [[Shadar-Kai]], the page for details. This book also contains rules for several Shadar-Kai magic items. The gal-ralan is an armband Shadar-kai use to protect themselves from the shadow curse that anchors the soul to their body and enhances saving throws, but also causes constant pain since it stabs the wearer through the arm. The blackstone rune lets you planeshift between the material and shadow planes. Night extract is a liquid that darkens non-magical light around it when spilled.
* [[Shadow asp]], a poisonous snake from the plane of shadow that is often used as a guardian. They can become incorporeal, and their venom causes victims to come back as shadows.

* [[Spriggan]]
* [[Steel predator]], a predator from [[Acheron]] that looks like a robotic mix of a cat, a lizard, and a fish. They have a roar that inflicts sonic damage, and they are deaf, but more than make up for it with a great sense of smell and an ability to sense magic items that are made of metal, which they love to eat.
* [[Sunwyrm]], a shining [[dragon]] with brightly glowing wings, eight legs, and a ball of light on the tip of its tail. Their breath weapon is a beam of energy that only harms living things (radiation maybe?), and they can also transform their four front legs and teeth into energy weapons that pass through non-living matter and also change their whole body into an incorporeal form.
* [[Swarm]], any large swarm of monsters treated as one monster.
** Abyssal ant swarm, 8-inch long ants from the lower planes. Unlike other swarms they can be affected by mind affecting spells because the swarm shares a single mind. Their attacks do acid damage and penetrate as if they were +5 weapons.

* [[Thunder worm]], a colossal sized incorporeal giant worm that looks like a thunder cloud.

* [[Tunnel terror]], [[Gotcha Monster|a huge stony psionic worm with a hollow body that pretends to be the walls of a tunnel to trick prey into walking inside it]]. This book has a lot of giant worm monsters, doesn't it?
* [[Ulgurstasta]], a gargantuan inteligent undead maggot with many eyes created by [[Kyuss]]. Please no more worms! We have enough. Their stomach acid converts people they swallow or vomit on into skeletons, and their bodies are covered in 40-foot long tendrils that block nonmagical ranged weapon attacks and inflict slashing damage to everything around them.
* [[Varrangoin]], skull-faced poison-tailed bat people from the [[Abyss]]
** Acanist varrangoin, the leaders who have the abilities of wizards and are immune to low level spells

* [[Wendigo]] Template. The example is a 4th level human sorcerer.
* [[Wicker man]], a huge wooden construct used for capturing human sacrifices which are then burned alive inside of it. They are immune to magic except for a few spells that affect wood. Probably inspired by the movie, The Wicker Wan. This book did come out the same year as the terrible remake.
* [[Yellow Musk Creeper]]
* [[Yellow Musk Zombie]] template, the example is an orc.
* [[Yuan-ti]] Anathema, see page. Also include rules for items used by Anathemas. Blasphemous weapons have evil spirits bound into them and deal damage like an unholy weapon and inflict a ''blasphemy'' effect and also weaken good characters who try to wield them. A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices. Sickening weapons are unholy weapons that can also weaken good characters on a critical hit. Venomous fire is similar to alchemist's fire that also can do poison damage to what it burns.
* [[Yugoloth]]
** Piscoloth
** Skeroloth
* [[Yurian]], a crab like creature that walks around on two legs like a humanoid.
* [[Zodar]], a strange construct that looks like a suit of metal armor but is actually made of ceramic and muscle tissue. They almost never speak, but when they do everyone can understand them, and they also have an ability that works like the ''wish'' spell they can, but usually don't, use once per year. Nobody knows where they came from, but they sometimes join parties of adventurers.

===[[Prestige Class]]es:===
* [[Fiend of Blasphemy]], an evil outsider that leads a cult of minions who are magically bound to it and gains spells like an evil cleric.
* [[Fiend of Corruption]], an evil outsider who specializes in turning good mortals evil through temptation. They have abilities that let them give rewards to mortals who do evil, such as the fiendish grafts and symbionts later in this book.
* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings (except for the fiendish familiar), but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. They have no attacks without a host and cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small, evil-looking face that is grafted somewhere on a host's skin. They are completely helpless and immobile without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] containing its eggs. It lives in the host's digestive tract and improves the host's constitution, can protect them from poison, and gives the host rage like a barbarian, but also gives penalties to several checks and requires the host to eat extra food and lowers their endurance. It can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. Outside of a host it is harmless as it has no attacks and cannot forcefully enter a host.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fiend Folio

2020-07-15T05:41:52Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* Monsters */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

There is no saving throw for this curse, the ''remove curse'' spell is only partially effective and only has any effect if applied immediately, and the hound is impossible to harm in any way.

* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.
* [[Tirapheg]], an extremely weird monster with three heads, three eyes that are all on the same head with the third on the back of the head, three arms with the third growing from the chest, three fingers that are all on the middle arm, with the other two arms ending in blades, three legs, three toes all on the same legs, its mouth located on its chest under the middle arm, and three small tentacles between the middle arm and the mouth. Aside from the blades, the only body part it has two of are its ears, also on the middle head. It can make two illusionary copies of itself, but the illusions can do real damage if not recognized as illusions.
* [[Trilloch]], an invisible energy creature that feeds on the dying. They cannot directly harm anything, but they can make unintelligent creatures more aggressive and attacks become more accurate and damaging in their presence. The trilloch is impossible to harm, but can be driven away by ''dispel magic''.
* [[Troll]]
** Giant troll
** Giant two-headed troll
** Ice troll
** Spirit troll
* [[Tween]], an Ethereal creature that bonds to a host and appears as a shadowy copy of that host. It grants the host increased luck, but at the cost of giving bad luck to everyone around them. Possibly the monster with the stupidest name in the book.
* [[Umpleby]]
* [[Urchin]], sea urchins that can fire their spines as missiles and roll around on land. Inside of their bodies is a gemstone whose value depends on the type of urchin.
** Black urchin, the weakest and most common type.
** Green urchin, stronger and well camouflaged in water
** Red urchin, third strongest with venom that causes sleep
** Silver urchin, the strongest type with venom that causes a catatonic trance that can last for days.
** Yellow urchin, the second strongest type with venom that causes paralysis and is also well camouflaged in water.
* [[Vision]], an ethereal shadow creature that wants to be destroyed so it can return to its home plane so it attacks other creatures to get them to fight back. It cannot directly cause physical harm, but anybody who sees a vision has a chance of being affected by the illusion that they have suddenly aged ten years. When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.
* [[Vodyanoi]], a relative of the [[Umber Hulk]] that looks like a fish man instead of a bug. They lack the confusing gaze of an umber hulk, but can summon electric eels.
* [[Volt]], a floating ball of hair with bulging eyes, short horns, and a long tail. It bites people's necks to drain their blood and its tail shocks what it hits with electricity. Is this pokemon?
* [[Vortex]], a small sphere that generates a miniature tornado around itself.
* [[Whipweed]], a plant like tentacle monster with two long tentacles it attacks with and eight small legs it uses to move around. Does this sound familiar?
* [[Witherstench]], a hairless skunk like creature that produces a horrible smell constantly.
* [[Witherweed]], a plant with venom that drains dexterity and can cause seizures. It is weak against fire, but when it burns it produces smoke that can instantly kill people that inhale it.
* [[Xill]], a four armed monster reproduces by implanting eggs in humanoids xenomorph style. Seriously, we don't need anymore of these. They ambush their victim from the ethereal plane and attempt to either subdue or paralyze them with their venomous claws and grapple them and carry them back to the ethereal plane. They can be warded off with a ''protection from evil'' spell and it is extremely vulnerable while it is switching from the material plane to the ethereal and grappling a victim.
* [[Xvart]]
* [[Yellow musk creeper]], a plant that sprays victims with mind controlling dust from its flowers which lures them into the plant so it can drain their intelligence. If the victim dies from the intelligence drain, a new flower is added to the plant, but if the victim survives they become a yellow musk zombie.
* [[Yellow musk zombie]], a humanoid that has a yellow musk creeper seed implanted in their brain which allows the plant to control them. They can be restored back to normal using magic, but only if the plant that turned them is killed first. If not cured they will eventually die and grow into a new creeper.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.
* [[Darter]], a blood drinking lizard that can fire it fangs as darts that cause paralysis.
* [[Denzelian]]
* [[Gem dragon]]
** Amethyst dragon
** Crystal dragon
** Emerald dragon
** Sapphire dragon
** Topaz dragon
* [[Dune stalker]], now has a more reptilian appearance.
* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]
* [[Hellcat]]
* [[Ice lizard]]
* [[Iron cobra]]
* [[Khargra]]

** Fire mephit
** Ice mephit
** Lava mephit
** Mist mephit
** Smoke mephit

* [[Phantom stalker]]
* [[Quaggoth]]

* [[Scathe]], an ugly white reptilian humanoids\ related to the [[harrier]], that lives in icy regions. They have poisonous beaks and are immune to cold.
* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.
* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking. Especially considering how later 3.x edition Monster Manuals declined in quality, this book probably could've been released as just another Monster Manual.

They are slowly trying to take over the material plane and make it more like the far realm. They secret resin which they use to create homes and armor that protect them from the material plane, as well as weapons call ribbon daggers that are very sharp, but also flexible. They can only reproduce by turning humanoids into more kaorti.

* [[Ulgurstasta]], a gargantuan inteligent undead maggot with many eyes created by [[Kyuss]]. Please no more worms! We have enough. Their stomach acid converts people they swallow or vomit on into skeletons, and their bodies are covered in 40-foot long tendrils that block nonmagical ranged weapon attacks and inflict slashing damage to everything around them.

* [[Yellow Musk Zombie]] template, the example is an orc.
* [[Yuan-ti]] Anathema, see page. Also include rules for items used by Anathemas. Blasphemous weapons have evil spirits bound into them and deal damage like an unholy weapon and inflict a ''blasphemy'' effect and also weaken good characters who try to wield them. A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices. Sickening weapons are unholy weapons that can also weaken good characters on a critical hit. Venomous fire is similar to alchemist's fire that also can do poison damage to what it burns.

** Skeroloth
* [[Yurian]], a crab like creature that walks around on two legs like a humanoid.
* [[Zodar]], a strange construct that looks like a suit of metal armor but is actually made of ceramic and muscle tissue.

===[[Prestige Class]]es:===
* [[Fiend of Blasphemy]], an evil outsider that leads a cult of minions who are magically bound to it and gains spells like an evil cleric.

* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings (except for the fiendish familiar), but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.

* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. They have no attacks without a host and cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small, evil-looking face that is grafted somewhere on a host's skin. They are completely helpless and immobile without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] containing its eggs. It lives in the host's digestive tract and improves the host's constitution, can protect them from poison, and gives the host rage like a barbarian, but also gives penalties to several checks and requires the host to eat extra food and lowers their endurance. It can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. Outside of a host it is harmless as it has no attacks and cannot forcefully enter a host.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

There is no saving throw for this curse, the ''remove curse'' spell is only partially effective and only has any effect if applied immediately, and the hound is impossible to harm in any way. This probably was put into the book to give DMs a way to more easily kill off misbehaving player characters without having to resort to falling rocks or sending monsters that risk a TPK.

* [[Thoqqua]], a burning hot worm monster that tunnels through rock, like a smaller, fiery version of the [[Purple Worm]].

* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.

When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.

