I don't need to say that I'm at FF8's final boss because this is all about it...

1st try: Lost on the third form. It was just to check how strong it was, of course!

2nd try: Lost on fourth and last form, because Rinoa died and vanished before I could revive her. She vanished really fast. 1 and half hours thrown away because of 3 seconds...

So here's my ultimate tactic for defeating the powerful Ultimecia that isn't so strong, after all:

1st form:

Obtain my desired party (because the fight starts with random characters.

Cast shell and triple on everyone.

Kick her ass.

2nd form:

Always keep shell on because of that incredibly strong "shockwave pulsar" and cast a very slow GF when "it" launches it and with that the GF takes all the damage.

Keep Haste on too.

Triple Holy and triple Meteor him.

Cast Aura on Squall and use Renzokuken Always I can.

Try to save Mega Elixirs (3 of them) and Heroes (6).

Use meltdown.

3rd form:

The same tactic used in the second form.

4th form:

Same tactic used in the previous two forms, plus this:

She launches Hell's Judgment in the beginning so I'll use a Mega Elixir after that but not before I use another Renzokuken.

Always keep healing myself, always!

When her Belly becomes vulnerable, immediately destroy it before she draws Apocalypse.

Start using Heroes

She's not that strong and if none of my characters vanishes I should beat her easily.

For those who beat her, any suggestions?
