| Core Mechanic | 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. | 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 combining tactical grid combat with deep character-build options, scaling from one-shots up through long multi-tier campaigns. | 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 collapse most situational modifiers into one mechanic: roll a second d20 and keep the higher or lower, so play rarely stops to total small bonuses. Each of the 12 classes offers four subclasses in the 2024 Player's Handbook, letting players reshape a class's role without multiclassing. Bounded accuracy keeps proficiency bonuses small, so low-level threats stay relevant in numbers and DCs read consistently across all tiers. | 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 | High-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. | 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. |
