Note: This is not a challenge fight, it is a display fight, which is why I purposly toned down my junctions with weak magic. Quistis is LV100, Rinoa is LV61, and Squall is LV7.
The final boss of Disc 3 is Seifer. Adel isn't the final boss of Disc 3, just in case there's some confusion. Anyway, the second you enage in this fight, you hit a point of no return where you can't leave Lunatic Pandora and are forced to go onto the final disc after defeating Seifer. So make sure you did all side quests before hand, as cities are blocked off on disc 4 (they tried to storyline relate it for the reason they're blocked off, but it's most likely because of lack of disc space).
Anyway, this is a unique battle. Depending on if you did a certain sidequest earlier will depend on how this fight unfolds. Don't read beyond this sentence if you don't want to be spoiled on the fight. If you got Odin, a random appearing Guardian Force, then he will show up at the beginning of this fight and attempt to kill Seifer. Seifer sees him coming, and cuts him down. Then after Odin dies, his sword goes flying into the sky and a mysterious hand grabs it. If you did not get Odin, then the battle just starts like any other fight.
The other difference is if the Odin scenario happened, Seifer has a slim chance of doing his final Limit Break, Bloodfest. This is because Gilgamesh will eventually pop out, either if you hit Seifer too much, or if you take too long. Either way you're not really in control of it. If you're doing a no level game, I might suggest not getting Odin, as he randomly appears and kills enemies, which will get you exp. Gilgamesh is even worse, as he replaces Odin.
About the fight though, I wanted to test the theory if casting Aura on Seifer would make him do his Limit Break, like it does for Squall and company. Seems it doesn't. There's a slim chance he'll still do his Limit Break, but most likely not. I also KOed Rinoa, because her stupid dog ran into Seifer and is probably what caused Gilgamesh to show up so fast. But doesn't matter, I recorded him doing the Limit Break on a different slot where I didn't get Odin. But the fight was basically me stalling and hoping he'd do it without that. Also, you actually see Fujin talk normally before the fight.
Beating Seifer ends disc 3 after a little scene. Disc 4 is the final disc, and I do intend to record the Adel fight, as well as the final boss and Ultima Weapon and Omega Weapon. Then I'll most likely be done with FFVIII.
