| Core Mechanic | 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. | Roll a pool of d6 equal to the stat tied to the skill and count successes, with each die succeeding on 5–6 when Untrained, 4–6 when Trained, and 3–6 when Mastered. The number of successes must meet or beat a Difficulty Value set by the Gamemaster. Bonus and penalty dice adjust the pool. A penalty die that rolls 5–6 cancels a success. Opposed checks compare success counts instead of a fixed Difficulty Value. |

| Best For | Groups who want heroic fantasy with configurable tactical combat, broad character options, and campaigns that span multiple levels. | Groups who want gothic-horror monster-hunting and investigation on a contract-driven mission structure, where characters carry a permanent curse that escalates as they lean on their powers. Also supports solo or GM-less play through the built-in Lone Hunter rules. |
| Highlights | Advantage 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. | Each of the twelve Marks grants a supernatural Boon paired with a Curse that advances a stage every time the hunter runs out of Resolve, so power comes bundled with an escalating personal cost. Influence earned by bluffing, charming, or intimidating a faction accumulates as a spendable resource that buys concrete favors from four rival powers, turning social play into a persistent currency. A full Lone Hunter mode replaces the Gamemaster's difficulties with a success-tier table and twist tables, letting the same character and dice run solo without a separate ruleset. |
| Considerations | Spell 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. | A hunter's Mark is chosen at creation and can never be changed, locking in both its Boon and the eventual monstrous transformation the character is fated toward. The setting leaves its central mysteries, including the nature of the Bitter Sacrament and the buried ympir, deliberately unanswered for each Gamemaster to resolve or not. Most antagonists are Minions that never roll to Parry, Dodge, or Counterattack, so rank-and-file fights reduce to attackers rolling against a fixed number instead of opposed checks. |
