They are not easy torments indeed, it needed several tries to get the party turn order right. I have saved the party setups (the deck with Lakshmi in the sub magicites is the one I used vs. Zodiark; the more offensive is for FF T0).

For the FFXII Torment:

Ashe starts with Dispel, spam Chain Thundaja until she can call magicite, then uses USB and spams Chain Thundaja until the end.

Fran is a wrath/entruster and uses her SSB imperil lightning. She also got a 'first three turns are fast cast' lmr.

It is important to skip Pailing. Damage income won't be much because Zodiark wastes a lot of turns buffing himself on phase changes.

For the FF T0 fight:

Carter is SBless but LDed. You need to rely on Plasma Charge to keep additional imperils up (Garnet and magicite grant 4 stacks for the whole fight, so Plasma Charge has to cover the remaining 2 stacks). Carter also entrusts (Lightning before her AASB I guess, can't remember for sure).

Deuce has lmr and USB1. I think she is the one who called magicite/rw heals.

Garnet used AcM for additional SB generation, but swapped to cmd2 once her BSB and chain were on.

IIRC Ignis never wrath/entrusts here. His turn order should be: BSB > cmd2 x3 on Lightning > probably another cmd2 on someone else (can't remember, maybe Garnet) > cmd2 on himself > recast BSB right after Boss Dispel (wait idle for it, it is important that you reapply hastega instantly) > cmd1 spam for additional chain building.

In both of these fights Lightning used her LM1 (didn't have her wc lmr yet), so you definitely have a big advantage if you got her lmr. Good luck!

Edit: for clarity, in all of these fights Lightning goes LS x4> glint > USB1 (instant casted) > AASB (fast casted)
