Lucky Strike

Lucky Lucky (ラックアップ), also translated as Lucky Strike in Kingdom Hearts and Kingdom Hearts 358/2 Days, is an ability which appears in Kingdom Hearts and Kingdom Hearts Final Mix, Kingdom Hearts II and Kingdom Hearts II Final Mix, and Kingdom Hearts 358/2 Days. In all games, it increases the drop rate of items, and in Kingdom Hearts and Kingdom Hearts II, this effect can be increased by equipping multiple copies of the ability. In Kingdom Hearts, "Lucky Strike" requires 3 AP to equip, while in Kingdom Hearts II, "Lucky Lucky" requires 5 AP.

In Kingdom Hearts II, there are a maximum of seven Lucky Lucky's that can be equipped (the four belonging to the Sweet Memories, Meteor Staff, Genji Shield, and Lucky Ring, and the three belonging to the party characters). As the Lucky Lucky abilities stack exponentially, this results in an enemy's base drop rates being multiplied by 627.5%.

In Kingdom Hearts II Final Mix, Lucky Rings can in fact be synthesized, and in "Critical Mode", Roxas starts with two additional Lucky Lucky. However, Lucky Lucky was removed from the weapons which previously contained it, so only seven additional Lucky Lucky can be equipped, for a total of fourteen. Furthermore, the boosts from Lucky Lucky stack linearly instead of exponentially, so this results in a drop rate increase of only 800%. As compensation for this, Sora has an additional Lucky Lucky in Limit Form, which can raise the drop rate increase to 850%.
