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 an Attribute-plus-Ability pool of d10s and count dice meeting the difficulty, usually 6. Each rolled 1 cancels a success. A roll botches only when no die meets the difficulty and at least one die shows 1. Magick instead rolls Arete, the mage's enlightenment rating, against a difficulty based on the highest Sphere used and whether the effect violates ordinary reality. Successes determine the effect's extent.

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 long modern occult campaigns about conflicting beliefs and the consequences of reshaping reality.
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.	Nine Spheres combine into improvised magical effects beyond a fixed spell list. A mage's beliefs determine the practices and instruments that make those effects possible. Concealing magick within plausible events reduces the risk of reality's backlash.
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.	Improvised magick requires the group to agree on what an effect can accomplish before rolling. Accumulated Paradox can injure a mage or trap them in a distorted reality. Cabals need shared motives to keep incompatible faction loyalties from pulling the campaign apart.
