JUMBO FLAN TOP TIPS: first cast hastega and shell on entire party. then cast reflect onto one of ur characters. then have one character use doublecast flare on the person u hav used reflect on (u can use ultima but the animation is just too long n it doesn't do much more damage than flare). then just repeatedly use copycat to kill his ass (i think u may be able to cast slow on jumbo flan but only if u hit a reflected character, i can't remember if he's immune tho its been a while!!!)