* [[Xvart]]
* [[Yellow musk creeper]], a plant that sprays victims with mind controlling dust from its flowers which lures them into the plant so it can drain their intelligence. If the victim dies from the intelligence drain, a new flower is added to the plant, but if the victim survives they become a yellow musk zombie.
* [[Yellow musk zombie]], a humanoid that has a yellow musk creeper seed implanted in their brain which allows the plant to control them. They can be restored back to normal using magic, but only if the plant that turned them is killed first. If not cured they will eventually die and grow into a new creeper.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.
* [[Darter]], a blood drinking lizard that can fire it fangs as darts that cause paralysis.
* [[Denzelian]]
* [[Gem dragon]]
** Amethyst dragon
** Crystal dragon
** Emerald dragon
** Sapphire dragon
** Topaz dragon
* [[Dune stalker]], now has a more reptilian appearance.
* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]
* [[Hellcat]]
* [[Ice lizard]]
* [[Iron cobra]]
* [[Khargra]]
* [[Mantari]], its stinger tail works differently now. It now has a venom that causes temporary strength and dexterity loss.
* Great Mantari, a larger variant.
* [[Mephit]]
** Fire mephit
** Ice mephit
** Lava mephit
** Mist mephit
** Smoke mephit
** Steam mephit
* [[Penanggalan]]
* [[Pernicon]]
* [[Phantom stalker]]
* [[Quaggoth]]
* [[Retriever]]
* [[Ruve]], an intelligent dog with psionic powers. Although they are lawful good, they are extremely arrogant and obnoxious.
* [[Scathe]], an ugly white reptilian humanoids\ related to the [[harrier]], that lives in icy regions. They have poisonous beaks and are immune to cold.
* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking. Especially considering how later 3.x edition Monster Manuals declined in quality, this book probably could've been released as just another Monster Manual.

They secret resin which they use to create homes and armor that protect them from the material plane, as well as weapons call ribbon daggers that are very sharp, but also flexible.

* [[Swarm]], any large swarm of monsters treated as one monster.

A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices.

* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings (except for the fiendish familiar), but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. They have no attacks without a host and cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small, evil-looking face that is grafted somewhere on a host's skin. They are completely helpless and immobile without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] containing its eggs. It lives in the host's digestive tract and improves the host's constitution, can protect them from poison, and gives the host rage like a barbarian, but also gives penalties to several checks and requires the host to eat extra food and lowers their endurance. It can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. Outside of a host it is harmless as it has no attacks and cannot forcefully enter a host.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fiend Folio

2020-07-15T05:07:15Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* Grafts and Symbionts */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.

Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.
* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books.

* [[Sunwyrm]], a shining [[dragon]] with brightly glowing wings, eight legs, and a ball of light on the tip of its tail. Their breath weapon is a beam of energy that only harms living things (radiation maybe?), and they can also transform their four front legs and teeth into energy weapons that pass through non-living matter and also change their whole body into an incorporeal form.
* [[Swarm]], any large swarm of monsters treated as one monster.

* [[Ulgurstasta]], a gargantuan inteligent undead maggot with many eyes created by [[Kyuss]]. Please no more worms! We have enough. Their stomach acid converts people they swallow or vomit on into skeletons, and their bodies are covered in 40-foot long tendrils that block nonmagical ranged weapon attacks and inflict slashing damage to everything around them.

* [[Yuan-ti]] Anathema, see page. Also include rules for items used by Anathemas. Blasphemous weapons have evil spirits bound into them and deal damage like an unholy weapon and inflict a ''blasphemy'' effect and also weaken good characters who try to wield them. A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices. Sickening weapons are unholy weapons that can also weaken good characters on a critical hit. Venomous fire is similar to alchemist's fire that also can do poison damage to what it burns.

** Skeroloth
* [[Yurian]], a crab like creature that walks around on two legs like a humanoid.

Nobody knows where they came from, but they sometimes join parties of adventurers.

===[[Prestige Class]]es:===
* [[Fiend of Blasphemy]], an evil outsider that leads a cult of minions who are magically bound to it and gains spells like an evil cleric.

* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings (except for the fiendish familiar), but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

There is no saving throw for this curse, the ''remove curse'' spell is only partially effective and only has any effect if applied immediately, and the hound is impossible to harm in any way.

If they succeed, the sheet phantom merges with the corpse and becomes a sheet ghoul. Seriously, how old was the person who designed who designed the sheet phantom and sheet ghoul? 5 maybe?

* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.

When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.
* [[Vodyanoi]], a relative of the [[Umber Hulk]] that looks like a fish man instead of a bug. They lack the confusing gaze of an umber hulk, but can summon electric eels.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.

** Emerald dragon
** Sapphire dragon

* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]
* [[Hellcat]]

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.
* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking.

* [[Fiend of Blasphemy]], an evil outsider that leads a cult of minions who are magically bound to it and gains spells like an evil cleric.
* [[Fiend of Corruption]], an evil outsider who specializes in turning good mortals evil through temptation. They have abilities that let them give rewards to mortals who do evil, such as the fiendish grafts and symbionts later in this book.
* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fiend Folio

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* Monsters */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

There is no saving throw for this curse, the ''remove curse'' spell is only partially effective and only has any effect if applied immediately, and the hound is impossible to harm in any way. This probably was put into the book to give DMs a way to more easily kill off misbehaving player characters without having to resort to falling rocks or sending monsters that risk a TPK.

They can only be damaged by silver and magic weapons, and can only be damaged by holy water while it is trying to merge with a human.

* [[Terithran]], a humanoid from the ethereal plane. Casting powerful magic other than cleric or druid magic on the material plane close to its layer on the ethereal plane makes it angry, and it will try to kidnap and punish the magic user responsible.
* [[Thoqqua]], a burning hot worm monster that tunnels through rock, like a smaller, fiery version of the [[Purple Worm]].

* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.
* [[Tirapheg]], an extremely weird monster with three heads, three eyes that are all on the same head with the third on the back of the head, three arms with the third growing from the chest, three fingers that are all on the middle arm, with the other two arms ending in blades, three legs, three toes all on the same legs, its mouth located on its chest under the middle arm, and three small tentacles between the middle arm and the mouth.

When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.
* [[Vodyanoi]], a relative of the [[Umber Hulk]] that looks like a fish man instead of a bug. They lack the confusing gaze of an umber hulk, but can summon electric eels.

* [[Vortex]], a small sphere that generates a miniature tornado around itself.
* [[Whipweed]], a plant like tentacle monster with two long tentacles it attacks with and eight small legs it uses to move around. Does this sound familiar?
* [[Witherstench]], a hairless skunk like creature that produces a horrible smell constantly.
* [[Witherweed]], a plant with venom that drains dexterity and can cause seizures. It is weak against fire, but when it burns it produces smoke that can instantly kill people that inhale it.

They ambush their victim from the ethereal plane and attempt to either subdue or paralyze them with their venomous claws and grapple them and carry them back to the ethereal plane. They can be warded off with a ''protection from evil'' spell and it is extremely vulnerable while it is switching from the material plane to the ethereal and grappling a victim.
* [[Xvart]]
* [[Yellow musk creeper]], a plant that sprays victims with mind controlling dust from its flowers which lures them into the plant so it can drain their intelligence. If the victim dies from the intelligence drain, a new flower is added to the plant, but if the victim survives they become a yellow musk zombie.
* [[Yellow musk zombie]], a humanoid that has a yellow musk creeper seed implanted in their brain which allows the plant to control them. They can be restored back to normal using magic, but only if the plant that turned them is killed first. If not cured they will eventually die and grow into a new creeper.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.
* [[Darter]], a blood drinking lizard that can fire it fangs as darts that cause paralysis.
* [[Denzelian]]
* [[Gem dragon]]
** Amethyst dragon
** Crystal dragon
** Emerald dragon
** Sapphire dragon
** Topaz dragon
* [[Dune stalker]], now has a more reptilian appearance.
* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]
* [[Hellcat]]
* [[Ice lizard]]
* [[Iron cobra]]
* [[Khargra]]
* [[Mantari]], its stinger tail works differently now. It now has a venom that causes temporary strength and dexterity loss.
* Great Mantari, a larger variant.
* [[Mephit]]
** Fire mephit
** Ice mephit
** Lava mephit
** Mist mephit
** Smoke mephit
** Steam mephit
* [[Penanggalan]]
* [[Pernicon]]
* [[Phantom stalker]]
* [[Quaggoth]]
* [[Retriever]]
* [[Ruve]], an intelligent dog with psionic powers. Although they are lawful good, they are extremely arrogant and obnoxious.
* [[Scathe]], an ugly white reptilian humanoids\ related to the [[harrier]], that lives in icy regions. They have poisonous beaks and are immune to cold.
* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.

* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking. Especially considering how later 3.x edition Monster Manuals declined in quality, this book probably could've been released as just another Monster Manual.

They secret resin which they use to create homes and armor that protect them from the material plane, as well as weapons call ribbon daggers that are very sharp, but also flexible.

* [[Swarm]], any large swarm of monsters treated as one monster.

* [[Yuan-ti]] Anathema, see page. Also include rules for items used by Anathemas. Blasphemous weapons have evil spirits bound into them and deal damage like an unholy weapon and inflict a ''blasphemy'' effect and also weaken good characters who try to wield them. A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices. Sickening weapons are unholy weapons that can also weaken good characters on a critical hit. Venomous fire is similar to alchemist's fire that also can do poison damage to what it burns.

* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fiend Folio

2020-07-15T04:47:47Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* Monsters */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

==1st Edition==

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.

Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.

** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.
* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking.

They secret resin which they use to create homes and armor that protect them from the material plane, as well as weapons call ribbon daggers that are very sharp, but also flexible.

* [[Yuan-ti]] Anathema, see page. Also include rules for items used by Anathemas. Blasphemous weapons have evil spirits bound into them and deal damage like an unholy weapon and inflict a ''blasphemy'' effect and also weaken good characters who try to wield them. A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices. Sickening weapons are unholy weapons that can also weaken good characters on a critical hit. Venomous fire is similar to alchemist's fire that also can do poison damage to what it burns.

* [[Fiend of Blasphemy]], an evil outsider that leads a cult of minions who are magically bound to it and gains spells like an evil cleric.

* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fiend Folio

2020-07-15T04:25:15Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* Monsters */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

If they succeed, the sheet phantom merges with the corpse and becomes a sheet ghoul. Seriously, how old was the person who designed who designed the sheet phantom and sheet ghoul? 5 maybe?

* [[Tabaxi]]
* [[Tentamort]] a spherical creature with short suckered tentacles on one side of its body it uses to move around and two much longer tentacles on the other side it uses to attack.

* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.

** Giant two-headed troll
** Ice troll

When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.
* [[Vodyanoi]], a relative of the [[Umber Hulk]] that looks like a fish man instead of a bug. They lack the confusing gaze of an umber hulk, but can summon electric eels.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.

** Emerald dragon
** Sapphire dragon

* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.
* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking.

** Skeroloth
* [[Yurian]], a crab like creature that walks around on two legs like a humanoid.
* [[Zodar]], a strange construct that looks like a suit of metal armor but is actually made of ceramic and muscle tissue. They almost never speak, but when they do everyone can understand them, and they also have an ability that works like the ''wish'' spell they can, but usually don't, use once per year. Nobody knows where they came from, but they sometimes join parties of adventurers.

===[[Prestige Class]]es:===
* [[Fiend of Blasphemy]], an evil outsider that leads a cult of minions who are magically bound to it and gains spells like an evil cleric.
* [[Fiend of Corruption]], an evil outsider who specializes in turning good mortals evil through temptation. They have abilities that let them give rewards to mortals who do evil, such as the fiendish grafts and symbionts later in this book.
* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Therianthrope

2020-07-15T04:15:55Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* D&D Therianthropes */

{{stub}}

'''Therianthrope''' is a scientific(ish) term thrown around to serve as a general placeholder for the vast array of monsters who boil down to "people who can change into animal form". Like, you're familiar with the [[werewolf]]? Replace "wolf" with literally any other animal, and you've got the therianthrope in a nutshell. The term is also used to cover an array of animal shapeshifters who aren't "were(insert species here)", from D&D's "Beastweres"/"Antherions" (sapient animals who can take on humanoid forms, in other words reverse-werewolves) to mythical creatures like the [[Hengeyokai]] and [[Selkie]].

