The Pathfinder GM Core is the second core rulebook for the fully revamped Pathfinder Second Edition RPG. These rules are compatible with the previous rulebooks of the second edition of Pathfinder, incorporating extensive corrections and rule updates, as well as some of the best additions from later books into new, more accessible volumes with fresh presentations inspired by years of player feedback.

Together with the Player Core, Monster Core, and Player Core 2, these books provide a new foundation for the future of tabletop gaming.
