The Dark poison is a cruel affliction, indeed. But to craft the cure, I will need special ingrediants. The most important is the heart of the Nightbane Toad. A rare creature, it only emerges under the cover of night near the murky waters of Thronefast and Avendyr’s Pass. You’ll also need to gather a vial of Ratkin Blood and a Brightcap Mushroom. Bring these to me, and I will create the antidote. But beware - gathering these ingrediants is full of dangers.
