Finished the collab event, minus the 凶+ fight that looks like I want R2 Meteo for it (I am 3 MNeOs away. I can fuckin' taste it. It tastes like cellphone.)
The Normal 凶 event was not particularly hard. Two enemies weak to fire, so I brought out Gilgamesh with Flaming Weeaboo, Ramza with Power/Mag breaks, Zack with Dual Delay/Indoor Spell, mages on heal and buffgas. Contemplated making Firaga Strike but decided against it and it turned out I didn't need it.
凶+ looks like a rehash of the Bahamut SIN fight, only easier (or at the very least for me, doable). Adds that respawn, big damage move based on how many adds are left. Mostly easier because if you attack the adds and they don't die, they have a non-neglible chance of dealing 3k-6k to the big boy, so whittling them down with Ruinga and killing them with Meteo before the big attack goes off seems ideal. Honed Ruinga to R4 for it and will tackle it after Saturday when I'll very possibly have Meteo at R2.
I just now realized that Zack does not have Spellblade 5. Actually, nobody on my A team does, an issue which has not mattered before now. Celes is sadly only L50 so as nice as Tornado strike would be for this fight I'll have to pass. If I'm reaaaally still having trouble, I figured what I'd do is blow my Beginner banner freebie on Bartz' Air Knife (Wind elemental SB baby), pump him full of eggs and run him through the ringer Sunday and whatnot, and swap him for Zack. Bartz is on the levelling team anyway, now that I actually have him, thanks to his pretty little Dualcast Spellblade record materia. So pretty. Wanna get with that materia. Regardless, I'm pretty sure that's what I'm gonna finally use that banner for now. I like bartz well enough and Spellblade is a niche I apparently need filled with some hot blowhard action.
