Editing Psionics

{{stub}}

'''Psionics''' is similar to [[Magic]], in that it is the ability to do shit that the laws of physics say you shouldn't, but is considered more inherently "science fictiony" than magic, which is seen as the realm of fantasy.

The general definition of psionics is that it is a power that stems from the user's mind, and as such it tends to focus more on mental effects; telepathy, mind control, hallucinations/illusions and so forth. However, in "softer" settings, taking inspiration from the real-world belief in telekinesis (the ability to move physical objects by willpower alone), psionics can get much more flashy, until the border between it and regular magic boils down more to semantics than anything else.

==Dungeons & Dragons==
Psionics has a long tradition in [[Dungeons & Dragons]], and two of its most iconic [[aberration]]s, the [[Aboleth]] and the [[Illithid]], are defined by their connection to it. However, it's long been the black sheep, to the point that [[Gary Gygax]] himself thought that it was a bad idea to include it. 

Seriously, long-running consensus on /tg/ is that Dungeons & Dragons' psionics is cursed. That these books are not RPG supplements, but grimoires of a sadistic cult, playing with your emotions. To have any D&D psionics book present in the room will ensure you always roll poorly. Another common opinion that psions in D&D are overpowered. This stems from time and time again of game designers trying to make psychic powers something different than spellcasting, and fucking up the game design doing it.

The main issues are two-fold: one, it's hard to distinguish psionics from the arcane and divine magics running around already. Two, the rule-set tends to be an extra layer of ridiculously complicated even by D&D standards. 3rd edition was notable for presenting only two ways of handling it; either making it functionally indistinguishable from magic, or something totally seperate and thus requiring a huge amount of extra work on top of what is already considered one of the harder editions to GM for.

Ironically, 4th edition D&D actually had the easiest, simplest, most well-integrated psionics system seen in D&D to date. In 4e, psions are still mechanically different, but not to game-tangling extents: psionic classes don't get Encounter powers. Instead, they get a much larger array of at-will powers and a level-determined amount of "power points". Psionic at-wills feature a mechanic called "Augmentation", where a PC can spend some of its power points to buff up the effect. Psionic powers also place much heavier emphasis on the Psychic and Force damage types, making them much harder to resist for most critters.

Traditionally, D&D psionics was divided into six psionic schools, in a repeat of the magic system:
* '''Clairsentience''' covered psionic powers that related to expanded sensory perception.
* '''Psychokinesis''' covered psionic powers that physically affected the world.
* '''Psychometabolism''' covered psionic powers that modified and mutated the body in various ways.
* '''Psychoportation''' covered psionic powers relating to manipulating space.
* '''Telepathy''' covered psionic powers relating to direct mental communication.
* '''Metapsionics''' covered... well, basically a grab-bag of various powers that didn't mesh into any of the others.

Dungeons & Dragons initially introduced psionics as just "inherent powers", special abilities you could get if you had really, really lucky rolls. AD&D 2nd edition introduced the first ever psionic class, the ''Psionicist'', which was all about growing in psionic powers. 3rd edition renamed the Psionicist to just the [[Psion]] and introduced further psionic classes, many of whom were just specific flavors of psionicist or "psychic versions" of existing classes, like the [[Soulknife]], [[Erudite]], [[Wilder]] and [[Psychic Warrior]]. 4th edition divided psionics up between three classes - the [[Psion]], [[Ardent]] and [[Battlemind]] - although the [[Monk]] was also considered to use the "Psychic Power Source".

==Pathfinder==
[[Pathfinder]], of course, has its own psionic system, which it tries to differentiate by using real-world beliefs in psionics and occultism. It was introduced to the world in the Occult Adventures sourcebook, which was followed by the far-shorter Occult Bestiary, for more psionic-focused enemies.

==Warhammer 40k==
[[Warhammer 40,000]] is ''the'' premier /tg/ example of the "psionics is just space magic!" design.

==Star Wars==
The Force in [[Star Wars]] is just a fancy name for psionics. Ironically, although treated like magic, it functions more like classic psionics; Force Users predominantly produce mental effects (the famous "Jedi Mind Trick" is basically a psychic Charm Person spell) and telekinesis, although there are more exotic powers as well - most of these tend to be Dark Side, though.

==Star Trek==
Ironically, despite the vast amount of weird space shit that pops up in [[Star Trek]], psionics isn't very common. Vulcans have the ability to telepathically probe and manipulate minds through a meditative trance that requires physical contact, the infamous "Vulcan Mind Meld", whilst Betazoids are characterized as an empathic (emotion-sensing) species.
