Guild Wars 2

I’m trying to transmute my Valkyrie Exalted Mask to look like my new Furnace Reward Light helm. I pull up the transmutation panel using a Fine Transmutation Stone, put each piece in their respective slot, and click the stats I want (Valkyrie stats from my crafted helm and the rune from the dungeon helm).

For some reason though, the Item Transmutation button is still greyed out. Why is this happening?

Ah, no, I figured out what it was. I was unaware that you had to right click the one that you wanted the transmuted item to appear as…
Sorry, lol. Thanks for the response though! xD;;

Are you wearing one of the items? You can’t be wearing either whilst carrying out a trans.

Un- equip the item your wearing, that you want to transmute. If you are currently wearing it. Then try again.
