I would say level more, he is not that hard but I ended up waiting until I was level 100 to ever fight him. You can probably grind that out in just a few hours if you have the last form yet (the name slips me atm, final form maybe? The one where you fly around and stuff), it makes leveling go by so fast. But eh, I would say just get the ultimate keyblade. If you are level 50 chances are you are near done or done with the game anyway I imagine?

I'd suggest waiting until you reach level 80. It'll be a lot easier to beat him then... but it'll still be hard as balls. But it all depends on your skill level too. Have lots of ether and potions on you too.

So I said in my last blog post I'm trying to finish the end of Kingdom Hearts 2 and I managed  to get to level 50 so far.  I also stated that i wanted to get sephiroth's keyblade, I though level 50 would be enough, but i was killed in probably around 5 hits so i have decided to grind to level 60 and try and beat him, but  Is there anything else I should be doing?
