Every week this summer, we’re challenging you to get together with a few friends to explore a part of Azeroth that you may not have seen in a while, or perform a feat that you may have never done. We’re calling them World of Warcraft Summer Challenges, and we’re going to be playing along with you as we hunt down rare achievements, get screenshots of amazing bosses, and try to find some rare gear for our transmogrification sets.

In this thread, we're talking about this week's challenge, posting stories about experiences completing it, and linking to screenshots.
