Cosmere RPG - Mistborn Handbook

The Mistborn Handbook is a gorgeous 405-page hardcover book containing all the rules that every player or GM needs to build characters and adventures in the world of Scadrial!

Mistborn Era 1 offers a dark fantasy world of heists, horror, rebellion, and ballroom intrigue. Era 2 adds pulp adventure, secret societies, and gunslinging action. In both eras, heroes face personal battles while defending the world from the influence of nefarious gods. When you’re ready to become a game master, uncover more secrets with the Mistborn World Guide and the Mistborn Legacy adventure.

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.

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.
