Since I don't want to create a new topic for a minor question, i'll ask it in here.
I read about the Special Battle in the GoldSaucer after you gain omnislash and w-summon... it should be unlocked, but i have ALL items from the battle arena, but no special battle for so far.

NOTE: i am going with Bugenhagen to the ancient city now (after the underwater huge materia).

Maybe I have to be further in the game in order to unlock thefinal battle....I can't remember anymore, so i was hoping that someone could help me out.

I really need the final attack materia and 3 ribbons (which creatures should I morph in the special battle for the ribbon?)
