final boss is relatively easy if you use this method
equip MATT with viking helmet, genji armor, and soul eater(fully maxed) he will avg. 30k damage/turn and have high defense
equip NATALIE with pope hat and dress and dark tooth staff (fully maxed) pope hat and dress has defense in general and boosts healing and dark tooth has powerful attack and boosts healing
equip LANCE with soldier helmet and camouflage and shadow blaster. helmet will randomly give medipacks plus has high defense. camouflage outfit randomly calls missiles and tank, also good defense. shadow blaster increases magic attack
MATT will be besekered pretty much the whole time, but will have super powerful attack
NATALIE will be healing the whole time, once in awhile a good attack/debuff. have her use kyun as limit break
LANCE will be hitting with any elemental attacks that akron/enemy is weak against. use nuke or oblivion limit break
if u are having trouble with final boss plz try this!!!!
