Guild Wars 2

Hello, I have a question about skins. Does it only replace one of my armor pieces then it’s gone and I cant use it again? Or does it replace them every time I get an armor and it defaults to the skin? Please help.

When you get a skin, you can use it once to replace the looks of your armor.
If you get a new piece of armor and want the skin on that armor aswell, you can do so by going to the wardrobe. This will cost you 1 transmutation charge.

It’ll replace the appearance of the one piece of armor you use it on. Then, afterward, that skin will be part of your wardrobe. You can spend a Transmutation Charge to reskin something else.

For example:
Let’s say I have a set of Knight armor and a set of Berzerker armor. I buy a Rampart Skin on the Gem Store and I want to use it on both.
I can reskin all my Knight armor bits for free. Now they will all look like Rampart armor. This unlocks the skins in my Wardrobe (account-wide).
Later I want my Berzerker gloves and boots to look like Rampart armor, too. I can use the Wardrobe tab to skin them. It costs 2 Transmutation Charges in this case.
