I'd say it would be Percent, but you probably want the answer Apocalypse. If you do not wish to view decapitated squirrels in the future, then do not reply to this message. If you do wish to view decapitated squirrels in forthcoming messages, you need to get out more. You're wrong, it's not 35,000 gil, and there is a magic called Percent, but not in the normal game. It is one of six of Selphie's special magic limits, but it was left out of the game.
Apocalypse is another, but that was left out as well, except for the final boss.
Apparently, you can get Percent by using GameShark. I don't know much about that, as I don't own a GameShark, but there are a lot of people around here who do. Try asking one of them.
