| Core Mechanic | Roll 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. | Build a d10 pool from an Attribute plus an Ability and count each die that meets or exceeds the difficulty, usually 6. Each rolled 1 cancels a success, and a roll with no successes and at least one 1 botches. Magick uses Arete instead: the highest Sphere plus coincidence or vulgarity and witnesses establishes the base difficulty, with situational modifiers applied afterward. Successes determine the Effect, and vulgar casting risks Paradox. |

| Best For | Brandon 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 long-form modern occult campaigns about reality-shaping power, ideological conflict, and the consequences of imposing belief on the world. |
| Highlights | Deep 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 support | Nine Spheres combine to build open-ended Effects, allowing the same capability to emerge through different paradigms, practices, and instruments. Coincidental and vulgar classifications make subtlety a tactical choice because conspicuous magick raises difficulty and accumulates Paradox. Focus ties belief to procedure, so a mage's worldview determines the tools and rituals used to alter reality. |
| Considerations | Plot 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 repetitive | Improvised Effects place frequent adjudication on the Storyteller, who must apply Sphere permissions, focus, required successes, and consequences consistently. Vulgar magick generates Paradox even on success, so overt power can punish a mage through injury or metaphysical breakdown. Faction choices can make a cabal internally hostile, so character concepts need shared motives before play. |
