Sephiroth: This ain be easy
Keep hitting the he** outta him,When u get his first hp bar down,then he starts using Sin Harvest : When his hands lights up,Before he ,does this,He'll Run at u and Teleport,Use Strike Raid: DO NOT LET HIM CAST SIN HARVEST,or it will drain ur hp to 1 and drain all ur mp,if i u cant prevent him,Use Strongest potion FAST,cause after he uses Sin harvest,he Atks and that ends in defeat,
When u do some more damge he will Say : starts Hyper slashing with his sword,hard 2 advoid,but heal heal and heal,Then When he Saids "I Am The Chosen one" Run away or circle Around him,Jump and guild cause he will drops Meteors that will Rotate Then Explode,After this atk,he starts moving faster,He will Drop orbs,and Uses a cyclone atk.Advoid if possible and keep atking,this is all i knwo for now,And watch out for his sin harvest
