Core MechanicRoll 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.Combat uses standard d20 + class attack bonus + ability modifier vs. Armour Class. Out of combat, attribute checks roll equal-or-under (1d20 ≤ attribute, with degrees of success), and skills add +1 and grant access to a level-based Reroll Pool that smooths the d20 swing. Dropping to zero hit points triggers an All Dead vs. Mostly Dead check and a roll on the Injuries & Setbacks table (lost eyes and limbs, broken ribs, madness, permanent scars). Spell casting is uncertain: every cast carries a cumulative 1-in-20 chance of triggering the Dark & Dangerous Magic d100 table, which can mutate the caster, sap Luck, or summon hostile aberrations. The Luck attribute itself is a depleting meta-resource that fuels saves, Major Exploits, and Rescue Exploits.

Best ForGroups 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 gritty low-magic fantasy where every combat carries real consequences (broken bones, lost limbs, madness) and where casting a spell is a calculated gamble that can corrupt the caster or summon something worse.
HighlightsAdvantage 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.Dark & Dangerous Magic puts every spell at risk of triggering a d100 corruption table (mutations, summoned aberrations, Luck loss, madness) with the chance climbing by 1 in 20 each cast until it fires, making sorcery a calculated gamble rather than reliable utility. Martial Exploits layer creative combat moves (Minor, Major, and Rescue) on top of a successful hit, such as disarms, decapitations, or throwing an ally clear of a fireball, fueled by depleting Luck checks rather than a fixed action menu, so combats are improvisation-driven rather than rotation-driven. Every PC designs a Unique Feature at 3rd, 6th, 9th, and 12th level in conversation with the GM, working off 36 worked examples (Awakened Host, Faustian Pact, Skill Prodigy, Slippery Bastard) that each scale through low, moderate, and high power tiers the table can cherry-pick.
ConsiderationsHigh-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.Magic Users are deliberately weaker than other classes: no at-will spells, no teleport, no mind reading, no resurrection, and every cast risks a corruption effect, so spell-focused players have to accept playing a high-risk role that can lose its toolkit mid-adventure. The 12th-level cap shortens the campaign arc: the book trades long-haul progression for keeping monsters threatening and magic spectacular, but groups expecting decades-long advancement curves will hit the ceiling. Permanent injuries from the Injuries & Setbacks table are a regular outcome of going to zero hit points, and short of rare in-setting healing magic those disabilities stay, which can frustrate groups attached to keeping their characters physically whole.
