How to beat Sephiroth in Kingdom Hearts??

bạn are talking about Kingdom Hearts I and not II right?I will give bạn both answers.First bạn must have plenty of Elixirs hoặc Hi Potions with bạn because the "Descend Heartless Angel" di chuyển leaves bạn with 1 HP and no magic!!!No magic means no Cure and no Cure means no thêm HP.You can stop his spell before he casts it bởi hitting him!In Kingdom Hearts II bạn need the Aerial Dodge ability (you get that after leveling Master Form [Master Form levels up when bạn get Drive Orbs]) to reach him.In Kingdom Hearts I bạn must be lucky enough hoặc Sephiroth be fool enough to teleport behind bạn before he cast the spell.If he casts the spell go away from him as far as bạn can and give a Hi Potion to yourself.Better have it in the shortcut menu.Hope I helped ;)
