Well, I run around and train quite often. I recently aquired the LImit Glove abuility, which only works whn your HP is 1. To use it, you just let quina die, and use a phoenix down. She then has 1 hp, and does 9999 with limit glove! You can also use a high level quina to perform the pumpkin head, which does the difference between your max hp and current hp. Do you guys know any other useful quina moves?
