Since the accident, all Gnoarn thinks about or talks about is cleansing Gnomeregan of the trogg infestation and finding a cure for the sickness that plagues it, <name>.
Luckily, Razzle and I are close to some kind of cure - either that or the recipe for a really powerful rum. We won't know until we test! Naturally, in order to test our theory, we're going to need a few things; namely, fallout from the irradiated troggs in Gnomeregan. Fill up this phial with the green glow and bring it back!
Can't you see we're trying to cure an entire species of gnomes here??! We need more of the green glow!
Completion
Excellent work! The time has come to test the new formula. If this works, not only should that captured leper gnome be cured, but I should have a full head of hair! Stand back!
The previous quest (The Day After) is NOT required to receive this quest.
You need to Use the [Empty Leaden Collection Phial] on one of the troggs that glows green (Irradiated Invaders and Irradiated Pillagers). There are many of these outside the instance. You can harvest the radiation from a corpse, but it can fail; you may need to try a few times.
You may want to either leave Gnomeregan when you complete this quest, or complete this quest prior to entering, as you get a follow-up quest that requires you to enter the actual instance.
