Pm sent, what strategy do you recommend? I tried physical, mage, and a combo of both.
Request sent.
If you have the same units as Crimson Squall, then you should do:
Bartz (ifrit)
CoD (diablos)
Lenna (Shiva)
Charlotte (Golem)
Lightning (my lightning)
The sixth unit i recommend strongly that would be a Cecil or a unit that you can equip barfira, baraerora and barthundara.
That said, you should do the following:
Round 1: Phoenix down, dead.
Round 2: Cheer , barfira, shellga, barrage x2 (bartz and CoD), Ice blitz. The enemy will transform then and you should resist the attack. Then curaja with lenna. Potions of you need with charlotte, and repite barrage and ice blitz.
Round 3: Cheer, healing with the unit with the elemental resistance spells, imperil with charlotte, Barrage x2, ice blitz. The enemy then should buff its defense a lot. Curaja with lenna, dispel with any other member, barrage and ice blitz.
Round 4: The same thing in round 2, but use baraerora, and electric blitz with lightning.
Before golbez, restock energy and MP.
Golbez: Cheer, Barfira or Barthundara (thats a gamble because golbez should shoot fira or thundara here), imperil with charlotte (you can do shellga if you want to be more cautious) , barrage x2 and crushing blow with lightning.
Golbez then depending of the damage done, can do massive death (50% HP, and it has 50% chance) or massive paralysis (30% HP, and 70% chance). So its crucial that lenna HAS JEWELLED RING EQUIPPED. So curaja or esuna your party members, so imperil with charlotte if you didnt do it first turn, and barrage and crushing blow again.
You can do it, you only need patience.
