I'm struggling quite a bit with Ultima Weapon, any tips please? I can get to his weak phase fairly reliably, but get overwhelmed by the AoE. I don't have any OSB/BSB, but a fair few SSB.
Resource wise, i have all the standard 4* abilities pretty well honed. For 5* abilities, i have a couple at R3 (Flare, Holy, Thief's Revenge) and a few at R2 (Full Break, Dark Zone, Saint Cross, Gaia Cross, Meteor, Bahamut). As for characters, i have the following at LV 70+ (soul breaks in parenthesis where relevant):
Lv. 80 P. Cecil
Lv. 80 Bartz (SSB Excalibur)
Lv. 80 Faris (SSB Imperil Wind)
Lv. 80 Terra (Minerva)
Lv. 80 Celes (Runic)
Lv. 80 Cloud (Braver)
Lv. 80 Squall (Fated Circle)
Lv. 80 Lightning (SSB Crushing Blow)
Lv. 80 Ramza (SSB Shout)
Lv. 79 ExDeath (SSB Power of the Void, SSB Neo Almagest, Grand Cross)
Lv. 77 Red XIII (SSB Magic Comb)
Lv. 77 Rinoa
Lv. 75 Firion
Lv. 75 Lenna (Royal Devotion)
Lv. 74 Luneth (Advance)
Lv. 74 Locke (SSB Valiant Strike + +)
Lv. 74 Yuna (SSB Dragons Roar)
Lv. 74 Y'Shtola (Thyrus SS2)
Lv. 73 Krile
Lv. 72 Gilgamesh
Lv. 71 Ingus
Lv. 71 Tidus
Lv. 70 Selphie (SSB Dreamstage)
Lv. 70 Beatrix
Lv. 70 Auron
Lv. 70 Penelo (SSB Intercession)
So far i've typically been trying something like:
1. Knight
2. Support
3. ExDeath (Holy+Diaga spam, with Neo Almagest for Magic Blink)
4. White Mage
5. Flex, not really sure who would work best.
First 2/3 of the fight is no problem, but run out of steam just as things get super tough! Any suggestions much appreciated! I also have 50 mythril if any of the existing banners might make the difference, though that is all down to chance of course
