Lucky Strike
Lucky Lucky is an ability that Sora, Donald and Goofy, as well as a few extra characters can equip in Kingdom Hearts II. The ability, like it's name suggests, increases the overall drop rate of items during battle. The more characters that have this ability equipped, the better chance at getting better items. The Genji Shield, Meteor Staff, and Sweet Memories Keyblade come with this ability. They are part of the Seven Lucky Lucky combo.
