can u say spamJebus i beat that game like a year ago, with all the ultimate weapons powered and everyone but Lulu and Kimahri did 99999 damage with each swing. I dont know how to beat the last Seymour (if thats who you mean) cause i had auron yuna and rikku doing 99999 by the time i got there and pwned his lame ass.
nope wrong boss so use this it worked for me and if you havebt got reflect just o.d like ya neva o.des b4if the santuary kepper is the one after you do that tetris cloyster of trials then the all overdrive didnt work for me(nearly did) so every 1 and evy aeons overdrive up ise em but dont 4get to cure when you need to + when you kill it go back outside and get vy 1s o.ds(i cant be bothered to say overdrive over and over again) so when you kill sactury kepper dont go down the lift go back out side get evy 1s o.d up cus there a boss strigh after(more thn 1)(more thn 2 even ) good luck
use this way itl workthat might work.... but i have a strategie of my own, i cast reflect on skeeper (dont like to use full name, blablabla, too lazy, blablabla) when he uses curaga on himself, i will be healed, and with yuna's and bahamuts oveerdrive(24.000 dmg) i can have 2 turns, if he DOESN'T use mana breath, and he's dead.
