Okay, so, Edea event bonus battles, all done while I was perceptively drunk last night. Here's my setup for the Three Stoges:
Rinoa (L80): R5 Maduin, R4 Blizzaja
Bartz (L80): R5 Aerora Strike, R4 Lifesiphon
Edea (L71): R4 Bioga, R3 Meteor
Yuna (L80): R2 Protectga, R5 Curaja
Quistis (L65): R4 Thundaja, R4 Magic Breakdown
RW: Sentinel's Grimoire
So yeah, mostly mage meta since I wanted to build mastery on both Rinoa's and Edea's SBs and my mage synergy in FF8 is downright insane. No S/Ls, though I didn't really use the AoE damage much. Quistis and Edea are kinda redundant (both run Hastega SBs), but I wanted to field both Protectga and Shellga. Regardless, Inaugural Parade is very legit, the girls were ramming caps without hitting weakness (though the synergy obviously helps). I honestly didn't notice their offense either, but the fight ended pretty fast. Kinda disappointing after how nasty they were in Rinoa's reissue.
Ultima Weapon... oof. I know part of it was me being blazingly drunk, but it took me at least four S/Ls to get into the fight's rhythm, which is bizarre given how unsophisticated the fight is. Ultima's just a DPS check, but the offense is scary as fuck and you don't want to spend even a second outside the scope of a SG/SSII cast. One of my failed runs involved eating a 3.5k damage Meteor (under Shellga and Magic Breakdown) that blew up half my party. First attempt involved Edea, Ramza, Bartz, Gilgamesh and Yuna, but I had to replace Edea with Lightning even though she was dropping 8k damage Waterjas sans buffs. Winning setup looked like this:
Lightning (L80): R4 Lifesiphon, R4 Dismissal
Bartz (L80): R4 Lifesiphon, R4 Pound
Gilgamesh (L80): R4 Banishing Strike, R2 Saint Cross
Yuna (L80): R5 Curaja, R2 Shellga
Ramza (L80): R4 Magic Breakdown, R3 Full Break
RW: Sentinel's Grimoire
Pretty milquetoaste, but that's how those fights go, really. You're running against the clock here and he hits too hard for anything else to be effective.
