Call of Cthulhu RPG: Keeper Rulebook

The core book. If your group is playing Call of Cthulhu, someone at the table owns this.

The Keeper Rulebook is the complete 7th Edition ruleset — everything needed to run the game, written for the person doing the running. Full rules for skills, combat, chases and the Sanity system that has defined the game since 1981, plus the Mythos itself: the entities, the tomes, the spells, and guidance on using them without spending the whole thing in one session.

It also includes advice on constructing scenarios and campaigns, and a starting adventure. Chaosium's 7th Edition is the version in print worldwide and the one most published scenarios are written for.

Perfect for: Keepers. This is the book you run the game from.
