Assist
Leaky-Eye Luca
Luca's assist form can be used in both the Action Battle and Tactical Battle game modes. He has a 3 star assist, and a 4 star assist, both of the 'Fighting Spirit' type. His 3 star assist does not include an assist ability, as 3 star assists only function as stat boosts for the playable statue they are equipped to. Like all assist characters, when the active assists link together, his assist ability may provide extra effects (Action Battle mode only).
