Maybe darkblood would destroy it? Not dissolve it, but--just stop it from existing. We can try that with corruption, couldn't we? Even if it does sound weird that the relics are better with dealing with corruption, but all it does is suck it up.

[ Like, huh. That's weird. He can get why Palamedes is cautious about 'where does corruption go' when something so useful doesn't just...get rid of it. ]
