Luck is a fickle, fluid thing, and that's what these tiny mimics love about it most. Taking the shape of dice, cards, and other gambling sets, these unique aberrations can disperse their bodies into a collection of similar objects. It’s not unheard of for a mimic of chance to shuffle itself into another gambling set, carefully consuming the articles it imitates. GIven its size, the mimic of chance prefers easy meals. It uses its alien mind to influence those playing its game, as it were, to take reckless actions such as cheating or betting more than they should until violence or self-harm occurs. Then it gobbles up the results. From time to time, however, a mimic of chance will bind with a gambler, usually a sardonic corrupt soul. Its nature helps the player amass prestige and wealth, while the gambler ensures that the miniature mimic never goes hungry.
