Mouse Boons: Positive Conditions for Mausritter

A set of 30 positive conditions for player mice in Mausritter. The GM can award boons after difficult combat, heroic feats, or other notable achievements. Each boon occupies one inventory or grit space and must be activated by the player as an action during combat. Activated boons are removed from inventory or grit and remain in effect until cleared, with a maximum of two active boons per player. Effects support combat and exploration, and can be adjusted to suit the campaign.
