Lost Barong In Dyna Buburimu

So I'd really like to get the Tjukurrpa Axe for my BST until I finish trials (and am kinda short on gil), but haven't had much luck with the dragons in Buburimu.

Can anyone give me a clue on how to kill Lost Barong? I haven't been able to find any testimonials on the battle, not even a hint.

What's a possible party setup? Is it possible to duo him? I have 99 BST/SMN/DNC/BLU/BLM/WAR/MNK/DRG/PLD and my fiance has WHM/DRG/THF at 99. Earlier I tried a similar dragon on BST with WHM and my first and second FaithfulFalcors died quickly, as did we.

Could anyone give me some information on how to kill Lost Barong? Or, if you're on Odin, I'd really appreciate if you could give me a hand with getting my axe. ^^;

Thankies!
