Collect 2 Vials of Corrosive Spit from the Jormungar by using the scraper on yourself. Bring the vials back to Zort in the Crystal Vice when your task is complete.
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.
