From publisher blurb:
New options for ardents, battleminds, monks, and psions.
Hot on the heels of Player’s Handbook 3 comes Psionic Power, a D&D supplement that explores the psionic power source in more detail. This supplement presents hundreds of new options for D&D characters, specifically focusing on heroes who channel the power of the mind. It provides new builds for the ardent, battlemind, monk, and psion classes, including new character powers, feats, paragon paths, and epic destinies.
