To get to Omega Weapon first leave the party your gonna use
for the battle at the switch point by the fountain. Using your secondary party, go through the door on the right side at the
top of the steps of the Front Foyer. This should take you to a room with a bell and a rope at the bottom of the stairs. Pull
this rope to start the timer and leave your secondary party at the switch point in the same room. Take control of your main
party and run through the large door to the north of the fountain. In the next room you'll find Omega Weapon waiting for you
in the same place as the black smoke used to be. Run into him to engage the battle.
To prepare for this battle you'll need to rejunction your spells,
make sure you have your best weapons and refine the cards you have into valuable items.
First, use Card Mod to refine all of the rare cards you've been
collecting. Hopefully you've bothered to get the Gilgamesh, Bahamut, Angelo, Laguna and Chubby Chocobo Cards. If not, then
you'd better hope this is your lucky day.
Squall, Irvine and Zell should have there ultimate weapons.
This is crucial because without his Lion Heart weapon Squall can't use his Lion Heart limit break which is the most powerful
attack in the game and causes about 200,000 damage without accounting for the damage caused by Renzokuken.
Junction 100 Death spells to each of your characters status
defense. If you don't have enough Death spells then refine more from Saw Blades, Dead Spirits and Chef's Knifes. This is extremely
important, because Omega Weapon uses Level 5 Death which will kill everyone with a single blow. Junction 100 ultima spells
to the strenght of the male characters or Rinoa and 100 ultima spells to the magic of Quistis or Selphie. Junction 100 triple
spells to everyones speed. Junction 100 reflect spells to everyones spirit. Junction 100 curaga spells to everyones vitality.
Junction 100 full-life spells to everyones HP. Junction 100 meteor or 100 tornado spells to everyones evasion. Don't junction
any magic spells to anyones elemental attack.
Make sure everyone can use magic and items. Make sure you've
equiped a character with revive and another one with recover. Make sure you have some aura magic or some aura stones. Make
sure you have a few Holy Wars or Heros.
Unequip everyones character abilities and equip these. Give
Squall, Irvine, Zell and Rinoa strenght plus 60%. Give Quistis and Selphie magic plus 60%. Give everyone spirit plus 60% and
vitality plus 60%. If you have any spaces left over equip things like speed plus 40%, return damage, auto-haste, auto-protect
or auto-shell. If you have Carbuncle on a character who is very strong then equip that character with counter.
If your Eden compatability is under 700 then don't even bother
with using it. Don't use any other GFs for this battle either.
For this battle my favorite party is Squall, Irvine and Quistis.
Here is the equiping that I gave them.
