i need help.... i cant defeat sephiroth on kh1,i get up to sin harvest and then die.i need to know if i should attack hardly ever and stay safe or just attack and dont stop intill i can heal....i need help pleeeeeeeeeease!

What level are your characters?

well,i think goofy is level 65 and i think donald is 70,im level 67 and i use the oblivian,ars arcuman,raganork and i cant get magic back when he says "SIN HARVEST" and u loose ur health and magic...

To stop the sin harvest you need to interrupt it. Sephiroth will teleport when he is about to perfrom the attack. At this time you need to lock on to him and hit him with the strike raid ability. Once you interrupt him you won't get hit by it and he will use his flame pillar attack.

If you do get hit make sure you have second chance equipped so you can come back with one hp.

THXZ! that reallllllllly helped but now, hes too fast!!!

The only advice I have for that is to try and level up a bit. If you can get your hp higher and defense higher it will help out a ton. Keep working on the timing of his attacks. This boss fight is very tough and takes many tries.
