Psionics (Dungeons & Dragons)

In the Dungeons & Dragons fantasy role-playing game, psionics are a form of supernatural power similar to, but distinct from, arcane and divine magic. Psionics are manifested purely by mental discipline. Psionics were introduced in the original supplement Eldritch Wizardry. Psionics have appeared as part of the core rules beginning with Advanced Dungeons & Dragons 1st edition.
