Forum:Help in KH

Hey all its Jon again :) Hope everyone is doing alright. I'm having a lot of trouble defeating a boss in Kh1 in Agrabah. It's that giant Heartless that appears on the way to the Cave of Wonders; i've learned his pattern and everything but he always kills with me with that spinning thecnique grrr. i'm LVL 62 and have decent magic and health and Oblivion but he still always kills me. If anyone knows how to beat it can you tell me please? Thanks and have a good day.
