Best For

Groups who want a genre-agnostic d10 dice pool engine with dedicated subsystems for action, investigation, and social intrigue: especially those building their own setting or adapting existing Storypath games.

Core Mechanic

Roll a pool of d10s equal to Skill + Attribute. Each die showing 8+ is a hit; 10s count as two hits. Add Enhancement (bonus hits from gear, abilities, or circumstances). Spend hits to meet the difficulty, buy off Complications (side effects attached to the roll), or purchase Tricks (extra effects like knockdown or critical hits). Failed rolls generate Momentum, a shared pool players spend for bonus hits, to turn failures into successes, or to introduce story facts.

Roll a pool of d10s from skill plus attribute and count 8+ as hits, with Momentum to spend. The depth is action-adventure combat plus an Influence system for social play. Crafting and heist rules extend the same dice engine.

Highlights

Three distinct play modes (action-adventure, investigation, and influence) each with dedicated mechanics. Complications and Tricks give every successful roll narrative texture beyond pass/fail. Momentum turns failed rolls into a shared resource that keeps the story moving. Modular building-block systems (powers, heists, vehicles, crafting, large-scale combat) plug into any game.

Considerations

No included setting beyond three short examples: groups must build or adapt their own world. No free quickstart or SRD available. Multiple interacting subsystems (Enhancement, Advantage, bonds, Complications) take several sessions to internalize.
