special item? wth? never heard of that, well thks anyway. Can you tell me what Cid's special weapon is and Yuffies?

So Nanaki's weapon is just like Cid's? or is Cid's different? bc out of all the time he had 999 MP, he did 9999 dmg.

and another question for a stradegy, I hate tifa's limit, I'd rather her just attack, will setting her limit break all the way up and then let her use mug make her do 9999 dmg?(since the attack bar goes away with limit breaks)

edit: can't I always just put curse on her when she gets limit break? will that work?
