Ultima Weapon not so….Ultima.

[Ultima Shadow]

PS: Ultima Weapon at Lv9~12 WAS a sucker. XD I kept on Drawing Ultima form him, oly using Phoenix Downs/Revive when Light Pillar. His other attacks couldn't kill me anyway.

I was absorbing Quake. Even if I wasn't, It would deal 200 damage.
Gravija can't kill you, obviously.
His sword slash dealt 200 damage.
And... without Shell... his Meteor dealt 82 DAMAGE PER METEOR LOL XD

I'm not suprised... since:

Ultima Weapon's stats varies a lot depending on his level, much more than most other bosses and enemies.
