Each rarity level have a set of possible outfit combinations that influence gameplay. Mouse Heroes will have 4 different rarity levels: Common, Rare, Epic and Legendary. For each rarity level the Mouse Heroes will have a set stamina bar size that is the same for all the heroes of that rarity. Higher rarities will have bigger stamina bars, meaning they can stay longer in the levels and earn more tokens. Higher rarities will also have an increased number of traits making owning them more advantageous if you're looking for synergy combos to increase your earn rate. The traits distribution is determined by the Mouse Hero outfit and is directly tied to their rarity level.
