Ultimate Yunalesca beaten using Mage Meta, no real curveballs other than Terra using Silencega as her 2nd move, and Lulu swapping from Blizzaja (Go To Aja thanks to Ice Staff) to Waterja for obvious reasons.
The only thing notable was that I had to learn some timing thanks to the 3rd Phase often starting when my Mitigation starts to drop, so just wanted to time a Heavy Regen RW/Soul Break to kick off right after Hellbiter, which should be enough time to stop ST Holies (MT Holies hit regardless) and get Mitigation up until the next Hellbiter. On the winning run, I realize IN HINDSIGHT "wait, why am I casting Sentinel Grimoire on turn 1? She's completely neutered by Silence!" Oh well.
Did the Cid Mission for BFA. Initially went with Tidus, Yuna, Auron, Lulu and Rikku thanks to Soul Breaks. Yuna runs Diaga, so Rikku covers Protectga with Envoloping Etude. I screw up the initial run since I just did a Favorite setting and forgot Lulu's using Trash Clearing moves, oops! In an attempt to redo it, I realize it's just easier to bring Braska, who can run Diaga for the Requirement, so I egg him up (and Rikku too for that matter, because why not get her to level 65? She was already 63 granted), equip him with Bahamut and Diaga, and...proceed to fail miserably beacuse Jecht Beam. Ok, I actually got very close with this set up (Divine Guardian RW if you're wondering), down to a pixel, and I would have taken a non-mastery win, as I would have just returned with an A Team of like Beatrix, Vaan and Ramza and ripped him apart but alas, Tidus was slow'd and couldn't get one last hit in.
So I realize I just need to stop Jecht Beam from hitting hard since losing Rikku halfway into the fight is ultimately what got me (seriously, if she acted one more time, I'd have won! Magic Pixels are a bitch), so I end up using the following set up in what is my winning run:
Tidus: R4 Magic Break, R4 Lifesiphon, A +20% Sword Damage RM (he has Slice and Dice Soul Break)
Yuna: R2 Protectga, R5 Curaja, Mako's Might (she has Hymn of the Fayth)
Auron: R3 Mirror of Equity, R3 Lifesiphon, a +20% Katana Damage RM (has Banishing Blade SSB)
Braska: R2 Shellga, R4 Diaga, Summoner's Prayer (he was equipped for Mind, as you'd expect, so Diaga was doing 9k+)
Rikku: R3 Dismissal, R2 Thief's Revenge, Dragoon's Determination (has Machina Sabotage SB)
RW: Divine Guardian
Magic Break covers one condition, Auron and Rikku Soul Breaks cover the other (also while neutering a lot of his damage in the 2nd half of the fight), Braska hits weakness, Yuna heals. In addition to this, Mirror of Equity used since I didn't have Shout (wanted to RW it but didn't show up), and made sure it's buff was up before a Banishing Blade went off. Rikku's spams Dismissals until her Soul Break gauge is in hopes it kicks in, after which she goes to Thief's Revenge because hey, now she has a boosted attack so why not maximize that damage? Braska Spams Diaga after casting Shellga and otherwise nothing else.
Winning run had Braska dying late in the fight, but ultimately didn't matter. 2 Medal loss, both on damage, so yeah, I'm good.
So what to do now? Murder Ark some more, of course!
