Editing Fiend Folio (section)

===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.
