Brandon Sanderson and Brotherwise Games have been developing tabletop games based on the Cosmere universe since 2020. Last year, they launched the first core rulebooks for a full Cosmere RPG after a successful crowdfunding campaign. In 2026, they've released an eagerly anticipated Mistborn expansion, available for preorder on Amazon with a November 4 release date.
The Mistborn Handbook, Campaign Guide, and Welcome to Scadriel guide are included in the preorder package. The handbook is crucial for understanding the basics of the RPG, while the campaign guide helps GMs create a realistic setting from the books. Players can choose to play through two eras, with Era 1 suitable for levels 3-6 and Era 2 for levels 3-9.
A 24-page welcome guide is also available for beginners to familiarize themselves with the Cosmere world before diving into the game. This expansion is Sanderson's second attempt at a Mistborn TTRPG, following the Mistborn Adventure Game from 2012, which was later overshadowed by the Brotherwise Games Cosmere RPG.
