I played KH1 for the first time in like 1year just to beat Sephiroth..

I used the Lionheart keyblade,only magic i used was Cura,and I had alot of elixirs equiped...alot..
also i deactivated all the Combo Pluses and only ability i used was strike-raid..
took me like 4 tries to get the hang of it..
umm good luck..=D
