1. He is hard. I tried at level 65 and couldnt even take three hits. And since it was a three hit combo, it was as good as one hit. I then beat him at level 84 and was still quite hard. Highlight this blank spot for a good pre-fight strategy, but atleast try yourself first:
Best remove your customized magic except for curaga and reflega, and place elixers (and potions) in your shotcuts if you dont have 6 elixers, you'll need em if he hits the move that reduces HP to 1 and empties your mana. Cast reflega in rapid succession to block his "meteor rain" attack. (I invented that name, you'll know it when you see it, he uses it around 3 HP bars remaining) It's also good to remove your equipped combo plusses since bosses require a finishing move to kill when his HP is one, if you have a long combo he may teleport eveytime you try to finsih him off.
2. It's more fun cuz KH2 has better fighting period.
3. The only reaction against him is used to block one his attacks. This attack has no name unless the strategy guide says it does. You have about 2 seconds to do it and if you dont, half your life or more is gone no matter what. He basically rushes through you and damage is dealt a second after he hits you, like one of those samurai movies or somethin.
