I didn't get any good pictures, but Ultima got nasty at this bit. Halfway through the fight he starts launching Magitek Bits that shoot out lasers that hurt, and there a bunch of them crisscrossing the entire battlefield, and it's possible more than 1 will have you in their paths.
Also towards the end Lahabrea forced Gaius to charge up another Ultima, but fortunately we killed it before it could fire it.
Gaius dies
The Ultima Weapon is destroyed (in a hilariously pathetically small Ultima)
But Lahabrea remains.
He's basically just a punching bag that taunts us that if we kill him, so will this body. Hydaelin says it's ok though and to just ignore Lahabrea. If you say so disembodied voice boss... and then things got trippy
So that happened. I guess Thancred is no longer possessed or something?
Maggie to the rescue! Good Bot. Best Friend.
It's totally Chaos.
THE END
OR IS IT?
Bonus:
This dungeon's gimmick is that thing below the title. It's a dangerous Mold Colony that triggers Hecteyes into appearing from smalle colonies. Also some poisonous tile that disappear when you kill the flies
This guy is like Parasite Cage from KH. He can swallow somebody, and we have to destroy the Maw to release them.
This one was weird. Basically Arioch refuses to land and fight unless we kill enough of his prey enemies to entice him to stay and fight us. I don' know why we don't just ignore it, but okay.
Huh. I was not expecting Diabolos here. His gimmick is still DARKNESS and gravity, and he also has a NIghtmare attack that puts the entire party to sleep. When there are too many Gravity Orbs near him, he needs to be moved out of them because those times combined hurt. Also, we need to dodge his Ultimate by opening two Voidgates with the same pattern, which suck us in and make us intangible to Diabolos's attacks.
Bonus again:
