Lucky is a positive status effect and a battle mechanic that appears in Sonic Chronicles: The Dark Brotherhood.
In gameplay, when a target is affected by Lucky, his/hers Luck is increased. A few rounds after the target has been given Lucky, however, it will wear off. Targets with the Lucky status effect are signified by green four-leaf clovers emitting from their body.
Lucky can be given to a playable character by using Clover Juice.
