Guild Wars 2

Is it possible to obtain any of the character creation skins, the helm and the pauldrons, if you’ve gotten rid of the items?

there a tuto in youtube, how to get the started armors using transmutation stone, making a new character. xmuting the part you want whit one BOU item and trnafering to the bank.

If you have a free character slot, you can still get additional items.

Simply make another guardian and choose the item you want. Then find/buy a white or blue quality Heavy armor piece and have your second guardian transmute the goggles onto that headpiece with a basic transmutation stone.

The item should now change from Soulbound to Account Bound, so you can store them in your bank and have your other guardian pick them up!
