since in FF8, you had the opportunity to use all of your people, i had to make some last minute adjustments and discoveries and after battling ultimecia a few times (and losing) and figuring out what i was up against, i came up with the perfect formula...
Selphie: was my weakest so i gave her nothing... except cactuar and then i made her use kamikaze HAHA!
Irvine: I used the ammo mod to get as much pulse ammo as humanly possible cuz it took off 9,999
Quistis: she has mighty gaurd...
Rinoa: i used her dog nonstop in hope it would make me invincible
Zell: i figured out the exact pattern to get to my final heaven... that was good
Squall: My strongest character... i had him at 9,999 hp and he had the lionheart. everyone else i basically used to keep him in good shape!
