Original Dungeons & Dragons Psionics were first introduced in the supplement
Eldritch Wizardry (1976).
Advanced Dungeons & Dragons First Edition Optional rules for psionics were included in the original ''
Player's Handbook, which presented them as an optional ability available to many monsters and to players who could qualify with lucky rolls. There was no specific character class that specialized in psionics, although an unofficial one, the Psionicist, was introduced in Dragon Magazine issue #78. Much of the rules mechanics for psionic combat were found separately in the Dungeon Masters Guide''.
Second Edition Psionics rules first appeared
The Complete Psionics Handbook. Game designer
Rick Swan described the book as "a straightforward presentation of an easily managed and highly playable system that clears up the ambiguities in the 1st Edition game and adds a number of elegant new touches". Several
Dark Sun products introduced new psionic powers.
Revision The psionics system was greatly revised in ''
Player's Option: Skills & Powers and the revised Dark Sun Campaign Setting''. The psionic abilities possessed by a character are determined by the Wisdom, Constitution, and Intelligence scores of that character. The psionicist was renamed "psion" and more closely resembled the
Sorcerer class in terms of combat ability. A new character class, the
psychic warrior, was introduced. Psions were given several new abilities and psionic powers that were intended to complement the new and revised abilities of the magic-using character classes, and psionic items were introduced to give psionic characters an alternative to using magical items. The psionics system was again revised for the
3.5 edition of the game, in the
Expanded Psionics Handbook (2004). The May 2004 issue of
Dragon introduced the "Athasian elan" as a playable character race for the
Dark Sun campaign setting. In the
Eberron Campaign Setting (2004), many psionic characters have some connection to the quori - malevolent spirits from the dreamrealm of Dal Quor - with such talents being particularly common on the quori-ruled continent of Sarlona. The book also introduces "Kalashtar" as a playable race, psionically-gifted humans whose ancestors offered sanctuary to rogue quori within their own souls. Psionics- and quori-related mechanics were expanded upon in later
Eberron supplements. The
Complete Psionic (2006) book introduced three new standard classes as well as several prestige classes for the psionic character. It also includes a variant Psion class called the "Erudite" which does not have to specialize in a specific discipline. It also has the ability to learn an unlimited number of powers but can manifest a limited few each day.
Complete Psionic also introduced a number of minor rules changes and clarifications.
4th Edition The
Player's Handbook 3, published March 16, 2010, includes four psionic classes, the ardent, battlemind, monk and psion. Psionic powers are called disciplines. Monks use the same general system of at-will, encounter and daily attack and utility powers, while the other three classes lack encounter attack powers, instead possessing a pool of
power points which they can use to augment their at-will attack powers.
5th Edition On July 6, 2015, Wizards of the Coast published an
Unearthed Arcana article on their website introducing a playtest version of new psionics rules for 5th Edition D&D. The article also describes a new psionic class, the Mystic, which could resemble one of several different psionic classes from past editions, depending on the player's choice of Psionic Order. An online survey was conducted to gather feedback from the community, and on September 11, Wizards reported that the core rules were "a good start," but the Mystic class could use greater flexibility. An
Unearthed Arcana article published on April 14, 2020, explained that despite positive response from some fans, the Mystic class was removed in favor of options for existing classes to use psionic powers. The three psionic subclasses were outlined in the 2019 article in
Unearthed Arcana introduced psionic sub-classes for the
Fighter,
Rogue, and
Wizard. Two Third Edition classes, the Psychic Warrior for Fighters, the Soulknife for Rogues were brought back as
subclasses, and a new psionic Arcane Tradition was created for
Wizards. This playtest also included several new psionic-flavored spells and feats. Designers continued to revise the psionic rules releasing another playtest in an
Unearthed Arcana article published in March 2020. The revisions kept the Soulknife as a Rogue subclass, changed the name of the Psychic Warrior to the Psi Knight, and dropped the Psionics Wizard subclass in favor of a new,
Sorcerer subclass called the Psychic Soul. It also included new spells, feats, and features for each. A new Psionic Talent Die was included which would gradually grow in size as a player levels up, and offer either increases in damage, or other mechanical augmentations to a psion's powers. At their online gaming event
D&D Celebration Wizards' of the Coast revealed that the upcoming supplement ''
Tasha's Cauldron of Everything'' would include a new take on Psionics. ==Psionic classes==
