Paizo Publishing has opened the playtesting period for its Pathfinder RPG Advanced Player’s Guide, which is scheduled to release in August 2010 (see “Pathfinder Advanced Player’s Guide”). 


The first two of the six complete 20-level base classes planned for the Pathfinder Advanced Player’s Guide (Cavalier and Oracle) were posted online for open playtest on November 13th.  Summoner and Witch will be posted on November 30, and Alchemist and Inquisitor will be posted on December 14. 


Paizo used playtesting extensively when prepping its initial Pathfinder RPG products for release.
