The Player’s Handbook 3 is the newest core release for 4th Edition Dungeons and Dragons that introduces a lot of new content including the psionic power source. In much the same way the PHB2 introduced primal classes with a back story, this book lays out the changes to any D&D world that might bring about psionic characters and races. If you’re a fan of psionics, miss rangers that could cast natural spells, want to play classes that are more versatile and flexible, or if you’re just looking for some new options for your 4th edition game you really should check out this book.