==D&D Therianthropes==
[[Dungeons & Dragons]] has a truly massive array of the things, which [[Pathfinder]] has shamelessly followed up on. In D&D, they're actually called "Lycanthropes", but that's actually the formal name for [[werewolf]], so we just use the term "werebeast" or "therianthrope" The most iconic D&D therianthropes are [[Werebear]]s, [[Wereboar]]s, [[Wererat]]s and [[Weretiger]]s, but a list of other were-beasts that appeared in 2nd edition alone would include:
* [[Werebadger]] (mostly dwarven in origin)
* [[Werebat]]
* [[Werecrocodile]]
* [[Song Dragon|Weredragon]] (technically a form of "animal bride"; an all-female race of dragons who can assume human shape and breed with human men to propagate)
* [[Werefox]] (an all-female race of elven therianthropes; even non-elven women who get infected will change to look like elves in their human form)
* [[Werehyena]]
* [[Werejackal]] (in default and [[Ravenloft]] flavors).
** There is also a monster called a [[Jackalwere]] which is like a reverse werejackal, as its true form is its animal form instead of its humanoid form. Their bite does not spread therianthropy, and they strangely have the ability to put victims to sleep with their gaze.
* [[Werejaguar]] (in default, [[Mystara]] and Ravenloft flavors)
* [[Wereleopard]]
* [[Werelion]]
* [[Werepanther]]
* [[Wereraven]]
* [[Wereray]] (as in were-manta/stingray)
* [[Wereshark]] (in default and Ravenloft flavors)
* [[Werespider]]
* [[Wereswine]]
* [[Seawolf]]

And because that wasn't enough, [[Ravenloft]] fans invented [[Werealligator]]s, [[Werebaboon]]s, [[Werecheetah]]s, [[Werecobra]]s (in normal and spitting varieties), [[Weremustela]] (in ermine, mink, polecat, and weasel flavors), [[Werepossum]]s, [[Wereraccoon]]s, and [[Werewolverine]]s!

The [[Forgotten Realms]] setting introduced a wide number of therianthropes, almost as many as [[Ravenloft]], although a significant portion of these were benevolent werebeasts who thusly received little information beyond the fact that they exist. This list includes Wereapes, Werebison, Werecats, Weredogs, Weredolphins, Wereowls, Werepegasi, Werewyverns and Werecougars. Many of these creatures made their appearance in the [[Advanced Dungeons & Dragons]] 2nd edition splatbook "Hall of Heroes".

Because D&D is a setting where [[giant]]s exist alongside normal humanoids, inevitably, somebody began to wonder: can giants be affected by the different therianthropy strains? This got an official answer in the Dragon Bestiary article for [[Dragon Magazine]] #266, which provided the following giant species vs. therianthrope srain breakdown, and also provided stats for the two species of "true giant therianthrope"; the Polarwere (a [[Frost Giant]] [[Werebear]]) and the Shadkyn ([[Voadkyn]] [[Werebat]]). All giants not mentioned on this list are immune to all forms of therianthropy.
* Cyclopskin: All therianthrope strains
* [[Cyclops]]: Usually [[werebear]] or [[werebat]], but cannot contract [[werefox]], [[weretiger]], [[seawolf]] or "any of the more exotic types". Cyclops therianthropes only have giant and hybrid forms.
* [[Desert Giant]]: Their slow petrification curse makes them immune to therianthropy.
* [[Ettin]]: Can only become [[werewolves]], [[wererat]]s and [[wereboar]]s, can only assume a 2-headed hybrid form.
* [[Firbolg]]: All strains except [[Wereraven]].
* [[Fomorian]]: Immune to therianthropy.
* [[Fog Giant]]: Immune to therianthropy.
* [[Frost Giant]]: [[Werebear]] and [[Seawolf]].
* [[Hill Giant]]: All strains except [[Wereraven]], most commonly [[werewolf]], [[wereboar]], [[wererat]], and [[werebat]].
* [[Jungle Giant]]: All strains native to the jungle, specifically [[werefox]], [[werebat]] and [[werecat]] - feline therianthropy is incredibly common amonst jungle giants.
* [[Stone Giant]]: Immune to therianthropy.
* [[Verbeeg]]: All strains except [[Wereraven]].
* [[Voadkyn]]: All strains.

Third Edition allows ''any'' animal to have werecreatures if there's a humanoid or giant type within one size category of the animal.

===Playing Werebeasts in D&D===
====BECMI Werebeast Classes====
Most subsequent editions of [[Dungeons & Dragons]] would forbid PCs playing a therianthrope; the power differential is just too great to be balanced. BECMI was not afraid to get crazy. Thusly, the fourth and last of its [[Creature Crucible]] series, ''Night Howlers'', focused on introducing an array of therianthrope race-classes, all of which shared the same following rules:

::The following BECMI Werebeast Classes exist: [[Werebat]], [[Wereboar]], [[Werefox]], [[Wererat]], [[Selkie|Wereseal]], [[Wereshark]], [[Weretiger]], [[Werewolf]], [[Wereswine]].
::Except for Werefoxes and Wereswine, who use [[Intelligence]] instead, all Werebeasts treat [[Strength]] as their prime requisite when in werebeast form.
::Being a therianthrope is a form of [[multiclassing]]; XP earned in werebeast form is tracked separately to that earned in human form. Thusly, a therianthrope can reach 36th level in their chosen race-class, as well as in their original class, but they will need to adventure sufficiently in the form of a beast to do so.
:::Nothing is mentioned as to whether the Beast-Man Form affects this EXP gaining.
::A therianthrope has access to their original class abilities in human form, and to beast abilities in beast form.
::Assuming beast form applies a number of racial ability modifiers unique to a given werebeast strain. These modifiers only apply in beastform - and, for [[Charisma]], apply only when interacting with animals or werebeasts of the same species.
::All therianthropes have natural armor in their beast and beast-man forms, but they can commission special armor designed to fit either their humanoid forms (human and beast-man) or their beast forms (which somebody with hands will need to put on them). In this case, use the superior AC value.
::In combat, a therianthrope that has reached a level higher than 8th counts as having +1HD per 2 levels over 8th (+1 at 10th, +2 at 12, etc) ''for combat purposes only''.
::Therianthropes have different hit points between their bestial and human forms, which are tracked separately. A therianthrope can only die if reduced to 0 hit points in the form with the ''larger'' hit point total; if reduced to 0 HP in the form with the ''smaller'' hit poitn total, it is forced into that other form.
::In beast form, therianthropes save as [[Fighter]]s at a level equal to their Hit Dice. Upon gaining maximum Hit Dice for their weretype, they may apply the ''higher'' of either their Hit Dice or their therianthrope experience level to the Fighter Saving Throws Table to determine their saves. Damage received in one form remains when the therianthrope changes to its second form.
::All Therianthropes gain 9 special abilities shared in common across all the breeds, as well as a 10th ability unique to their breed, as they level up. Which abilities are gained at which level depends on the species. See the table below for the common special abilities.
::At 9th level, all therianthropes gain access to their Beast-Man form. In this form, a therianthrope has access to '''all''' of their special abilities from '''both''' their beast form ''and'' their human form. In this form, they use their beast-form HP pool, and they use the better of their saves between their beast-form saves and their human-form saves. They can attack with weapons or their natural attacks, cast spells, and optionally may either gain the benefits of the beast form's ability score modifiers, and/or from 20th level may only apply ''positive'' ability score modifiers from their beast form when in hybrid form.
::Therianthropes touched by Wolfsbane suffer the effects of a Cause Fear spell that lasts for 2 turns, requiring a Save vs. Poison to avoid fleeing. This applies in all forms, and even in human form, the therianthrope uses its beast-form saves, regardless of if these are worse.
::Silver weapons always do normal damage to a therianthrope. Even in human form, touching silver for more than 1 turn requires a Save vs. Poison (beast-form saves) to avoid breaking out in a painful rash.

{| class=wikitable
!Werebeast Ability Number ||Werebeast Ability Description
|-
|I ||''Must'' take beast form on the nights of, preceding and following the full moon. Can voluntarily transform at night if the moon is visible.
|-
|II ||Normal weapons do 1/2 damage (round up). Can voluntarily transform at night without needing the moon.
|-
|III ||Can speak with other therianthropes and creatures of own weretype while in beast form.
|-
|IV ||Can voluntarily transform whenever desired.
|-
|V ||Normal weapons do 1/4 damage (round up).
|-
|VI ||Immune to normal weapons when in beast or beast-man form.
|-
|VII ||Can summon 1d2 animals of own weretype, which will arrive in 1d4 rounds (if in immediate vicinity) or 1d4 turns (if in the general area). This increases to 1d4 at 2nd level, 1d6 at 4th level, 1d8 at 6th level, and 1d10 at 8th level. Every four levels thereafter, add +1d10 to the animals summoned.
|-
|VIII ||Can recover 1d4+1 hit points for every full 24 hours of rest spent in wereform, increasing by +1 for every 3 additional levels.
|-
|IX ||Can now summon therianthropes of own weretype when summoning animals; the total remains unchanged from Ability VII, with DM determining how many are normal and how many are werebeasts.
|}

{{D&D1e-Races}}

====AD&D Werebeasts====
A draft attempt at making werebeasts into a playable race was seen in the [[Ravenloft]] [[Netbook]] titled [[Books of S|"The Book of Sorrows"]], which took its inspiration from official rules first seen in the boxed set ''Requiem: The Grim Harvest'', which allowed players to play various [[undead]] monsters.

{{D&D2e-Races}}

==Pathfinder Therianthropes==
The 3e ability to apply the template to anything was kept in [[Pathfinder]]. Weresharks were canonically introduced in the Skull and Shackles [[Adventure Path]].

The Pathfinder werebeast list consists of the following monsters:
* Silverblood Werewolf - A variant [[werewolf]] with immunity to silver, but who weakens and often dies as the moon waxes.
* Werebat
* Werebear
* Wereboar
* Werecrocodile
* Wereraptor - No, not a were[[dinosaur]], a were-eagle or hawk.
* Wererat
* Wereshark
* Weretiger
* Werewolf

In its Bestiary 6, Pathfinder also introduced the '''Entothrope''' template, a variant of the standard Lycanthrope template that allows for the existence of werebugs. Three entothropes were statted; the Weremantis, Werespider, and Werewasp.

==World of Darkness Therianthropes==
In the [[World of Darkness]], both [[Werewolf: The Apocalypse]] and [[Werewolf: The Forsaken]] have included therianthropic player's options ranging from Weresharks to Wereravens to Wereboars.... and so on.

==Monster Hunter International Therianthropes==
In [[Monster Hunter International]] werecreatures almost all become crazed killer beasts. The few exceptions put themselves through hell to control it, used an ancient artifact, or were high functioning crazed killers before the transformation and managed to coax the urges into a symbiotic relation. The one exception is weredolphins who are actually friendly, which is surprising given how sick and twisted ''normal'', real world dolphins are... but then, they've got great publicity, which is why they tend to be portrayed as Good aligned in fantasy games and books.

Gotcha Monster

2020-07-15T04:08:08Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* D&D Gotcha Monsters */

{{dnd-stub}}
{{NeedsImages}}

'''Gotcha Monster''' is a slang term used in /tg/ circles to refer to any of the wide array of monsters whose hunting strategy revolves around disguising themselves or lurking in seemingly innocuous places and then trying to kill [[adventurer]]s the moment that they let their guard down even the slightest. The term is most associated with [[Advanced Dungeons & Dragons]] and [[Old School Roleplaying]], which gave rise to some of the most infamous species of Gotcha Monsters in existence, but the basic idea can be found pretty much throughout gaming circles.

Some also argue that monsters which do not directly attack players, but damage their combat abilities in some way, such as [[Rust Monster]]s and [[Disenchanter]]s, also count as Gotcha Monsters.

A [[Game Master]] who relies on using Gotcha Monsters to excess is known as a [[Killer Game Master]]. Or else as a dick.

==D&D Gotcha Monsters==
Aside from [[slime]]s, [[golem]]s, [[therianthrope]]s and [[shadow]]s, which can easily be portrayed in this way, D&D has a ''long'' list of Gotcha Monsters.

Animated Object: Could be a table, a chair, or just about anything in the room waiting to surprise you.

Brain Mole: An ordinary mole that happens to feed on mental energy, resulting in it draining away memories and potentially leaving its victims as drooling vegetables if they get too close to its den.

