Prestidigitation

Perform a harmless minor magical trick: clean or soil an object, chill, warm, or flavor nonliving material, light or snuff a candle, create a small sensory effect, mark a surface, or create a Tiny nonmagical trinket or illusion that lasts until the effect ends.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
