Supernova eh? I remember getting hit with it... I also lold at how over the top it was with the planents being destroyed and all... but I forgot the damage done.

Omnislash can be acquired in the battle arena in the Gold Saucer.

well I finished it last night

& guess what

just started FFX!! lol

how many battles do you have to win to get omnislash?

FFX? you're gonna love it.

@Xen

Its my 4th playthrough

yeah already loving it!

I still don't believe grfx are that good in a 8 year old game!

4th? hehe... same as me.

I havnet finished FF X but at the time I was playing it I didnt enjoy it nearly as much as FF VII.

@Xen

How many battles do you need to go through in the battle arena to get omnislash?

Earn 64000 battle points.. yep.. you heard me.. :P

so that means like over 100 battles lolz without saving or leaving..

100? it took me 9... I think...

Try to get some huge handicaps toward the end... disabled materias in the last stages help a lot.
