Nathrian Weaponmasters functioning incorrectly

Hello everyone, We are currently aware of an issue that the Fated Weapon Tokens from the weekly dungeon quest are not allowing players to trade for a weapon. While this has already been fixed in game, the fix was not retroactive for those that already received them. In this case, please reach out to our Support Team for assistance, as they will be able to verify if you have a bugged item and trade it for a valid one.

tl;dr is that if you contact support they will exchange the faulty item for one that works. Until your ticket is dealt with there isn’t another remedy I’m afraid.
