Backward-compatible with 3.5 fantasy rules but offering new solutions and options that place it firmly on the cutting edge, the Pathfinder RPG is the culmination of the largest open public playtest in RPG history. The Pathfinder Roleplaying Game Core Rulebook includes revised rules for the classic seven fantasy RPG races, updated options for the 11 core classes, an overhauled experience system, and a streamlined skill system, plus a host of new and familiar feats, equipment, combat options, domains, specialty schools, new and revised spells, and updated rules for NPCs, including quick-generation rules.
