Demon in Disguise

While you were... working your magic on that demon, I was able to make headway in distilling the corrupted essences down to a simpler, more manageable form. I've asked Khadgar to provide you with the concoction once he's had a look, but I must remind you - these essences are quite potent, often dangerous if not handled with the utmost of care. Speak with Khadgar when you are ready to begin.