[[Cloaker]]: A killer manta ray that disguises itself as a cloak to trick people into wearing it, which lets it eat them.

Gas Spore: A floating puffball [[fungus]] that disguises itself as a [[Beholder]]; when burst by a spear or arrow, it explodes in a shower of lethally poisonous spores.

Cushion Fungi: Carnivorous fungi that look like pillows so people will sleep on them.

Shrieker: Mushrooms that scream really loudly and attract other monsters to you if you disturb them.

[[Gargoyle]]: A vicious predatory creature that disguises itself as a statue in order to attack prey when their guard is down.

Ear Seeker: A wood-eating insect that often infests dungeons doors, and will bore into the ears of anyone who tries to listen at those doors, because they like to lay their eggs in the ear canals of humanoids so their larvae can feed on living brain tissue.

Throat Leech: A small leech that infests ponds and streams, and which prefers to feed by swimming down the throat of anyone drinking the water so it can attach itself to the inside of the throat and suck their blood, incidentally suffocating them as it swells up.

Living Wall: A mass of undead flesh and bone melded together, which uses innate illusions to disguise itself as an ordinary stone wall until something living comes close, whereupon it tries to rip them apart and absorb them into its mass.

Lurker: A flattish monster, somewhere between a [[slime]] and a flying manta ray, that clings to the ceiling and then drops on people to smother them.

Trapper: A bigger version of the Lurker, which disguises itself as a dungeon or cavern floor and then rises up to crush and devour anyone who steps on it.

Miner: A forest-dwelling variant of the Trapper, which hides itself on forest trails and waits until victims step on its back, stabbing themselves on its numerous paralytic poison-carrying quills so it can then smother and devour them.

Giant Black Squirrel: A 2ft-long, black-furred relative of the squirrel that inhabits "evil-dominated forests". Harmless, but likes to steal valuables from travelers.

[[Mimic]]: A predatory [[slime]]-like creature which disguises itself as an inanimate object to lure in humanoid victims.

Piercer: A carnivorous gastropod which resembles a stalactite; it clings to cavern ceilings and then attempts to drop on anything that moves below, hoping to fatally impale them on its sharpened shell

Choke Creeper: A predatory vine-like plant that drapes itself across tree branches, and attempts to strangle any animal that gets within range.

[[Roper]]: A tentacled monster that disguises itself as a rock outcropping, boulder or stalagmite until victims get within range.

[[Rust Monster]]: A giant beetle-like creature that feeds on metal, dissolving arms and armor in pursuit of food.

Heway: An intelligent snake which hunts by climbing into wells or ponds and then shedding its skin, which transmutes the water into a toxic fluid; it then eats anything killed by drinking the fouled water.

[[Treant]]: An intelligent tree which will rip you to pieces if it thinks you're destroying the forest. Fortunately, they're technically good guys, so you won't usually need to fight them.

Rot Grub: Voracious predatory maggots which infest mounds of dung and carrion, and which will leap to infest and devour living creatures that get too close.

Adherer: A monstrous humanoid which looks like a mummy, but which is actually a living being covered in fibrous skin-strands that secrete a gluey resin. They use these to catch an adventurer's weapon and rip it out of his grasp, whereupon they can beat him to death.

Disenchanter: A creature resembling a blue camel with an elephant's trunk that sucks the magical energy out of magic items.

Gambado: A predatory monster that hides itself in a pit with just its head - covered in a seemingly abandoned skull - poking out. It then jumps out and tries to kill anyone who gets too close.

Sheet Phantom: A malevolent undead which possesses a thick blanket and uses it as a physical body to try and grapple, trap and smother living beings.

Stunjelly: A variant of the Gelatinous Cube which clings to a single section of stone wall and paralyzes anyone who touches it. Then it oozes over their body and eats them.

Yellow Musk Creeper: A pretty creeping vine with beautiful yellow flowers. It lures victims in with its sweet scent, and then plants seeds in their heads, which consume the host's brain and then hijack the body as a [[zombie]] they pilot to find a new place to grow.

Aballin: A [[slime]]-like creature that resembles a mass of animate water, which it pretends to be before drowning and digesting anything that attempts to drink from it.

Carrionette: A sapient, malicious marionette-type puppet that possesses independent motion and a malicious desire to kill people.

Lock Lurker: A vicious invertebrate that resembles a gold coin, until it extends its legs and the lethally poisonous, scorpion-like stinging tail it normally hides in the [[Ethereal Plane]].

Noran: A malevolent version of the Treant which lurks in underground environments.

Bloodring: A blood-drinking parasitic worm that disguises itself by pretending to be an enchanted ring, as it can extend its own innate magic resistance to any creature it is touching.

Goldbug: A blood-sucking beetle that disguises itself as a gold coin to get close to its humanoid prey.

Wizard Lice: Blood-sucking insects that would be merely annoying if they didn't strip the spells right out of the minds of spellcaster hosts.

Vampire Moss: A mass of hanging, dense moss which passively drains the life force from any living creature that gets within 10 yards.

Heart Tick: An oversized tick that latches onto victims with its barbed legs so it can puncture their heart and siphon out the richest, most potent blood in their body.

Dark Tree: A malevolent counterpart to the Treant.

Singing Tree: Another malevolent counterpart to the Treant, which uses hypnotically alluring songs to bring victims closer.

Xaver: A ferrovorous creature which disguises itself as a sword in order to get closer to unprotected metal.

Chaos Imp: An annoying [[imp]] subspecies native to [[Limbo]], which can "possess" inanimate matter and reshape it to their will, which they use to play potentially deadly pranks.

Living Web: A [[slime]]-like entity that disguises itself as a mass of abandoned cobwebs, then engulfs and electrocutes anything that touches it so it can consume them.

Wolf-in-Sheep's-Clothing: It doesn't look like a Sheep, and it isn't a wolf either. It looks like a small rabbit like creature, but that is only a small lure on top of its body, which looks more a tree stump.

Umbral Blot (Black ball): A construct with the appearance and properties of a [[Sphere of Annihilation]]. This might not be the best disguise since a Sphere of Annihilation isn't something you should be messing with anyway.

Genius Loci: A living, malevolent piece of landscape.

Boneleaf: An aberration that resembles a plant. It is intelligent and can use illusions lure prey. All boneleaves in an area are actually parts of a single organism so what one learns, all boneleaves nearby also learn.

Eye of the Deep: A relative of [[Beholder]]s that like to fool people at sea with illusions of things like mermaids.

[[Dusanu]]: It looks like a [[Skeleton]], but it actually is a [[Fungus]] that animates bones and not an undead and so doesn't have their weaknesses and it is also infectious.

[[Spanner]]: An animated stone bridge that can talk and can throw you off or open a hole in itself to make you fall, so be polite.

[[Slime|Symbiotic Jelly]]: An ooze that partners with another monster and uses illusions to make the monster look like something less dangerous and lures in prey for the monster with illusions of things that they want such as treasure.

* Tunnel terror: A huge stony psionic worm with a hollow body that pretends to be the walls of a tunnel to trick prey into walking inside it.

[[Creed]]: CREEEEEEEEEEEEEED!!! Wait no, that's 40k.

[[Gazebo]]: Beware the dread gazebo.

== Real Life Gotcha Monsters ==

To some extent, ''almost every'' [[Wikipedia:ambush predator|ambush predator]] is a "Gotcha Monster". Just to name a few types:

* You have your "aggressive mimics", who pretend to be something edible, and turn around and eat those who would it it; for example, looking like a flower, and grabbing pollinators who show up, or the "alligator snapping turtle", whose tongue resembles a worm.
* There's trap-making animals, such as the antlion or web-making spiders.
* And then there's the camouflage and stealth approach, of which some varieties of [[cats]] are a common example.

Easily the most likely one a D&D player is going to run into though are crocodiles and alligators thanks to the combination of the old 'look like a log' trick and being a credible threat to people in armor, like most adventurers.

Fiend Folio

2020-07-15T04:07:07Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* Monsters */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

==1st Edition==
* [[Aarakocra]]
* [[Achaierai]] a giant evil bird with a spherical body with no neck and tiny wings and four long metallic legs it attacks with. They can release poison smoke when badly injured. This should give you a good idea of the kinds of monsters that are to follow.
* [[Adherer]], a weird creature that looks like a mummy but sweats glue.
* [[Alaex]], a personification of a god's anger that resembles a duplicate of the person it has been sent to punish.
* [[Algoid]], a humanoid that actually is a colony of intelligent algae. They can use mind blast and can control trees like a [[treant]]. They are immune to psionic attacks, edged weapons of less than +2 quality, fire, and electricity, but take damage from some spells that affect water.
* [[Al-mi'raj]], a killer rabbit with a unicorn's horn.
* [[Apparition]], an undead that cannot cause physical harm, so it tries to scare people to death.
* [[Assassin bug]], giant flies that attack humans in male/female pairs. The male paralyzes the victim so that the female can lay their eggs in their wounds.
* [[Astral searcher]], a spirit formed from violent thoughts that attacks people psychically to destroy their mind to it can posses their body.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.

* [[Apparition]]

Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.

* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]

* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books.

A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices.

* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fiend Folio

2020-07-15T04:06:12Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* Monsters */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.

* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.
* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books.

* [[Wendigo]] Template. The example is a 4th level human sorcerer.
* [[Wicker man]], a huge wooden construct used for capturing human sacrifices which are then burned alive inside of it. They are immune to magic except for a few spells that affect wood. Probably inspired by the movie, The Wicker Wan.
* [[Yellow Musk Creeper]]
* [[Yellow Musk Zombie]] template, the example is an orc.
* [[Yuan-ti]] Anathema, see page. Also include rules for items used by Anathemas. Blasphemous weapons have evil spirits bound into them and deal damage like an unholy weapon and inflict a ''blasphemy'' effect and also weaken good characters who try to wield them. A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices. Sickening weapons are unholy weapons that can also weaken good characters on a critical hit. Venomous fire is similar to alchemist's fire that also can do poison damage to what it burns.
* [[Yugoloth]]
** Piscoloth
** Skeroloth
* [[Yurian]], a crab like creature that walks around on two legs like a humanoid.
* [[Zodar]], a strange construct that looks like a suit of metal armor but is actually made of ceramic and muscle tissue. They almost never speak, but when they do everyone can understand them, and they also have an ability that works like the ''wish'' spell they can, but usually don't, use once per year. Nobody knows where they came from, but they sometimes join parties of adventurers.

===[[Prestige Class]]es:===
* [[Fiend of Blasphemy]], an evil outsider that leads a cult of minions who are magically bound to it and gains spells like an evil cleric.
* [[Fiend of Corruption]], an evil outsider who specializes in turning good mortals evil through temptation. They have abilities that let them give rewards to mortals who do evil, such as the fiendish grafts and symbionts later in this book.
* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fiend Folio

2020-07-15T03:58:22Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* Prestige Classes: */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

There is no saving throw for this curse, the ''remove curse'' spell is only partially effective and only has any effect if applied immediately, and the hound is impossible to harm in any way. This probably was put into the book to give DMs a way to more easily kill off misbehaving player characters without having to resort to falling rocks or sending monsters that risk a TPK.

* [[Terithran]], a humanoid from the ethereal plane. Casting powerful magic other than cleric or druid magic on the material plane close to its layer on the ethereal plane makes it angry, and it will try to kidnap and punish the magic user responsible.
* [[Thoqqua]], a burning hot worm monster that tunnels through rock, like a smaller, fiery version of the [[Purple Worm]].

* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.
* [[Tirapheg]], an extremely weird monster with three heads, three eyes that are all on the same head with the third on the back of the head, three arms with the third growing from the chest, three fingers that are all on the middle arm, with the other two arms ending in blades, three legs, three toes all on the same legs, its mouth located on its chest under the middle arm, and three small tentacles between the middle arm and the mouth.

** Giant two-headed troll
** Ice troll
** Spirit troll

When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.
* [[Vodyanoi]], a relative of the [[Umber Hulk]] that looks like a fish man instead of a bug. They lack the confusing gaze of an umber hulk, but can summon electric eels.

