You also need Aura magic/stones and Holy wars

Step one, first use Aura on Squall
Step Two, use holy war.
Step Three, Draw Eden
Step four, On squall next turn use his limit break and try and get a perfect
Step five, repeat squall's limit until Ultima weapon is a pile of fudge on the floor
What!? Use Holy wars on Ultima weapon????? What a waste! Holy wars are hard to get if you don't want to waste your precious Gilgamesh card. You can defeat Ultima weapon with everyones first weapons, no hero items and low level characters. If you are at low level, then he is as well. Equip quake at elem def. I myself prefere to get Eden from Timat in Ultimecias castle.
