Quest:The Perfect Stout

Objectives
Bring 6 Shimmerweeds to Rejold Barleybrew in the Brewnall Village.
 * Shimmerweed (6)

Description
I'm on a quest, a quest to make the perfect stout. I know I can do it—brewing's in my blood. I just need to find the right recipe... The Frostmane trolls grow a plant, shimmerweed, high up in the hills to the east. They use it in their strange, tribal rituals. We dwarves haven't found much use for it, but it has a unique taste...and I want to experiment with it in my brews! Get me some shimmerweed from Frostmane seers, or swipe it from the trolls' shimmerweed baskets.

Progress
Do you have that shimmerweed? I almost have a batch of stout ready to brew, and I want to try throwing the weed in with this mixture.

Completion
Great! I can't wait to use these in some of my recipes. There's one in particular I think it'll work great in...
