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.Roll d20 + modifier against a target DC (for ability checks and saving throws) or AC (for attacks). Meeting or exceeding the target succeeds. Advantage rolls 2d20 and takes the higher; disadvantage takes the lower, replacing most situational modifiers.

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 adventures with tactical grid combat, deep character customization, and access to more published adventures and supplements than any other RPG.
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/disadvantage system simplifies most situational modifiers to a single mechanic. Extensive class and subclass options across 12 base classes with 48 subclasses in the 2024 PHB. The largest third-party content ecosystem in tabletop RPGs. Free basic rules and starter sets lower the barrier to entry.
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 repetitiveHigh-level play (tier 3-4) introduces significant spell interaction complexity and encounter balancing challenges for GMs. No official rules for non-fantasy genres. Three core books at $50 each represent a significant investment for the full rules.
