Guild Wars 2

I just bought Crustacea to add it to Exotic Collection. But when I checked it description I see only:
“Skin Locked
Crustacea”
Why I don’t see “Collectible”, it is a bug? When I soulbound or destroy it, will it be added to my Exotic Collection?

You have to account bind or destroy an item before it can be added to a collection. So, either equip it on a character, right click and choose “Unlock skin”, or salvage it.

I wasn’t sure, but I checked dungeon’s weapons and they also don’t have ‘Collectible’ status. So I unlocked the skin and it worked.
