TT mostly just sat there and used Magical Activation or defend. Y'shtola buffed and healed. Refia healed and used Panacea as well as Manufacted Nethicite (LIFESAVER). WoL switched between debuffs and The Light is With Us! Noctis used Cover as well as Point-Warp, and Fish every four turns (this is where I screwed the no items mission; he can't Point-Warp unless he already has MP - oops. Oh well, the reward is piddling anyway).
This setup was fairly balanced; I felt like I had just enough of defense/healing and maybe a bit more firepower than I needed. Ultima's 4mm HP is misleading; her defenses are pathetic and she went down fast. I recommend ignoring the "no items" mission and just using a provoke tank for Mute; it's not a big deal and if you REALLY care about Wind Resist+15% you can just come back and get it later. The end was a little clutch; I assumed Magical Activation + Chaos Wave would slaughter the demons and it left one of them with a sliver of HP but Noctis was able to take care of that.
Overall a fun battle. I like that you aren't able to just bum rush this and get all the rewards, and I felt good making it to the end without a single death.