* [[Vortex]], a small sphere that generates a miniature tornado around itself.
* [[Whipweed]], a plant like tentacle monster with two long tentacles it attacks with and eight small legs it uses to move around. Does this sound familiar?
* [[Witherstench]], a hairless skunk like creature that produces a horrible smell constantly.
* [[Witherweed]], a plant with venom that drains dexterity and can cause seizures. It is weak against fire, but when it burns it produces smoke that can instantly kill people that inhale it.

They ambush their victim from the ethereal plane and attempt to either subdue or paralyze them with their venomous claws and grapple them and carry them back to the ethereal plane. They can be warded off with a ''protection from evil'' spell and it is extremely vulnerable while it is switching from the material plane to the ethereal and grappling a victim.
* [[Xvart]]
* [[Yellow musk creeper]], a plant that sprays victims with mind controlling dust from its flowers which lures them into the plant so it can drain their intelligence. If the victim dies from the intelligence drain, a new flower is added to the plant, but if the victim survives they become a yellow musk zombie.
* [[Yellow musk zombie]], a humanoid that has a yellow musk creeper seed implanted in their brain which allows the plant to control them. They can be restored back to normal using magic, but only if the plant that turned them is killed first. If not cured they will eventually die and grow into a new creeper.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.
* [[Darter]], a blood drinking lizard that can fire it fangs as darts that cause paralysis.
* [[Denzelian]]
* [[Gem dragon]]
** Amethyst dragon
** Crystal dragon
** Emerald dragon
** Sapphire dragon
** Topaz dragon
* [[Dune stalker]], now has a more reptilian appearance.
* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.

They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.

* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking. Especially considering how later 3.x edition Monster Manuals declined in quality, this book probably could've been released as just another Monster Manual.

* [[Swarm]], any large swarm of monsters treated as one monster.

A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices.

* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fiend Folio

2020-07-15T03:55:36Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* 1st Edition */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

==1st Edition==
* [[Aarakocra]]
* [[Achaierai]] a giant evil bird with a spherical body with no neck and tiny wings and four long metallic legs it attacks with. They can release poison smoke when badly injured. This should give you a good idea of the kinds of monsters that are to follow.
* [[Adherer]], a weird creature that looks like a mummy but sweats glue.
* [[Alaex]], a personification of a god's anger that resembles a duplicate of the person it has been sent to punish.
* [[Algoid]], a humanoid that actually is a colony of intelligent algae. They can use mind blast and can control trees like a [[treant]]. They are immune to psionic attacks, edged weapons of less than +2 quality, fire, and electricity, but take damage from some spells that affect water.
* [[Al-mi'raj]], a killer rabbit with a unicorn's horn.
* [[Apparition]], an undead that cannot cause physical harm, so it tries to scare people to death.
* [[Assassin bug]], giant flies that attack humans in male/female pairs. The male paralyzes the victim so that the female can lay their eggs in their wounds.
* [[Astral searcher]], a spirit formed from violent thoughts that attacks people psychically to destroy their mind to it can posses their body.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.

* [[Apparition]]

Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.

* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]

* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books.

* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fiend Folio

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.

* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.
* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books.

* [[Yuan-ti]] Anathema, see page. Also include rules for items used by Anathemas. Blasphemous weapons have evil spirits bound into them and deal damage like an unholy weapon and inflict a ''blasphemy'' effect and also weaken good characters who try to wield them. A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices. Sickening weapons are unholy weapons that can also weaken good characters on a critical hit. Venomous fire is similar to alchemist's fire that also can do poison damage to what it burns.
* [[Yugoloth]]
** Piscoloth
** Skeroloth
* [[Yurian]], a crab like creature that walks around on two legs like a humanoid.
* [[Zodar]], a strange construct that looks like a suit of metal armor but is actually made of ceramic and muscle tissue. They almost never speak, but when they do everyone can understand them, and they also have an ability that works like the ''wish'' spell they can, but usually don't, use once per year. Nobody knows where they came from, but they sometimes join parties of adventurers.

===[[Prestige Class]]es:===
* [[Fiend of Blasphemy]], an evil outsider that leads a cult of minions who are magically bound to it and gains spells like an evil cleric.
* [[Fiend of Corruption]], an evil outsider who specializes in turning good mortals evil through temptation. They have abilities that let them give rewards to mortals who do evil, such as the fiendish grafts later in this book.
* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

There is no saving throw for this curse, the ''remove curse'' spell is only partially effective and only has any effect if applied immediately, and the hound is impossible to harm in any way. This probably was put into the book to give DMs a way to more easily kill off misbehaving player characters without having to resort to falling rocks or sending monsters that risk a TPK.

* [[Thoqqua]], a burning hot worm monster that tunnels through rock, like a smaller, fiery version of the [[Purple Worm]].

* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.

When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.

* [[Vortex]], a small sphere that generates a miniature tornado around itself.

They ambush their victim from the ethereal plane and attempt to either subdue or paralyze them with their venomous claws and grapple them and carry them back to the ethereal plane. They can be warded off with a ''protection from evil'' spell and it is extremely vulnerable while it is switching from the material plane to the ethereal and grappling a victim.
* [[Xvart]]
* [[Yellow musk creeper]], a plant that sprays victims with mind controlling dust from its flowers which lures them into the plant so it can drain their intelligence. If the victim dies from the intelligence drain, a new flower is added to the plant, but if the victim survives they become a yellow musk zombie.
* [[Yellow musk zombie]], a humanoid that has a yellow musk creeper seed implanted in their brain which allows the plant to control them. They can be restored back to normal using magic, but only if the plant that turned them is killed first. If not cured they will eventually die and grow into a new creeper.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.
* [[Darter]], a blood drinking lizard that can fire it fangs as darts that cause paralysis.
* [[Denzelian]]
* [[Gem dragon]]
** Amethyst dragon
** Crystal dragon
** Emerald dragon
** Sapphire dragon
** Topaz dragon
* [[Dune stalker]], now has a more reptilian appearance.
* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.

* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.

* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking. Especially considering how later 3.x edition Monster Manuals declined in quality, this book probably could've been released as just another Monster Manual.

* [[Swarm]], any large swarm of monsters treated as one monster.

* [[Yuan-ti]] Anathema, see page. Also include rules for items used by Anathemas. Blasphemous weapons have evil spirits bound into them and deal damage like an unholy weapon and inflict a ''blasphemy'' effect and also weaken good characters who try to wield them. A serpent symbol is a holy symbol that can cast ''disintegrate'' and ''destruction'', but can only be wielded by a Yuan-ti or someone who can use magic devices.

* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fiend Folio

2020-07-15T03:17:02Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* 3rd Editon */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

=List of Monsters=
(Under construction)
==1st Edition==
* [[Aarakocra]]
* [[Achaierai]] a giant evil bird with a spherical body with no neck and tiny wings and four long metallic legs it attacks with. They can release poison smoke when badly injured. This should give you a good idea of the kinds of monsters that are to follow.
* [[Adherer]], a weird creature that looks like a mummy but sweats glue.
* [[Alaex]], a personification of a god's anger that resembles a duplicate of the person it has been sent to punish.
* [[Algoid]], a humanoid that actually is a colony of intelligent algae. They can use mind blast and can control trees like a [[treant]]. They are immune to psionic attacks, edged weapons of less than +2 quality, fire, and electricity, but take damage from some spells that affect water.
* [[Al-mi'raj]], a killer rabbit with a unicorn's horn.
* [[Apparition]], an undead that cannot cause physical harm, so it tries to scare people to death.
* [[Assassin bug]], giant flies that attack humans in male/female pairs. The male paralyzes the victim so that the female can lay their eggs in their wounds.
* [[Astral searcher]], a spirit formed from violent thoughts that attacks people psychically to destroy their mind to it can posses their body.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]

Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.

** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]

* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
===Monsters===
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books.

* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

''"Hi, I'm Maug! Half-robot, half-also-robot. I'm my own best friend."

Everyone knows about the [[warforged]] from 3.5e [[Dungeons and Dragons]], and how their main draw is that they let you play as a [[awesome|goddamn robot]] in a steampunk fantasy setting. The catch is, they're only half-robot, unless you take the Juggernaut prestige class. Would you be surprised to learn that Third Edition not only offered a way to play as something that was 100% robot, but did so ''before'' the Warforged?

We're talking about the ''Maug'', who appeared in the 3.0e [[Fiend Folio]], featuring darkvision, +7 natural armor, immunity to mind-affecting shenanigans, automatic self-repair capability, '''+10 strength''', a double-ended sword like Darth Motherfucking Maul, and a bunch of other shit that Warforged players wished they had. Also, just like warforged, their favored class was Fighter because they were created by some other race to fight in that race's wars. Unfortunately, they ended up getting overlooked because they didn't get [[Eberron|literally an entire campaign setting that existed for no other purpose than to promote them]].

They're technically an NPC race, but with a level adjustment, meaning that using them as a playable race will require a teeny bit of math and houseruling. However, they speak Common, walk on land, and have arms for holding weapons, so they're still infinitely more playable than the goddamn [[ixitxachitl]].

The Fiend Folio also includes rules for grafts that can be applied to maugs, though only a maug spellcaster can create them.

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* Grafts and Symbionts */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.

Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.

* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]

* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.

Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]

* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books.

** Plague ant swarm, ants that spread disease and cause serious bleeding with their attacks.
** Lesser pack [[Cranium Rat]] swarm.
** Average pack [[Cranium Rat]] swarm.
** Greater pack [[Cranium Rat]] swarm.
** Bloodfiend locust swarm, energy draining locusts that reanimate their victims as vampire spawn.
** Rapture locust swarm, flesh eating locusts affect people that see them as the ''hypnotic pattern'' spell and people who they feast on may become enraptured and stand still while they are eaten.
** Scarab beetle swarm, flesh eating scarab beetles that can quickly reduce living things to nothing.
** Viper swarm, a swarm of venomous snakes that shares a single mind.
** Wasp swarm, you know what they are, swarm of [[That Guy|tiny little jerks]].

* [[Terlen]], a shark with extra long fins that allow it to fly. We are doomed.
* [[Terror bird]], a large flightless carnivorous bird. This is an actually real but extinct animal.
* [[Thunder worm]], a colossal sized incorporeal giant worm that looks like a thunder cloud.
* [[Ti-khana]] Template, a reptilian creature that is part [[Yuan-ti]], giving it a venomous bite and several psionic abilities, including turning into a viper. The example is a ti-khana deinonychus.
* [[Tunnel Terror]], a huge stony psionic worm with a hollow body that pretends to be the walls of a tunnel to trick prey into walking inside it. This book has a lot of giant worm monsters, doesn't it?
* [[Ulgurstasta]], a gargantuan inteligent undead maggot with many eyes created by [[Kyuss]]. Please no more worms! We have enough. Their stomach acid converts people they swallow or vomit on into skeletons, and their bodies are covered in 40-foot long tendrils that block nonmagical ranged weapon attacks and inflict slashing damage to everything around them.
* [[Varrangoin]], skull-faced poison-tailed bat people from the [[Abyss]]
** Acanist varrangoin, the leaders who have the abilities of wizards and are immune to low level spells

They almost never speak, but when they do everyone can understand them, and they also have an ability that works like the ''wish'' spell they can, but usually don't, use once per year. Nobody knows where they came from, but they sometimes join parties of adventurers.

