naww , get juna's , auron's and ricku's celestial weapon , next get dark matters and give the others all a break damage limit on a weapon, .. sure your strength is above 150 , and you almost always give 99,999 damage with all , no need for all celestial weapons, besides wakka, rikku and tidus give less damage when HP is low , better make them a break dmg limit weapon. so if hp is low you still do max damage
except for nemesis and that anoying iron dude where you get hp sphere's from.. i give on all max dmg
