Lucky Strike

Lucky Lucky is an ability that Sora, Donald and Goofy, as well as a few extra characters, can equip in Kingdom Hearts (called 'Lucky Strike') and Kingdom Hearts II. The ability, as its name may suggest, increases the overall drop rate of items during battle. The more characters that have this ability equipped, the better the chances of receiving the items. The Genji Shield, Meteor Staff and Sweet Memories Keyblade come with this ability in Kingdom Hearts II. They are part of the Seven Lucky Lucky combo.

The activation cost of the learned ability is 2 AP in Kingdom Hearts and 5 AP in Kingdom Hearts II.
