I definatly agree with her, even at high levels, Gained JP Up is a must have! Also, I know where you mayu be at, there are lots of male thieves, right? Ig I were you, I would recruit some men so they can't be charmed. Level up with them, perhaps make a priest with life, cure, protect, and shell at the very least, or a chemist. As I said, in that battle, you want men, because the male thieves will charm your females. I had all my females in my party charmed the first time I tired that fight, and was slain because of it.
