After a lot of struggling against Rufus and Hojo, these XII Ultimates were extremely cathartic. I did both of them on my first attempts.
I had underestimated the physical damage from this one, as I didn't realize there would be 3 adds. As a result, Yuffie died mid-battle. I'm not even sure I ever used her SB. If I had to do it over, I'd of brought Agrias w/ Protectga and Lifesiphion vs Yuffie. Alas, once I took down the other Judges I still mastered it with no other issues. Celes's SSB was a lifesaver (I have a feeling I'll say this a lot going forward). She sucked up nearly all of his weak phase damage and just kept pelting him with Flare Strikes.
This was a really fun battle. At first I was taking big physical hits and thought I was doomed because I had already used Protectga, FB and PBD. Then I realized that the hits were not coming from Cid but from the 2 adds. I struck them both with PBD and then went back to ignoring them. The rest of the fight was a cakewalk.
U/U+ Mastered on the first try each. P. Cecil's SSB is glorious.
It is wonderful, especially when we have Holy Vuln bosses where we get 29,997 damage per cast. I'll often find myself in battles where Celes and/or Locke do ~25k or so per SSB cast, while Pecil does near his max.
