Hay, I am a little stuck on this one part. I am on mission 50 and have plenty of magic and potions. I can not seem to defeat the boss. My current method is throwing fire and ice magic at him when his mouth opens. I stay on the side until he throws those multiple balls at me. I knock back the fire attacks into the heartless on is head until one is left. But, by the time I run out of potions and magic, he still has three sets of life left. Am I doing this correctly? Also, any advice on the colloseam thing, in the third one, I finish with 9/100.....
Update: Well, I took the obvoise solution and tryed it again with more potions. =P Thank you for nothing I guess.
