Core Mechanic	Decrease Dice: each character has one die, starting at d20, that serves as both their health and their resolution roll. To attempt a risky action, roll the die against the Difficulty your class assigns that skill; meeting or beating it succeeds, while a normal failure costs only the attempt. The die steps down a size (d20 → d12 → d10 → d8 → d6 → d4) whenever you roll a 1, take major damage, or voluntarily force the scale to convert a failure into an automatic success. A character whose die would drop below d4 falls Exhausted or dies; sleeping in a safe shelter resets it to d20 and consuming a sugar ration steps it back up one size.	Roll d100 under skill or characteristic. Success Levels measure degree of success by comparing the tens digits of the target and the roll. Advantage accumulates during combat, adding +10 per point to attack tests.

Best For	Groups who want a quick, comedic one-shot or short campaign as thumb-sized survivors scavenging a household that has become a hostile wilderness, with a ruleset light enough to read in a few minutes before the first session.	Groups who want dark, gritty fantasy where ordinary people face extraordinary dangers in a richly detailed setting. The career system creates unique character arcs from rat catcher to witch hunter.
Highlights	The Decrease Dice mechanic collapses health and resolution into a single die, so every roll both tests the action and visibly wears the character down as the die shrinks toward d4. Forcing the scale lets a player turn any failure into a guaranteed success by stepping their die down a size, making each clutch moment a deliberate trade of long-term stamina for an immediate result. Monsters are rated by a Threat Die that attacks and spells whittle down, and several (the chitin-armored cockroach, the static-charged dustbunny) shrug off ordinary weapons until players expose a weak spot or switch to fire, water, or magic.	The career system structures advancement around trades, moving a character through jobs that shape both skills and story. Success Levels measure how far a d100 test beats or misses its target, turning every roll into a degree of result. Advantage accumulates during a fight, rewarding momentum with stacking bonuses to attack tests.
Considerations	Combat has no initiative or turn order (the GM narrates enemy intent and players react with defensive rolls), so there is little structure for tactical positioning. Rolling a 1 on any skill check (including routine Stealth, Alertness, or social rolls) steps the die down the same as taking a hit in combat, so avoiding unnecessary rolls becomes a survival strategy rather than a purely narrative choice. There is no advancement system: skills are fixed at character creation and the Decrease Die only ever recovers to its starting size, so characters do not grow mechanically over a campaign.	The rules assume the Old World setting, so moving WFRP elsewhere means reworking its careers and tone. Comparing tens digits for Success Levels on every test adds a math step that can slow combat. Advancement is career-gated, so a character often must finish or leave a career before branching into new skills.
