Guild Wars 2

Is there a tool to extract an upgrade without destroying gear? I have a black poly aura gem on my Mesmer that I might want to try on my necro at some point and didn’t realize it would be so dark. The mes backpack isn’t that great so I could salvage it if I get desperate but would a black lion salvage kit absolutely save it or could the poly upgrade still b destroyed?

Yes, but it’s only available on the gem store. A black lion kit would destroy the item the upgrade is in, but it has a 100% chance to get the upgrade out.
