Well, two U++ fight setups to post about. Not much to say about Ultimate and Ultimate+ other than "yeah, Quistis melted them away".
U++ Sorceresses - A Team
L80 Quistis (Wrath R4/Ruinga R4, Battleforged)
L80 Braska (Shiva R5/Valefor R5, Dr. Mog's Teachings)
L80 Onion Knight (Meteor R3/Chain Blizzaga R3, Mako Might)
L80 Vanille (Curaja R5/Shellga R2, Master In White)
L80 Cait Sith (Heathen Frolic Sarabande R4/Multibreak R3, Ace Striker)
RW: hinode's Stoneskin II
Everything I need covered in a neat little package. With Hail to the Queen, Quistis' potential offense turns simply -nuts-: That's basically 2.63x MAG buffing after all my stackables are in place. That goes -well- over the MAG softcap, but fine, all fine, especially with Enpoison to boost Cloying Fragrance. She was responsible for about 70% of my damage in that fight in spite of only hitting weakness at one part of the battle. The fight really can get hectic without strong mitigation, though: lots of targets and that magic focus can make things quite unfun. The standard measures work just fine, though.
U++ Sorceresses - Tier Challenge Setup
L80 Quistis (Wrath R4/Ruinga R4, Dr. Mog's Teachings)
L80 Palom (Meteor R3/Chain Blizzaga R3, Light of Hope)
L80 Porom (Curaja R4/Shellga R2, Master In White)
L80 Edward (Magic Breakdown R4/Full Break R3, Mako Might)
RW: Stoneskin II
Similar deal, only less elegant and even more Quistis-focused. The strong mitigation becomes -more- needed with less party members as well, and it's hard to keep enemies debuffed when you have to target them individually. Worth noting, however, that Quistis' BSB entry hit the final phase for 44k with Song of Swiftness, Enpoison and Vile Ichor's buff up. En-element mage bursts are so gloriously dumb.
