Pathfinder GM Core is the second core rulebook for the fully remastered Pathfinder Second Edition RPG! These rules are compatible with previous Pathfinder Second Edition rulebooks, incorporating comprehensive errata and rules updates and some of the best additions from later books into new, easier-to-access volumes with new presentations inspired by years of player feedback. Along with the Player Core, Monster Core, and Player Core 2, these books provide a new foundation for the future of tabletop gaming!
