Guild Wars 2

Is there any way to get sigils and runes off of armor and weapons without destroying the item?

I have a rabid set of armor and weapons that I use for pve and wvw but I need to change the runes and sigils because my traits change. There has to be a better way then grinding another set of armor with the same stats just to put different things in the item slots right?

No. you can use a Black Lion Salvage kit to get the rune back as well as some mats and ectos, but if you want the rune you have to destroy the item.

You can also overwrite the runes/sigils if you want to keep the armor but just change the runes/sigils.
