Mistborn Finally Gets Its RPG Moment With Brotherwise's Cosmere Expansion
Key takeaways
- Mistborn Handbook, Campaign Guide, and Welcome to Scadriel available for preorder; November 4 release date
- Two campaign eras with different level ranges; mechanics emphasize allomancy and ferochemy magic systems
- Cosmere RPG continues expansion after Stormlight Archive books reviewed positively last year
Brotherwise Games is bringing Mistborn to its Cosmere RPG with three new guidebooks launching November 4, all available for preorder on Amazon now. The Mistborn Handbook is the core player resource for building characters and covers the allomancy and ferochemy magic systems unique to the setting. The Campaign Guide adds two distinct story paths—Era 1 (levels 3–6) and Era 2 (levels 3–9)—each designed to echo consequences across centuries within Scadriel's world.
For players unfamiliar with Sanderson's books, the 24-page Welcome to Scadriel guide serves as a visual primer. This expansion follows the successful 2025 launch of the Cosmere RPG's Stormlight Archive books, which introduced the system to strong reviews. While a 2012 Mistborn Adventure Game exists, Brotherwise's version represents the official integration into the broader Cosmere tabletop ecosystem.
The bigger picture
The Cosmere RPG is establishing itself as a serious competitor to D&D 5e for licensed fantasy systems, especially among readers invested in Sanderson's worlds. With Stormlight performing well and Mistborn arriving soon, Brotherwise is building franchise momentum that could eventually expand beyond tabletop into streaming and community play—areas where D&D has dominated. Watch whether additional Cosmere properties follow, and if crossover compatibility becomes a strategic selling point.
We're covering this because Mistborn's arrival signals how successfully authors and publishers are translating literary fanbases into tabletop audiences. The Cosmere RPG matters beyond just Sanderson enthusiasts; it shows that narrative-focused TTRPG systems can compete when they're built on beloved source material and solid mechanics. This is worth tracking for anyone following where tabletop gaming's growth is actually happening.
