The Expanded Psionics Handbook is a sourcebook written by Bruce Cordell for the 3.5 edition of the Dungeons & Dragons fantasy roleplaying game that contains rules and options for integrating psychic powers (also known as psionics) into the game. Along with its predecessor, the Psionics Handbook, the Expanded Psionics Handbook expands and adapts the psionics concept with a new emphasis on balance and playability. Source: Wikipedia (en)
