Slay 6 Dreadspinner Tenders and use the Shado-Pan Dragon Gun to destroy 20 Dreadspinner Eggs in the Terrace of Gurthan. Provided item: Shado-Pan Dragon Gun (quest item)
 * Dreadspinner Eggs destroyed x20
 * slain x6

Description
We're holding, but just barely. Anything you can do to stem the tide of dreadspinners coming up the wall would be a big help.

Feel like tearing open spider eggs one at a time by hand?

I didn't think so. Take one of our dragon guns and light it up down there. I wanna hear those puppies pop.

Progress
Hey, help me out here!

Completion
Nice work with that dragon gun. I did what I could down here, but arrows are only so useful against these things.
