Best For

Groups who want mouse-scale sandbox adventures where clever plans and careful supplies matter more than fighting. The rules support exploring dangerous ruins and returning treasure to a safe settlement.

Core Mechanic

Roll a d20 equal to or under STR, DEX, or WIL to avoid a risky consequence. Attacks deal weapon damage directly, reduced by armour. Items and conditions compete for limited inventory slots.

ComplexityHow much there is to learn
Low

Attribute saves and direct damage make the core rules quick to learn. Most additional rules concern inventory pressure and spell usage. Exploration and hired help use simple procedures.

Highlights

Condition cards occupy inventory slots, forcing a choice between carrying supplies and enduring setbacks. Spell tablets trade greater power for faster depletion and dangerous miscasts. Faction goals advance between sessions, letting the world change beyond the mice’s immediate adventures.

Considerations

Damage beyond Hit Protection reduces Strength and can incapacitate a mouse after a single failed save. Depleted spell tablets require specific fictional tasks to recharge. Advancement improves attributes and endurance rather than offering classes or extensive ability choices.
