Ironically, this was the first GO I successfully AAB... I was out of town, so I didn't get a chance to manual it until just now. I made a few observations that I think will be helpful to those struggling:

  • The trigger has higher priority than raging OD, so as long as you deal enough dmg every turn to get to the next trigger threshold, that pumpkin bomb won't go off
  • When I have VoF up on my light team, most of the debuffs don't land (I also use Barong as my main eidolon though)
  • However, burst reduction seems to still land (or maybe I was just unlucky), so don't count on bursting after the first FB even if you stack resistances


A few tactical suggestions based on those observations (FYI my non-light teams absolutely suck, so I haven't tested these with non-light):

  • Use spike dmg build, not fast build - bring the team that gives you the highest burst number, not your fastest team; the fire suggestion from unregistered is not a bad one
  • If that's not an option, bring buffs and debuffs with long duration instead of short CD
  • If you don't have those either, bring as much heal, def up, barrier, dmg cut and resistances as possible and time your abilities so that you eat OD when your kaisers/def up/barrier/whatever are up, then push Jack to trigger when defenses are down (if you have DATA buffs, hold them and stack them when you're pushing for the next trigger)
  • Bring BP and orb eat, so you make sure the OD occurs at the same time as the trigger to make her skip the OD completely - you still need decent dmg to pull it off

Get ready to toggle healing between Joan/Andromeda and Sol and use large potions as needed to keep your team alive.
That is my experience, too. I actually forgot I had potions, wouldn't have lost my SR if I used it, but only needed 5 himes alive, so, didn't matter.

If you activate Dark damage cuts as they're ready (because she's random you have to) you'll find yourself occasionally not eating 5k in one turn (maybe 3k or 2k) which means you can wait for healing to cycle back.
I don't think it's random, the triggers are dependent on hp (BIG thank you to Cobblemaniac for this btw): First action during start of battle, and below 90%, 70%, 50%, 30% and 15% HP. If Jack didn't hit one of those thresholds, she'll unleash the OD, at least that's what I observed, unless I just got really lucky?

The way I would put it is, 'cos you can't FB, you have to take it slow. So, the question is whether you take it slow with turtle strategy or some other non-burst offensive strategy.

Doesn't Jack cleanse your buffs during normal OD? I actually think that's worst than the random effects. Unless you manage your dmg very well, such that she skips her OD 'cos of the trigger. I actually did FB on T1 and pushed Jack into rage on T2 on my non-AAB run, so I didn't see the normal OD to confirm (for reference, my team was Andromeda (Ex VoF - should have done Ambush instead) Tish, Mike AW, Sol AW, Sati (SR), subs were Attar (SR) and Luchtaine (R)) Also, getting a regular burst, even if not FB is not that easy unless you have a lot of DATA buffs and ideally have someone like Mike that just gives BG. I agree that not saving for FB is a good idea though, it's risky to wait if someone can burst.

I will try to experiment more tmr and report back if I noticed anything interesting. If someone has an idea that they are dying to test, let me know (I'm done with all the missions except beat battle X 3 times and participate Y times, so I can afford to take more risks.)
