in the game, the image shows the ancient shrouded hood having a mask over the mouth and nose, but it doesnt show up? and the armor seems like it has the sword holster on the back and that isnt there either, is this intended or was this just an oversight? will i see this fixed? i was really looking forward to getting this for the sake of it being different than the regular shrouded armor

I think its a bug, not intentional. Once you pick them up, at least in my game, they just acted like regular shrouded equipment and stacked with the ones I already had. I assume they are supposed to be different, but eh, it'll probably get fixed sooner or later. Hopefully sooner.
