What is the easiest way to acquire the Dark Sandstorm outfit?

[animekitty]

I got it out of 9 chests that the boss drops every run

 

Oh and this isnt the bidding loot chest this is just the quest finished chest.

I would love this outfit, but I'm not sure if there's an easy way to farm it. Do you guys have any tips? Also how rare is it to drop?

It's pretty simple to just run the dungeon a few times in a pug since the outfit drops from the box at the end.

i personally farmed it at lvl 45 with one other lvl 45 and got mine out of the very first chest (ran it again to try to get it for my farmin buddy, no dice, he had to go after that)

 

it's easy to farm so long as you dont try solo, that bird's air phase is a royal pain solo because of the knockdown feathers.  mroe people is nice cause you'll down him faster and since it can drop by the chest, everyone can get a shot at it each run.
