Best For

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.

Core Mechanic

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.

The core sums 3d8 and rolls under a trait level, with the margin setting success. The depth is the build of Knacks, Talents, and Spells over a combat layer with status effects. Travel and inventory rules round it out.

Highlights

  • 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

  • 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.
