Yeah, I wish hitting optimize didn't refill your SBs with junk, I always forget to clear them out afterwards and it's really annoying and adds to my input delay in the best case.
Anyway, Omega was a joke. It took me several tries just planning out the exact right loadout, but once I got that figured out the actual battle itself was a matter of rolling dice and hoping that 1) Bartz, Zack, and Tyro evaded blind, 2) Relm went before Reflect, and 3) Stop never missed twice in a row. I did craft Ixion to R5 as a precaution because I am sitting on literally THOUSANDS of orbs at this point due to diligent farming, but that ended up being probably unnecessary. In any case, I had like 2+1 Waifus in the battle, and that's always a plus. Anyway, the loadout:
Tina (R5 Thundaja, R5 Ixion), Devotion, MAG 518
Zacks (R1 Full Charge, R5 Thundara Strike), Sword Damage 1.2x, Silver Spectacles, ATK 532
Butts (R5 Indoor Spell, R5 Thundaga Strike), Dagger Damage 1.2x, Cloud's Goggles, ATK 539
Shitbrat (R3 Dispel, R3 Full Break), Dr. Mog's, Goddess Pendant, ATK 413
Rirumu (R3 Face, R5 Stop), Mag down Mind Up RM, Mind 512
Ramza Shout RW
Dispel was to help mitigate dice rolling in case Relm went after Omega put reflect up. Everyone has synergy here, so equips only matter in that you have good 5* equips and something to block blind for your spellblades. Terra was dealing 9500 x2 with Ixion after Faith, and 9999x flat with Thundaja regardless. Bartz and Zack hit around 9000 or so each after shout, and a little bit more after Fullbreak and Tyro's BSSB Defense Debuff.
Relm was MVP by far, and this battle marks the first time I've used stop on a high MND character instead of on some BM schmuck to hit mastery requirements. Turns out with 512 x 1.2 = 614 Mind Stop lasts at least two turns hasted (never had to find out if it was more), which gave me a free turn to Faith up Terra to boost her Ixion damage after the initial stop. Having stop proc before Reflect is ideal mostly because that reflect is scripted, and if you do miss two stops in a row (or the stop right after faith), then all I had to do was dispel with Tyro and move on.
Ixion at R3 or R4 would probably have sufficed, honestly. I had 2-3 charges of my Thundara/ga strikes left and almost a full charge on both Zack and Bartz's SBs which would have made up for the loss of 10-20k damage for not having those hones. Oh well, its not like I was saving those orbs for anything. Chain Thundaga when it comes? Frankly thanks to Ix that's not as much of a priority as Chain Blizzaga or Chain Firaga, and I already decided I don't really need FB past R3.
Anyway, glad to have these fights done so I can move on. In levelling news, Bartz broke 90 and Cloud is at 85, I may just use eggs on him to harvest his organ. U+ Kraken also netted me another MC3, so I'm thinking I may use that on Terra or Ramza soon. The FF2 event will probably provide me with another one anyway so I may as well do both.