===[[Prestige Class]]es:===
* [[Fiend of Blasphemy]], an evil outsider that leads a cult of minions who are magically bound to it and gains spells like an evil cleric.
* [[Fiend of Corruption]], an evil outsider who specializes in turning good mortals evil through temptation. They have abilities that let them give rewards to mortals who do evil, such as the fiendish grafts later in this book.
* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

===Grafts and Symbionts===
Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats since they can act as independent beings, but also have an ego score like a sentient magic item which may allow them to take control of their host, while grafts don't have monster stats can be created like magic items and function similarly to non-sentient magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboleth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

====Symbionts====
* Cerebral symbionts, symbionts with psionic abilties that may have been created by or have some connection to [[Illithid]]s
** Cerebral hood, a creatures resembling a small [[Cloaker]] with a long spiky tail that engulfs a host's head and sticks its tail down their throat, but allows the host to see by sharing its senses. It feeds on the host's mental energy and allows them to survive without eating or breathing. It has telepathy and it can use a powerful mind blast, but doing so causes intelligence damage to its host which they won't naturally recover from because it is constantly feeding on their intelligence at the same speed it heals.
** Mind leach, a fine sized parasite that burrows into a host and coils around the brainstem. They have several psionic abilities, but the stronger ones cause intelligence damage to their host, though they will eventually recover because it doesn't drain intelligence constantly.
** Psionic sinew, a worm like length of muscle tissue that can be attached to a creature's arm. It enhances the host's strength, protects itself and its host with a psychokinetic field, and can use the ''claws of the bear'' psionic power. Unlike the other symbionts it cannot forcefully bond with a host. They cannot communicate with their host but are able to understand spoken commands in Undercommon.
* Fiendish symbionts, like with fiendish grafts, they cause wisdom damage to good characters and can make non-evil character succumb to the temptation to do evil. All of them can communicate telepathically.
** Fiendish familiar, a small evil looking face that acts more like an intelligent graft. They are helpless without a host and have no abilities other than acting as a source of magical knowledge and enhancing the spellcasting abilities of their host.
** Gutworm, a worm that you can get infected with by drinking polluted water in the [[abyss]] and lives in your digestive tract. They improve the host's constitution, can protect them from poison, and give the host rage like a barbarian, but also give penalties to several checks and requires the host to eat extra food and lowers their endurance. They can be killed with a ''remove disease'' spell, but doing so will cause it to damage the host as it dies. They have no melee attacks.
** Soul tick, a blood drinking tick from [[Baator]]. It empowers death, evil, and negative energy spells cast by the host while impeding good, chaos, and positive energy spells and also can protect the host from chaos and good. It also drains the host's constitution by feeding and can feed faster than the host naturally heals if they choose too.
* Ghostly visage, a incorporeal spirit that can manifest as a face on its host's body, including over their own face, which can paralyze people that look at it with fear. It also protects the host form mind affecting effects.

Fleshcrafting

2020-07-15T01:35:20Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* D&D */

'''Fleshcrafting''', also known as '''Fleshwarping''', is a term used on /tg/ as a catch-all to a specific form of dark magic and/or mad science that revolves around augmenting, transforming, shaping, sculpting and creating life, typically through a horrific amalgamation of alchemy, surgery and, if present, sorcery. Common uses of fleshcrafting include producing grotesque grafted biological augments or weapons, and creating monsters from corpse-pieces or living beings, usually to serve as servants of some description. This field of interest is usually restricted to races and individuals of the evil NPC variety, as it is generally seen as being too morally reprehensible (or overpowered) to allow PCs to have it.

==D&D==
Fleshcrafting has been used in the background of various monsters and even races since [[Dungeons & Dragons]] was first a thing. The [[Flesh Golem]], the [[Broken One]], the [[Bulette]], the [[Owlbear]] and many more are usually said to be the result of mad [[wizard]]s or dark [[artificer]]s playing around with the secret of life. Heck, even [[Mongrelfolk]] have been portrayed as fleshcrafted once or twice; the [[Darklord]] of G'henna has the ability to transform worshippers of [[Zhakata]] he doesn't like into mongrelfolk.

In [[Advanced Dungeons & Dragons]] 2nd edition, PCs were pretty much restricted from using this style, although the Anatomist [[kits]] for the [[Necromancer]] ([[Wizard]]) did eventually allow the player to build flesh golems and, technically, the [[Xixchil]] could touch upon it through its racial ability to self-improve by grafting on armor and weapon-limbs. Several unique NPC monsters also existed to represent victims of flesh-crafting experiments.

In 3rd edition, PCs could actually get involved in this themselves. The principles of creating grafts were first introduced in the 3e [[Fiend Folio]], then expanded upon in [[Lords of Madness]], which presented the Graft Flesh item creation feat, several new [[aberration]] grafts, and the Fleshwarper, a [[Prestige Class]] specialized in augmenting itself and others by grafting on bits of defeated monsters. The [[Half-Golem]] template technically represents one branch of fleshcrafting study. A Major Artifact in the [[Book of Vile Darkness]] [[splatbook]] called "The Despoiler of Flesh" is a rod made from human tongues sewn together, which grants its wielder the ability to mutate others more or less as they see fit. [[Fleshcrafter]] was also a class presented in [[Dragon Magazine]].

It appears extensively in the Eberron setting, being the specialty of the Daelkyr and their minions, and the source of all aberrations in the setting. Even one of the races called out as masters of grafting and flesh crafting in d&d, mindflayers, are a product of flesh crafting. They run the gamut of the standard grafts seen in the fiend folio, cool fleshy armor, a ball of meat that mutates anything you put in it, and whole new races made of the various goblinoids. A few other factions get in on the fun, but fleshworking is the Daelkyr's specialty and they're better at it than anyone else.

In [[Pathfinder]], several archetypes for the [[Alchemist]] make use of Fleshcrafting, whilst it is an "artform" mastered and wielded by both the [[drow]] and the [[derro]]. The drow in particular have created a number of unique, horrific monster species through their established procedures for warping living organisms to their liking.

The [[Ravenloft]] fan-wiki divides Fleshcrafting into two branches; Biomancy (magical & psionic fleshcrafting) and Bio-Engineering (mad science fleshcrafting).

==WH40K==
In [[Warhammer 40,000]], there are several examples of this form of artifice.

The absolute champions of it of the [[Haemonculi]] of the [[Dark Eldar]], and several other Dark Eldar units actually represent the fruits of their labor at sculpting flesh into new servile forms.

The Magos Biologis of the [[Adeptus Mechanicus]] also experiment in this field, as their teachings lead them to prefer bio-grafts and organic augmentations over the traditional cybernetics of their fellows.

Although it is often referred to as "genetical enhancement", the processus of using [[Gene-seed]] to create a [[Space Marine]] is effectively a form of fleshcrafting. Indeed, it uses various external genetically cultured biological augments to transform a lowly human into a powerful Adeptus Astartes, and [[God-Emperor of Mankind|Big.E]] made sure they would not be genetically transmissible as He didn't want to turn all of mankind into Astartes. Despite this, most works refer to it as "genhancement" to convey it is an ([[skub|arguably]]) safe and controlled process instead of the product of mad science or some dark magic.

The forces of [[Chaos]] mutate the flesh and bone of their mortal followers as their see fit, whether intentionally by invoking directly into their power, or accidentally by being exposed to warp energies. The usefulness of these differ (as these can range anywhere from sprouting wings to allow flight, having a lash-whip tentacle for an arm that overloads the senses of your opponent, improved physical musculature that would give even Chapter Masters a run for their money, to just an unrecognizable lump of flesh somewhere on your body with no real benefit), but it takes a lot of physical and mental power to handle the mutations that the Dark gods bestow upon their followers, and also a lot of luck, as being too physically and/or mentally frail, or simply being at the bad end of their patron god's mood when they gain their attention, can result in them [[Chaos Spawn|devolving into what we can only describe as the Dark God's failed arts-and-craft project]].

The [[Tyranids]]' entire species is based on fleshcrafting, constantly absorbing new genetic material and analyzing it to provide new ways to modify and augment themselves on a physical and species level.

And, last but not least, let's not forget about [[Fabius Bile|Mr. Fabulous]] who's been <s>desecrating</s> CAREFULLY PERFORMING SCIENTIFIC EXPERIMENTS UPON anyone or anything that had the <s>misfortune</s> PRIVILEGE to get in the same room as him for the last ten millenia in order to create 'the perfect human being'.

==Other Games==
In [[Deadlands]], "Patchwork Science", a primitive form of fleshcrafting that amounts to making [[Flesh Golem]]s is mentioned in the second of its monster manuals, although Marshals are told emphatically that this is NOT to be allowed into player hands as an [[Arcane Background]].

The [[Tzimisce]] from [[Vampire: The Masquerade]] have the [[Vicissitude]] discipline, which grants them the power to shape flesh and bone at low levels, do all sorts of weird stuff, and become a monster, a puddle of sapient Vitae, a fucking dragon, and, in case of one Metuselah, a virus (it's not clear, whether he became ebola or AIDS).

[[Skaven]] [[Clan Moulder]] in [[Warhammer Fantasy]] specializes in this, mostly to create bigger and better breeds of rats.

The [[Phyrexia]]ns from [[Magic: The Gathering]] are not a wasteful bunch. If you don't need a body part, and it can be used somewhere else, they will take it, and use it. They also have nanobots called glistening oil that turns creatures into phyrexians. MTG also has thrulls which are living creatures made out of corpses.

Fleshcrafter is a character class in [[FAPP]] that specializes in adding and removing assets and mutations to their self or others.

The Zerg from [[Starcraft]] are similar to the Tyranids, in culling essence from creatures to assimilate them, or alter one of their existing creatures with attributes from essence they have collected. No wonder Starcraft is accused of being a ripoff.

Fiend Folio

2020-07-15T01:33:47Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* 3rd Editon */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

* [[Sheet phantom]], a [[wraith]] resembling a bed sheet with a face that attacks by dropping on people and suffocating them. If they succeed, the sheet phantom merges with the corpse and becomes a sheet ghoul. Seriously, how old was the person who designed who designed the sheet phantom and sheet ghoul? 5 maybe?

* [[Tabaxi]]
* [[Tentamort]] a spherical creature with short suckered tentacles on one side of its body it uses to move around and two much longer tentacles on the other side it uses to attack.

* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.

When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.
* [[Vodyanoi]], a relative of the [[Umber Hulk]] that looks like a fish man instead of a bug. They lack the confusing gaze of an umber hulk, but can summon electric eels.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.

** Emerald dragon
** Sapphire dragon

* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]
* [[Hellcat]]

* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.
* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking.

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

They can only be damaged by silver and magic weapons, and can only be damaged by holy water while it is trying to merge with a human.

** Green slaad

* [[Tabaxi]]
* [[Tentamort]] a spherical creature with short suckered tentacles on one side of its body it uses to move around and two much longer tentacles on the other side it uses to attack.

* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.
* [[Tirapheg]], an extremely weird monster with three heads, three eyes that are all on the same head with the third on the back of the head, three arms with the third growing from the chest, three fingers that are all on the middle arm, with the other two arms ending in blades, three legs, three toes all on the same legs, its mouth located on its chest under the middle arm, and three small tentacles between the middle arm and the mouth.

** Giant two-headed troll
** Ice troll
** Spirit troll

When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.
* [[Vodyanoi]], a relative of the [[Umber Hulk]] that looks like a fish man instead of a bug. They lack the confusing gaze of an umber hulk, but can summon electric eels.

* [[Vortex]], a small sphere that generates a miniature tornado around itself.
* [[Whipweed]], a plant like tentacle monster with two long tentacles it attacks with and eight small legs it uses to move around. Does this sound familiar?

