Paizo will release the Pathfinder Roleplaying Game:  Advanced Players Guide at $39.99 for Gen Con 2010.  The 320-page full color hardcover, conceived by Pathfinder lead designer Jason Bulmahn and with a cover by Wayne Reynolds, was developed using the input of the thousands of gamers who took part in the open playtest phase of the Pathfinder RPG development. 

The Advanced Players Guide includes six completely new 20-level character classes, including the Alchemist, the Cavalier, the Inquisitor, the Oracle, the Summoner, and the Witch.  It also includes expanded rules for the eleven core classes, new feats and combat abilities, equipment, and dozens of new spells.
