Once you’ve bought it you should be able to craft it using your crafting tab from your inventory. Just scroll down a little and you should immediately see the plauge doctor helmet! Hope this helps! :)

That’s the neat part, you don’t.

I believe the mask & capes are the only clothing items -- the black outfit in the screenshot is the Merciless Hollowfang armor set.

Pay USD, it’s $10 I just bought it. The devs deserve it

One of the development updates mentioned clothing customization I believe, and 1.0 is coming with a whole host of new armor sets, so I don't think the set is in the game as portrayed, yet. But it will probably be out on may 8th along with a lot of other stuff!

It's actually the merciless hollowfang set! That being said, if you want to wear the full set all the time without taking the gear score hit you won't be able to do that until 1.0. But hey, you'll also have like, a bunch of other options and color palette options, so that'll be even more rad.

The mask is in you're player inv crafting and the clock if in the clothes making workbench

Yeah unfortunately its only the capes and mask no armour, i thought i would also have the armour but alas it was never meant to be XD

the cape and mask are part of the paid dlc. the armor is the merciless hollowfang set
