How do i get final attack materia? i know where i get it but should i take omnish lash and w-summon in a same visit at battle square to have that special battle?
Did it made any sense? 
Hrm, I think you just gotta get enough points or something. I dont remember. I never got it, I never needed it.
Yeah, you have to have both Omnislash and W-Summon on at the same time to get the special battle. Then you just win all eight rounds. Easy, right?
I remembered so but perhaps i went saveing game after i got omnishlash then came back and got w-summon maybe thats why i didnt got special battle.
