How do you beat the Leechgrave in Kingdom Hearts 358 2 days?

Answer 1

Stay on top of the ruins until it runs into the building and hit it until it starts moving again. It will go up in a whirlwind and send boxes at you. Hit them back to stun it for a while and hit it. Repeat until it is defeated.

Answer 2

kill all the tentaclaws then it will fall and just start wailin on it till it falls again, btw magic wont affect the leechegrave so save that for the tentaclaws
