Core Mechanic

Skill Check — roll d10, add your level in the relevant Skill plus half the matching Stat Bonus (a stat's value minus 10), and meet or beat a difficulty from 1 (Very Easy) to 19 (Nearly Impossible). Attacks instead roll d20 plus a weapon's hit bonus against the target's Evasion. Combat runs in rounds where each character spends three Action Points per turn, with an attack costing two and a natural 20 adding bonus damage. The GM awards Narrative Momentum for inventive roleplay, which players spend together with Action Points on Cinematic Actions — freeform stunts resolved at the GM's discretion.

Best For

Groups who want maximal character customization in a free, setting-agnostic system — players who enjoy assembling a bespoke concept from a huge option pool and a GM willing to supply the world the rules deliberately leave blank.

Highlights

Characters are assembled from ten Archetypes, more than 210 Sub-Archetypes, over a thousand Abilities, plus Paths, Talents, and Traits, giving a single concept many independent axes of mechanical customization. Abilities draw on a Willpower pool, and spending extra Willpower upcasts them on the fly — scaling effects like damage, area, targets, or duration up to a per-tier limit — so one ability flexes to the moment instead of being a fixed effect. Every feature carries a complexity rating from 1 to 4, and Beginner Traits, a Cinematic Rules mode, and thirteen alternative-rule modules let a group run the same engine as a rules-light game or a dense tactical one.

Considerations

Character creation draws from over a thousand abilities plus hundreds of talents and traits, so building a character means selecting from a very large catalogue rather than a curated short list. The system is setting-agnostic and ships with no default world, so a group must supply or adapt a setting before the customization options mean anything in play. Skill checks and attacks resolve on separate scales — d10 plus half a Stat Bonus for skills, d20 plus full bonuses against Evasion for attacks — so the two halves of the system use different math players must keep straight.
