Anyone did a 122333 game?

[Shiva_]

I guess I got lucky getting firefly on my 4th try (But I was panicing because the zombies almost raped my entire party and I almost died on the 3rd last zone when the boms were chasing me). And even getting a second one after the LP farming when I returned to kill mateus.

You were pretty lucky. I must've have bad luck or something.
The chest has a 55% chance of being there.
Then there's a 55% chance that it's going to be an item and a 45% chance that there will be gil in it.
If it's an item, there's a 50% chance that it's a Knot of Rust and a 50% chance that it's the Firefly.

So your chance of getting the Firefly from that chest is around 15%

As far as fleeing, the best way I found to flee is:
1) Un-equip everybody's weapons/shields.
2) Turn OFF all gambits. Buff up if you want to.
3) Have only one person active at a time and use him to flee.
4) When that person gets KO'ed, switch in someone else to continue fleeing.
5) Whenever you enter a new zone, stay right in the same spot to full heal & revive, and then continue fleeing.

And yeah the leviathan judges were a pain. I remember using hi-potions on the imperial soldiers and even pushing the soldiers away from vossler so he wouldnt kill them ( he got nearest visible attack gambit I think D: ).

After failing a few times in that battle, I ended up re-loading my save file at Bhujerba (I had made another one for when I went on the Leviathan). I teleported to Rabanastre and did the Thextera hunt, and Montblanc gave me two Warp Motes for part of my reward. I then went back to the Leviathan. Before entering the fight this time, I KO'ed Vossler so he wouldn't mess with the other soldiers. At the first part of the fight, I used my Warp Motes to get rid of all the surrounding soldiers. Once the two Judges were left, I revived Vossler so he could help. Whenever you use Warp Motes or the Warp spell to get rid of foes, you won't gain any experience.

And for Mateus it helps a lot if you immobilize the ice azers

Immobilize kept missing half of the time for some reason.

In this battle, overall, having my guys put to "Sleep" and the Ice Azers' casting Curaga on Mateus were the biggest problems. Sleep was actually the worst because time was being wasted, and turns were being wasted as well to throw Alarm Clocks or wait until your guys get hit so they could get woken up. I ended up getting some Nishijin Belts and equipping them on two of my allies and having my third one equipped with the Dawn Shard so he could take 0 damage from the Ice Azers.

I also got a Nihopalaoa right before I tried him again. Using a remedy on him with it on was able to inflict him with Slow. I had done a total of 10 hunts before trying him again so it could become available.

Those Nishijin Belts and being able to put Mateus in Slow status using Nihopalaoa + Remedy, along with my guys being Haste'd, made the battle go more smoothly, and I was able to take him down ok. Swapping Ice Shields or a Shell Shield on my allies right before Blizzaja helped as well. Sap was never anything I had to worry about as everyone was giving out Hi-Potions as needed anyway.
