Core MechanicRoll d20 + skill vs. difficulty. The GM can raise the stakes on key rolls by adding the plot die: a custom d6 with Opportunity, Complication, and blank faces. Opportunities grant bonus effects chosen by the player; Complications introduce narrative twists chosen by the GM but also add a bonus to the roll. Each combat round, characters choose a fast turn (2 actions, act first) or slow turn (3 actions, act later). Characters advance through branching talent trees across 6 heroic paths and 9 Radiant paths.Make a D20 Test by rolling d20, adding relevant modifiers, and comparing the total to a target number. Ability checks, saving throws, and attack rolls use this procedure. Advantage and disadvantage use two d20s and keep the higher or lower result.

Best ForBrandon Sanderson fans who want deep character customization and hard-magic systems brought to the table: groups who enjoy Pathfinder-level build depth in a richly detailed setting.Groups who want heroic fantasy with configurable tactical combat, broad character options, and campaigns that span multiple levels.
HighlightsDeep lore integration with the Cosmere setting, extensive character customization rivals Pathfinder, plot die adds dramatic tension, fast/slow turn initiative lets players trade actions for turn order, Foundry VTT supportAdvantage and disadvantage resolve common situational effects by selecting the higher or lower of two d20 rolls. Backgrounds, classes, subclasses, and feats distribute character choices across creation and advancement. Weapon Mastery gives qualifying weapon users distinct tactical effects without replacing the action economy.
ConsiderationsPlot die adds a layer of opportunity/complication outcomes on top of pass/fail increasing cognitive overhead per roll, rulebook organization is poor and unclear in places, large barrier to entry for non-Sanderson fans, social encounters can feel repetitiveSpell preparation, spell slots, class features, and conditions create several interacting resources for players to track. High-level characters combine many spells and features, increasing adjudication work for the DM. Bastions add a separate downtime procedure for campaigns that use the stronghold rules.
