| 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. | G.U.T.S. (General Understanding of The System): sum 3d8 and try to roll equal to or under your Trait Level (starts 8, capped at 17). The margin of success or failure is called the Success Level or Failure Level and scales the effectiveness of the action. Knack Mastery shifts the effective trait by −4 (Untrained) to +2 (Master). Difficulty adjustments (Very Easy to Very Hard) add or subtract 4 to 2 from the trait. |

| Best For | Groups who want heroic fantasy with configurable tactical combat, broad character options, and campaigns that span multiple levels. | Groups who want a comedic high-fantasy adventure with mechanical breadth (mastery-tiered skills, three magic schools, twin crafting paths) paired with a simple roll-under core. Characters are sworn Members of a Guild taking hired contracts in the kingdom of Yogath, often unknowingly working for the Crown or a shadowy Consortium plotting against it. |
| 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. | Rolling doubles on an attack triggers weapon-typed Status Effects (swords impale, blunts stun, axes amputate), so weapon choice shapes battlefield complications, not just damage. Mages can attempt spells above their Mastery tier, but a failed overcast rolls on a Miscast table that can escalate to a Wild Magic explosion damaging the caster and nearby allies. Elixirs grant a temporary trait buff offset by a matching Withdraw penalty once combat ends, making potion timing a tactical trade-off rather than free power. |
| 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. | Weapon-typed Status Effects, weather penalties, and per-weapon damage tables add table-reference overhead during combat. The comedy-grim tone (Goblin Piss Paste as a crafting ingredient, an Iron Pan spell cast by yelling 'I cast iron pan!', a Mad Child King on the throne) will not fit groups expecting straight high-stakes fantasy. Adventures are built around Guild Contracts in the kingdom of Yogath, so dropping into a homebrew setting means reworking the Crown and Consortium hooks that drive published material. |
