Guild Wars 2

Hello, I recently had a Holographic wings drop from a mob. And my question is, do i have to link it to a back item? If I find a better back item and change it, will the wings disappear? Are they bound to only one item? Thanks for answers!

They are bound to the item you put them on. If you get a better back piece later, and would like to transfer the look, you would use a Crystal to do it, if the source or destination piece is level 80, otherwise you’d use a Stone.

since he may not know what crystals and stones are:

Ah, it’s good to know that the transformed appearance of a skin can be moved the same as an “unmodified” appearance can be. Makes sense of course if you realise that the replacement skin is a replacement not an overlay, but that wasn’t immediately obvious to me. Thanks.
