Messy Business

Even at first glance, the sample you brought me shows obvious signs of some kind of corrosive spit. It would be a natural assumption that the same substance these worms use to burrow through the ground has allowed them a formidable weapon against the Ice Giants. Take this scraper and pick a fight with some of the worms. When they spit on you, use the scraper to remove it and bring it back to me. Get me a couple samples - I'm going to have to use it as the base for an elixir.
