Killing sephiroth
To defeat sephiroth try to be on lv 70 bring three megalixars and a good keyblade like lionheart. Keep attacking him until his health is gone by one bar then when he runs fast try attacking but when he uses a spell to bring your hp to one and mp to zero.
Then use a megalixer if he uses spell but when he's performing spell go after him and attack him to stop him keep doing this until he loses about two and 1/2 bars then he'll stop and put a spell around him (it does nothing to you) then he'll perform ultima on you.
To advoid his ultima try rolling around him untill he jumps then try to get behind him after that keep attacking until he dies. Use areoga to protect yourself ( it lower oppents attacks while it lasts).
