Featured Cosmere RPG Resources
Version 2.0
Originally released at Dragonsteel Nexus 2025
This is a Cosmere RPG one shot designed for parties tier 1 - 2, thought it can be adjusted to suit your needs.
Scouts have detected an unexpected sight: signs of a large signal fire off towards the north end of the Shattered Plains. While investigating, the scouting party was chased away by a group scouts from the enemy. We assume they’re trying to track down the same mysterious signal.
Whatever is out there, we need to beat the enemy to it, and so we’re sending in your team. Find whoever started that signal fire, and why. If there is an advantage to be gained out there on the plains, it is your mission to bring it to bear against the enemy.
Included in the download:
Adventure PDF for game masters
Trashheap city map
Shattered Plains hexcrawl map
Plateau battlemap
Trashheap entrance battlemap new in version 2.0
To run this adventure, you’ll need:
Stormlight Handbook
Stormlight World Guide, though you can swap out adversaries for stat blocks you have if needed.
The map features a winding road that travels around a lait carved out from a crem-lined wall, presumably somewhere near the Shattered Plains, but really you could run it anywhere.
I wanted to capture the look and feel of Rockbuds and other fauna finding anywhere it can in the shelter the rock embankment creates. This was really inspired by the scene in Words of Radiance when Shallan finds a similar lait, and explore the life teaming within.
A pack of chasm battlemaps that can link together to make an infinitely saleable chasm dungeon or endeavor.
Simply use the square maps as tiles, connecting as many as you need to create the map that best fits your campaign.
The download includes:
2 way pass
3 way intersection
4 way intersection
Dead end
Open space
Every adventuring party needs a learned scholar, and what better way to expanded ones own mind than burying that brain in a book. This unofficial rules expansion for the Cosmere RPG gives players the means to grow their arsenal of expertise by reading books in their downtime.
This is no simple task however: players will need to dedicate hours of downtime studying each volume, but they will be rewarded for their diligence and scholarship. Completing and mastering a book grants in game Expertise and other bonuses, increasing the knowledgebase of the player.
In additional, there is the Avid Reader talent tree, designed to push those looking to master the subtle art of studying to the max.
