Guild Wars 2

I bought a few level 40 swords from the Trading house and I’m unable to salvage them. I have plenty of inventory space and I tried with two different kinds of salvage kits (crude and basic).

Sounds like an item from one of the NPC weaponsmiths that you can find all over the game.

The only way to tell these apart is the internal id. The non salvagable ones should be renamed.