* [[Xvart]]
* [[Yellow musk creeper]], a plant that sprays victims with mind controlling dust from its flowers which lures them into the plant so it can drain their intelligence. If the victim dies from the intelligence drain, a new flower is added to the plant, but if the victim survives they become a yellow musk zombie.
* [[Yellow musk zombie]], a humanoid that has a yellow musk creeper seed implanted in their brain which allows the plant to control them. They can be restored back to normal using magic, but only if the plant that turned them is killed first. If not cured they will eventually die and grow into a new creeper.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.
* [[Darter]], a blood drinking lizard that can fire it fangs as darts that cause paralysis.
* [[Denzelian]]
* [[Gem dragon]]
** Amethyst dragon
** Crystal dragon
** Emerald dragon
** Sapphire dragon
** Topaz dragon
* [[Dune stalker]], now has a more reptilian appearance.
* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]
* [[Hellcat]]
* [[Ice lizard]]
* [[Iron cobra]]
* [[Khargra]]
* [[Mantari]], its stinger tail works differently now. It now has a venom that causes temporary strength and dexterity loss.
* Great Mantari, a larger variant.
* [[Mephit]]
** Fire mephit
** Ice mephit
** Lava mephit
** Mist mephit
** Smoke mephit
** Steam mephit
* [[Penanggalan]]
* [[Pernicon]]
* [[Phantom stalker]]
* [[Quaggoth]]
* [[Retriever]]
* [[Ruve]], an intelligent dog with psionic powers. Although they are lawful good, they are extremely arrogant and obnoxious.
* [[Scathe]], an ugly white reptilian humanoids\ related to the [[harrier]], that lives in icy regions. They have poisonous beaks and are immune to cold.
* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.
* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking. Especially considering how later 3.x edition Monster Manuals declined in quality, this book probably could've been released as just another Monster Manual.
* [[Abrian]], an intelligent bird from the [[Abyss]] that looks like an ostrich with small arms instead of wings.
* Abyssal [[ghoul]], an ghoul from the abyss.
* [[Ahuizotl]], a monster from Aztec mythology. It is part dog, part monkey and has a hand on the end of its tail. It lives in water and attacks people to eat their eyes, teeth, and fingernails.
* [[Aoa]], a floating blob of silver liquid. Possibly is the neutral counterpart of the zag-ya and zeg-yi. They reflect energy instead of producing it and are attracted to magic. They are very dangerous to spellcasters and magic items as their touch dispels magic.
** Droplet
** Sphere
* [[Slime|Aquatic ooze]]
** Bloodbloater
** Flotsam ooze
** Reekmurk
* [[Bacchae]], humanoid outsiders that spend all of their time constantly drinking and partying. People who get drawn into the party risk becoming a Bacchae as well.
* [[Bhut]], a hideous incorporeal undead with a poison bite and is able to possess corpses. Except when possessing a body, they have a weakness against anything made of earth or stone.
* [[Blackstone gigant]], a stone construct that looks like a gargantuan woman with eight arms or a [[Marilith]]. Their touch can turn people to stone, and they can temporarily animate their victims into living statues.

Fiend Folio

2020-07-15T01:29:30Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* 3rd Editon */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]

Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.

* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]

* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]

* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books.

Their stomach acid converts people they swallow or vomit on into skeletons, and their bodies are covered in 40-foot long tendrils that block nonmagical ranged weapon attacks and inflict slashing damage to everything around them.
* [[Varrangoin]], skull-faced poison-tailed bat people from the [[Abyss]]
** Acanist varrangoin, the leaders who have the abilities of wizards and are immune to low level spells
** Lesser varrangoin, fighters who bullied by the other types and can have one of four different breathe weapons and explodes when it dies.
** Rager varrangoin, barbarians with a ''dispel magic'' ability and immunity to mind affecting magic and effects.
* [[Vine Horror]], appears to be the equivalent of the algoid from the previous two books. Loses the mind blast ability it had before and can only animate vines.
* [[Vorr]], rat dogs from the [[Abyss]]. Can turn into a living shadow and teleport between shadows.
* [[Wendigo]] Template. The example is a 4th level human sorcerer.
* [[Wicker man]], a huge wooden construct used for capturing human sacrifices which are then burned alive inside of it. They are immune to magic except for a few spells that affect wood. Probably inspired by the movie, The Wicker Wan.
* [[Yellow Musk Creeper]]
* [[Yellow Musk Zombie]] template, the example is an orc.
* [[Yuan-ti]] Anathema
* [[Yugoloth]]
** Piscoloth
** Skeroloth
* [[Yurian]], a crab like creature that walks around on two legs like a humanoid.
* [[Zodar]], a strange construct that looks like a suit of metal armor but is actually made of ceramic and muscle tissue. They almost never speak, but when they do everyone can understand them, and they also have an ability that works like the ''wish'' spell they can, but usually don't, use once per year. Nobody knows where they came from, but they sometimes join parties of adventurers.

===[[Prestige Class]]es:===
* [[Fiend of Blasphemy]], an evil outsider that leads a cult of minions who are magically bound to it and gains spells like an evil cleric.
* [[Fiend of Corruption]], an evil outsider who specializes in turning good mortals evil through temptation. They have abilities that let them give rewards to mortals who do evil, such as the fiendish grafts later in this book.
* [[Fiend of Possession]], an evil outsider who has learned to possess objects and people.

Grafts and Symbionts: Grafts and Symbionts are monstrous body parts that can be attached to creatures. Symbiotes are sentient creatures and have monster stats while grafts do not and can be created like magic items. Creating a graft requires the ''graft flesh'' feat for that type of graft. More grafts appear in other books. [[Lords of Madness]] includes a prestige class that specializes in making grafts and allows access to grafts that normally have race resctions on who can make them. And the book [[Tome and Blood]] includes some prestige classes that get some grafts automatically.

====Grafts====
* [[Aboloth]] grafts. Aboleths apply these grafts to their slaves. They can only be applied to [[Skum]] and creatures transformed by aboleth slime, and the graft will be destroyed if the transformed creature is healed. Includes ''aboleth tentacle'', ''mucus sheathe'', ''Skum eyes'', and ''skum tail''.
* [[Beholder]] grafts. Unlike most other grafts, the feat for making them is not race restricted. Beholder worshipers apply these grafts to themselves. Includes ''crown of eyes'', ''eye stalk'', ''gazing eye'', ''plated skin'', ''replacement eye'', and ''third eye''.
* Fiendish grafts. Given by fiends to mortals. They cause wisdom damage to good creatures and cause non-evil creatures to suffer temptations to do evil acts. Includes ''charming eye'', ''clawed arm'', ''fast leg'', ''fearsome eye'', ''feathered wings'', ''fiendish ear'', ''fiendish jaw'', ''fiendish skin'', ''flexible arm'', ''grappling tentacle'', ''long arm'', ''membranous wings'', ''springing leg'', ''stinging tail'', ''strong leg'', ''trampling leg'', and ''whip tail''.
* [[Illithid]] grafts. Given by illithids to their slaves. They have the drawback weakening resistance to mind effects. Includes ''antennae graft'', ''climbing legs'', ''goring horn'', ''grasping mandibles'', ''hauling back'', ''raking tentacles'', ''rending claw'', and ''weapon graft''.
* [[Maug]] grafts. Spellcasting maugs give them to other maugs. Includes ''locking hand'', ''rollers'', ''shoving arm'', ''shudder plate'', ''spike stones'', and ''stone splitter''.
* [[Undead]] grafts. Unlike most other grafts, the feat for making is not race restricted. Applied by necromancers to the living. Includes ''bonemail'', ''enervating arm'', ''paralyzing arm'', and ''weakening arm''.
* [[Yuan-ti]] grafts. Given by Yuan-ti to their humanoid minions. Includes ''added tail'', ''poison fangs'', ''replacement tail'', ''scaly skin'', and ''serpent arm''.

Fiend Folio

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* 3rd Editon */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

There is no saving throw for this curse, the ''remove curse'' spell is only partially effective and only has any effect if applied immediately, and the hound is impossible to harm in any way. This probably was put into the book to give DMs a way to more easily kill off misbehaving player characters without having to resort to falling rocks or sending monsters that risk a TPK.

If it succeeds the body it possesses will vanish with it. Victims that don't survive can't be resurrected without a powerful such as ''wish''. They can only be damaged by silver and magic weapons, and can only be damaged by holy water while it is trying to merge with a human.
* [[Mantari]], a flying ray with a stinger tail that does more damage the less constitution the victim has, and does quadruple damage if it hits the same target again the next round.

* [[Terithran]], a humanoid from the ethereal plane. Casting powerful magic other than cleric or druid magic on the material plane close to its layer on the ethereal plane makes it angry, and it will try to kidnap and punish the magic user responsible.
* [[Thoqqua]], a burning hot worm monster that tunnels through rock, like a smaller, fiery version of the [[Purple Worm]].
* [[Thork]], a bird resembling a stork, but its feathers are made out of copper, making it valuable. It defends itself by squirting boiling hot water.
* [[Throat leach]], a small leach that sucks that sucks blood from the person who accidentally swallows it while drinking from the water it lives in, choking them to death if it isn't removed.
* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.
* [[Tirapheg]], an extremely weird monster with three heads, three eyes that are all on the same head with the third on the back of the head, three arms with the third growing from the chest, three fingers that are all on the middle arm, with the other two arms ending in blades, three legs, three toes all on the same legs, its mouth located on its chest under the middle arm, and three small tentacles between the middle arm and the mouth.

* [[Trilloch]], an invisible energy creature that feeds on the dying.

* [[Troll]]
** Giant troll
** Giant two-headed troll
** Ice troll
** Spirit troll
* [[Tween]], an Ethereal creature that bonds to a host and appears as a shadowy copy of that host. It grants the host increased luck, but at the cost of giving bad luck to everyone around them. Possibly the monster with the stupidest name in the book.

When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.
* [[Vodyanoi]], a relative of the [[Umber Hulk]] that looks like a fish man instead of a bug. They lack the confusing gaze of an umber hulk, but can summon electric eels.

* [[Vortex]], a small sphere that generates a miniature tornado around itself.
* [[Whipweed]], a plant like tentacle monster with two long tentacles it attacks with and eight small legs it uses to move around. Does this sound familiar?
* [[Witherstench]], a hairless skunk like creature that produces a horrible smell constantly.
* [[Witherweed]], a plant with venom that drains dexterity and can cause seizures. It is weak against fire, but when it burns it produces smoke that can instantly kill people that inhale it.
* [[Xill]], a four armed monster reproduces by implanting eggs in humanoids xenomorph style. Seriously, we don't need anymore of these. They ambush their victim from the ethereal plane and attempt to either subdue or paralyze them with their venomous claws and grapple them and carry them back to the ethereal plane. They can be warded off with a ''protection from evil'' spell and it is extremely vulnerable while it is switching from the material plane to the ethereal and grappling a victim.
* [[Xvart]]
* [[Yellow musk creeper]], a plant that sprays victims with mind controlling dust from its flowers which lures them into the plant so it can drain their intelligence. If the victim dies from the intelligence drain, a new flower is added to the plant, but if the victim survives they become a yellow musk zombie.
* [[Yellow musk zombie]], a humanoid that has a yellow musk creeper seed implanted in their brain which allows the plant to control them. They can be restored back to normal using magic, but only if the plant that turned them is killed first. If not cured they will eventually die and grow into a new creeper.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.
* [[Darter]], a blood drinking lizard that can fire it fangs as darts that cause paralysis.
* [[Denzelian]]
* [[Gem dragon]]
** Amethyst dragon
** Crystal dragon
** Emerald dragon
** Sapphire dragon
** Topaz dragon
* [[Dune stalker]], now has a more reptilian appearance.
* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]
* [[Hellcat]]
* [[Ice lizard]]
* [[Iron cobra]]
* [[Khargra]]
* [[Mantari]], its stinger tail works differently now. It now has a venom that causes temporary strength and dexterity loss.
* Great Mantari, a larger variant.
* [[Mephit]]
** Fire mephit
** Ice mephit
** Lava mephit
** Mist mephit
** Smoke mephit
** Steam mephit
* [[Penanggalan]]
* [[Pernicon]]
* [[Phantom stalker]]
* [[Quaggoth]]
* [[Retriever]]
* [[Ruve]], an intelligent dog with psionic powers. Although they are lawful good, they are extremely arrogant and obnoxious.
* [[Scathe]], an ugly white reptilian humanoids\ related to the [[harrier]], that lives in icy regions. They have poisonous beaks and are immune to cold.
* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.

==3rd Editon==
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking. Especially considering how later 3.x edition Monster Manuals declined in quality, this book probably could've been released as just another Monster Manual.

Fiend Folio

2020-07-15T00:02:51Z

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* 3rd Editon */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]

Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.

* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]

* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.

Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.

* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]

* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books.

