Guild Wars 2

Hi, i bought this great sword i really like (in terms of how it looks) and i want all my swords to look that way but apparently i need a transmutation charge.

Does one transmutation charge work only for one weapon or do i get to reuse the skin over and over again?

and if not re-usable then where can i get these charges? THANK YOU

One transmute charge is only good for one transmutation. If you wish to transmute the skin again on other weapons/armor you will need more charges. Charges can be acquired either through the gem store or for fee by completing maps, sometimes from login rewards, and through PvP reward tracks.

1 Charge = 1 Change.
If say you are using an Axe and you have a skin in the wardrobe you wish to use on both your offhand and main hand, it will require 2 charges.

Completing each of the 6 CITY MAPS is easy. Once you get the hang of it, you can zap through Rata Sum in 15-20 minutes for a Transmutation Charge. I have an extra character slot reserved just for that.
