Guild Wars 2

Hello guys i was wondering about the krytan armor skin can i wear it immediately on my items or should i use a transmutation crystal and if i used it on my item and i got a new item and wanted to use the set on can i take it off normally or should i buy some kind of an item and is the set permanent or does it stay for a while then disappears .

It’s an armor skin so you use it, the first time, like a transmutation crystal. You click on it and a panel appears. It’s permanent after that. If you get newer gear with different stats then you have to use a transmutation crystal to keep the look.