* [[Terlen]], a shark with extra long fins that allow it to fly. We are doomed.
* [[Terror bird]], a large flightless carnivorous bird. This is an actually real but extinct animal.
* [[Thunder worm]], a colossal sized incorporeal giant worm that looks like a thunder cloud.
* [[Ti-khana]] Template, a reptilian creature that is part [[Yuan-ti]], giving it a venomous bite and several psionic abilities, including turning into a viper. The example is a ti-khana deinonychus.
* [[Tunnel Terror]], a huge stony psionic worm with a hollow body that pretends to be the walls of a tunnel to trick prey into walking inside it. This book has a lot of giant worm monsters, doesn't it?
* [[Ulgurstasta]], a gargantuan inteligent undead maggot with many eyes created by [[Kyuss]]. Please no more worms! We have enough. Their stomach acid converts people they swallow or vomit on into skeletons, and their bodies are covered in 40-foot long tendrils that block nonmagical ranged weapon attacks and inflict slashing damage to everything around them.
* [[Varrangoin]], skull-faced poison-tailed bat people from the [[Abyss]]
** Acanist varrangoin, the leaders who have the abilities of wizards and are immune to low level spells

* [[Wendigo]] Template. The example is a 4th level human sorcerer.
* [[Wicker man]], a huge wooden construct used for capturing human sacrifices which are then burned alive inside of it. They are immune to magic except for a few spells that affect wood. Probably inspired by the movie, The Wicker Wan.

* [[Yellow Musk Zombie]] template, the example is an orc.
* [[Yuan-ti]] Anathema
* [[Yugoloth]]
** Piscoloth
** Skeroloth
* [[Yurian]], a crab like creature that walks around on two legs like a humanoid.
* [[Zodar]], a strange construct that looks like a suit of metal armor but is actually made of ceramic and muscle tissue. They almost never speak, but when they do everyone can understand them, and they also have an ability that works like the ''wish'' spell they can use once per year, but almost never use that either. Nobody knows where they came from, but they sometimes join parties of adventurers.

Fiend Folio

2601:203:480:4C60:A0AC:5C3C:53A6:E621: /* 3rd Editon */

{{WTF}}
The '''Fiend Folio''' was a 1981 [[Monster Manual]]-like book for [[Advanced Dungeons & Dragons]] 1st edition. It served to gather up the various monsters that had been submitted to TSR works but not made the MM itself as of its 1978 edition - for instance, [[kuo-toa]], [[svirfneblin]] and of course the official full writeup of [[drow]]. Most came out of [[White Dwarf]]'s [[Fiend Factory]] as of then. Many of the latter monsters are laughable crap, like the [[Xvart]] which sounds like Fart, so have fallen into obscurity or - like the [[Flumph]] - notoriety.

But a few gems do appear amongst the dross: usually cited here, Charles Stross' badass [[Githyanki]] and [[Githzerai]]. We could also shout-out to the Dark Ones, the Creepers and Stalkers. Who knows why later publishers didn't publish stuff featuring those guys, they were fucking sweet.

A 3rd-party company called Necromancer Games vaguely affiliated with [[White Wolf]] released a spiritual successor to the Fiend Folio in "The Tome of Horrors", which adapted many, if not all, of these monsters to [[Dungeons & Dragons 3rd Edition]]. WotC for 3e did its own Fiend Folio, figuring that was a decent brand for niche monsters - so Caryatid Columns and those Dark Ones were here. Others were brought back for [[Pathfinder]]. With the release of [[Dungeons & Dragons 5th Edition]], many of these monsters are starting to be revived and return to the spotlight. The [[Lava Children]], Flumph, and [[Berbalang]] all entered the canon here, among others. 5th edition also has a new series of PDF supplements called [[Mordenkainen's Fiendish Folio]] which updates even more obscure monsters from the original Fiend Folio to 5th edition.

There is no saving throw for this curse, the ''remove curse'' spell is only partially effective and only has any effect if applied immediately, and the hound is impossible to harm in any way. This probably was put into the book to give DMs a way to more easily kill off misbehaving player characters without having to resort to falling rocks or sending monsters that risk a TPK.

They can only be damaged by silver and magic weapons, and can only be damaged by holy water while it is trying to merge with a human.

* [[Terithran]], a humanoid from the ethereal plane. Casting powerful magic other than cleric or druid magic on the material plane close to its layer on the ethereal plane makes it angry, and it will try to kidnap and punish the magic user responsible.
* [[Thoqqua]], a burning hot worm monster that tunnels through rock, like a smaller, fiery version of the [[Purple Worm]].

* [[Tiger fly]], a giant wasp with a human face. Males have upper arms that end in sickle like blades and a poisonous sting, and females have a paralyzing sting. They are yet another monster that lays eggs in victims xenomorph style. The trope is definitely getting overused.

When a vision is destroyed, the illusionary aging becomes real if the victim fails their save. They can be damaged by ''bless'' and ''dispel illusion''.
* [[Vodyanoi]], a relative of the [[Umber Hulk]] that looks like a fish man instead of a bug. They lack the confusing gaze of an umber hulk, but can summon electric eels.

* [[Vortex]], a small sphere that generates a miniature tornado around itself.
* [[Whipweed]], a plant like tentacle monster with two long tentacles it attacks with and eight small legs it uses to move around. Does this sound familiar?

They ambush their victim from the ethereal plane and attempt to either subdue or paralyze them with their venomous claws and grapple them and carry them back to the ethereal plane. They can be warded off with a ''protection from evil'' spell and it is extremely vulnerable while it is switching from the material plane to the ethereal and grappling a victim.
* [[Xvart]]
* [[Yellow musk creeper]], a plant that sprays victims with mind controlling dust from its flowers which lures them into the plant so it can drain their intelligence. If the victim dies from the intelligence drain, a new flower is added to the plant, but if the victim survives they become a yellow musk zombie.
* [[Yellow musk zombie]], a humanoid that has a yellow musk creeper seed implanted in their brain which allows the plant to control them. They can be restored back to normal using magic, but only if the plant that turned them is killed first. If not cured they will eventually die and grow into a new creeper.

==2nd Edition==
2rd Edition's version of the Fiend Folio was the 14th volume of the [[Monstrous Compendium]] series. A lot of monsters from the previous Fiend Folio returned with expanded and revised fluff. The artwork in this book is also a lot better so a lot of (but certainly not all of) the dumb looking monsters are less so. For some reason, the artwork of several of the monsters are not consistent with their descriptions, such as the volt, which is described the same way as in the previous edition, but the picture looks completely different.
* [[Slime|Aballin]]
* [[Achaierai]], still stupid looking.
* [[Adherer]]
* [[Algoid]], definitely looks a lot cooler now.
* Purple algoid, a new variant that lives in arctic areas. Instead of controlling trees they can talk to crustaceans.
* [[Al-mi'raj]], now has the ability to teleport short distances.
* [[Apparition]]
* [[Caterwaul]]
* [[Crabfolk|Crabman]]
* [[Coffer corpse]], the artwork is a huge improvement.
* [[Dark creeper]]
* [[Dark stalker]], for some reason he appears to be dressed as a superhero.
* [[Darter]], a blood drinking lizard that can fire it fangs as darts that cause paralysis.
* [[Denzelian]]
* [[Gem dragon]]
** Amethyst dragon
** Crystal dragon
** Emerald dragon
** Sapphire dragon
** Topaz dragon
* [[Dune stalker]], now has a more reptilian appearance.
* [[Fire falcon]], a bird that can fire explosive spheres from its wings.
* [[Faux fairy]], a fairy creature that lives to cause confusion through lies and tricks. They can copy the appearance of any kind of [[fairy]] creature. They completely immune to all spells. Whenever they are hit by a spell, they absorb the spell and store it. When they no longer have room to store spells, casting a spell at them will cause them to release one of the previously stored spells at the caster to make room. At night they merge with a piece of dead wood. Burning the piece of wood will cause the spells they have stored to release, and cutting it up will cause only some of the stored spells to release and make the faux fairy split in into two faux fairies.
* [[Firedrake]]
* [[Flawder]], intelligent neutral good sea snails.
* [[Fyrefly]], a insect that reproduces in fires. A adult fyrefly normally is harmless but when it is ready to reproduce, it will fly into a fire and rapidly divide into a swarm of up to 64 extremely aggressing flaming insects. Luckily the swarm only lasts for ten rounds of combat before the flies go dormant and change into adults.
* [[Gambado]]
* [[Garbug]], the two different types are now the male and female of the same species. Oddly, it is the blood drinking black garbug that is that male, while in real life, blood drinking insects like mosquitos usually are females. Females, but not males, can be trained as guard animals.
** Black garbug
** Violet garbug
* [[Fog giant]]
* [[Gibberling]], now with a more canine appearance.
* [[Beholder|Gorbel]]
* [[Grimlock]]
* [[Hellcat]]
* [[Ice lizard]]
* [[Iron cobra]]
* [[Khargra]]
* [[Mantari]], its stinger tail works differently now. It now has a venom that causes temporary strength and dexterity loss.
* Great Mantari, a larger variant.
* [[Mephit]]
** Fire mephit
** Ice mephit
** Lava mephit
** Mist mephit
** Smoke mephit
** Steam mephit
* [[Penanggalan]]
* [[Pernicon]]
* [[Phantom stalker]]
* [[Quaggoth]]
* [[Retriever]]
* [[Ruve]], an intelligent dog with psionic powers. Although they are lawful good, they are extremely arrogant and obnoxious.
* [[Scathe]], an ugly white reptilian humanoids\ related to the [[harrier]], that lives in icy regions. They have poisonous beaks and are immune to cold.
* Scathe larva, identical to harrier larva.
* [[Sheet ghoul]], it now sprays acid from the mouth instead of the nose. Probably an attempt to make it less silly.
* [[Sheet phantom]], no longer has a face. Probably an improvement.
* [[Shocker]], completely redesigned. It now looks like a suit of armor crackling with electricity and it no longer crumbles into dust after its first attack. Now confirmed to be an elemental from the Plane of Lightning.
* [[Spanner]], [[Gotcha Monster|an intelligent living stone bridge]] that can talk and likes to gossip. It will drop you if you make it mad or try to cross it without permission. This should be fun for the DM to roleplay.
* [[Stwinger]], a tiny humanoid with short wings whose favorite activity is swinging around using peoples hair or beards until they fall unconscious from the pain of their hair or beards being pulled on. They produce a pheremone that charms victims into letting them do this and even if they fail the stwinger is difficult to attack because of how cute it is.
* [[Sussurus]], now redesigned into a plant monster related to the [[shambling mound]] made of bamboo. The song they produce now affects both the living and the undead.
* [[Slime|Symbiotic jelly]]
* [[Terithran]], now it attacks spellcasters because it likes to eat them, rather than wanting to punish them for disturbing the ethereal plane.
* [[Thunder children]], black humanoids that come out during thunderstorms to feed on people's fear. Their bites inflict electric damage and they can cast several spells, sense fear, and turn into a gaseous form. They like to scare people do death by sneakily doing things to increase the victims fear of the storm. The plane of [[Ravenloft]] is a paradise for them.
* Ice [[Troll]]
* [[Tween]], it now looks like a short ugly humanoid while on the ethereal plane and it can fight with weapons but only against other things on the ethereal plane.
* [[Umpleby]]
* [[Urdunnir]], a relative of the [[dwarf]] that has the ability to pass through stone and can innately cast ''stone shape'' and ''shape metal''. They can kill people by dragging them into stone using their special ability and then leaving them behind.
* [[Volt]]
* [[Xill]]
* [[Xvart]]
* [[Zygraat]], yet another bird monster with extra legs. This one is actually part spider. It can make webs and has a venomous bite.

==3rd Editon==
Fewer monsters from the two previous folios return. It has way fewer stupid monsters. A lot of the monsters here probably deserved to go in the monster manuals or other books instead and many of the monsters from the previous folios that didn't appear in this book did appear in other books. The Achaierai actually made it into the first [[Monster Manual]] and the artist managed to make it less dumb looking. Especially considering how later 3.x edition Monster Manuals declined in quality, this book probably could've been released as just another Monster Manual.
