🌩 The World of Roshar — Quick Reference
🌪
The Highstorms

Massive continent-spanning storms that sweep Roshar from east to west. They carry Stormlight — the magical energy that powers fabrials and fuels Surgebinding. All Rosharan life evolved around them: plants retract into stone shells, creatures grow armored carapaces, and cities build thick eastern walls. The storms also summon spren and recharge spheres used as currency and light sources.

Spren & Stormlight

Spren are spirits — manifestations of natural forces, emotions, and ideas. Ordinary spren appear near fire, wind, and fear. Sapient spren of higher concepts can bond with humans, transforming them into Knights Radiant. Stormlight is the lifeblood of Roshar's magic: breathed in from spheres, it heals wounds, powers Surges, and sustains a Radiant's bond with their spren.

Shardblades & Shardplate

The legendary weapons and armor of the Knights Radiant, now scattered across Roshar. Shardblades are summoned from mist after a 10-heartbeat count and can cut through any non-living material, severing the soul from the body. Shardplate is impenetrable armor that enhances strength and speed. Possessing a Shard makes a warrior nearly unstoppable — and dynasties have been built on their ownership.

🏔
The Shattered Plains

A vast landscape of raised plateaus separated by deep chasms in southeastern Roshar. The site of an ongoing war between the Alethi highprinces and the Parshendi. The terrain — broken into hundreds of plateaus by an ancient cataclysm — makes every military movement a careful bridge-running operation. The Plains are also home to the massive Chasmfiend creatures, hunted for their gemhearts.

⚡ The Knights Radiant — Orders of Surgebinders

Each Order of Knights Radiant bonds a specific type of spren and gains access to two of the ten Surges — the fundamental forces of Rosharan physics. In the Cosmere RPG, Radiant Paths unlock at level 2 and require speaking the First Ideal of your Order.

🎲 How the Cosmere RPG Works
The Core Roll
Roll a d20, add a relevant skill bonus, and meet or beat a Difficulty number set by the GM. Familiar to any D&D or Pathfinder player — but with meaningful upgrades throughout.
The Plot Die
Add a special d6 to any dramatic or risky roll to "raise the stakes." The result introduces a Complication or Opportunity — a narrative twist that makes every roll a potential story moment.
Fast & Slow Turns
Each round you choose your initiative slot. Take a Fast Turn and act first — but only get 2 actions. Take a Slow Turn and wait — but earn 3 actions. Tactical, cinematic combat every round.
Heroic Paths
Choose one of 6 starting paths at level 1: Warrior, Scholar, Leader, Scout, Artisan, or Diplomat. Each opens a talent tree of branching abilities — no multiclassing penalties, ever.
Radiant Paths
At level 2+, swear the First Ideal and bond a spren to become a Knight Radiant. Unlock Surgebinding skills, Breathe Stormlight to fuel powers, and speak further Ideals to gain strength.
Investiture
The resource that fuels all supernatural abilities. Radiants spend Investiture to use Surges. Breathe in Stormlight from spheres to replenish it mid-combat. Non-Radiants start with no Investiture pool.
Ancestries
Play as a Human (bonus Heroic talents as you level) or a Singer — the shapeshifting Listeners. Singers access unique form-changing talent trees that grant specialized combat and social abilities.
Conversations & Endeavors
Social encounters and skill challenges are fully supported. Wear down stubborn NPCs with successful tests, while they make counterarguments that drain your Focus. Roleplay is mechanically rewarded.
