Need URGENT help with Ultima Weapon….T_T Please?

Okay…so I gotten Bahamut….with Squall’s LionHeart combo and I gotten him…
then my goal is to get Eden and beat crap on Ultima Weapon.

Problem is…

Exactly, how to beat him?
I referred to so many walkthrough and 99% of them say to just cast Aura non-stop…some say to cast Aura – Invincible Moon – Aura – Triple, some say to cast Invincible Moon, summon Cerberus or cast Triple, Aura, Protect, Shell on everybody…some say Mighty Guard – Aura

So I my party order is…
Rinoa (lvl 7+), Quistis (lvl 100), Squall (lvl 100)

Rinoa: LV down, GF, Attack, Kamikaze
GF: Cactuar, Tonberry, Ifrit, Carbuncle

Quistis: GF, Item, Attack, Recover
GF: Leviathan, Shiva, Quezacotl, Pandemona

Squall: Mug, Magic, GF, Draw
P/S: With the most magic amounts then the others
GF: Diablos, Bahamut, Doomtrain, Cerberus, Alexander

So….I am so lost when it comes to fight Ultima Weapon because when the start of the battle, I forgot to cast Meltdown on him, then just cast Aura on everybody, Quistis use Mighty Guard while waiting for Squall’s Limit Break then suddenly – Ultima Weapon: 2 sec – Meteor – 2 sec – Sword Swipe – 2 sec Gravija – 2 sec – Meteor – When Quistis is the only one standing – Light Pillar

…..T_T help please? *cookies for everyone*

Haven’t fought him yet, but I’d suggest Aura on Squall and Lion Heart madness…

train the crap out of Rinoa, for real you’ll waste a lot of time healing her.

lol okay x.x thanks guys. I just defeated Ultima Weapon but ermmm…wasted 1 Hero >_>" I used Hero on Squall and Squall did Lion heart madness, then Rinoa’s Angelo Strike did the rest and >_> Ultima Weapon defeated….*sweat-drops*

Do things the lol’in way. STR at 255 plus Kamikaze = 50k damage. Have VIT at 255 on one of the remaining two characters and equip them with recover and revive. Plough the shit out of your foe with a combination of meltdown plus Zell’s limit with his STR at 255. Easy peasy.
