Everything You Need to Play the Cosmere RPG!

The Stormlight Campaign Setting Core Rules

The Stormlight Handbook is a gorgeous 385-page hardcover book containing all the rules that every player or GM needs to build characters and adventures in the world of Roshar!

An Original, but Familiar System

The Cosmere RPG uses an original system designed for a wide range of players, from roleplaying novices to avid TTRPG hobbyists. The system's core mechanic is simple: roll a d20, add a relevant skill, and try to beat a certain difficulty number.

The Plot Die

When a character attempts something risky or dramatic, the GM can tell them to "raise the stakes." The player then adds the plot die to their d20 roll. This is a special die that can add an Opportunity or Complication to the result of a skill test.
