Bring Kum'isha Imperfect Draenethyst Fragments. Any form of monster in the Blasted Lands could be carrying a fragment.
Well, after that display of voracious greed, I feel nauseous.

For each imperfect draenethyst fragment you turn in, I shall reward you with more junk. My junk heap gets smaller while your junk heap gets larger. On Draenor we call this a 'win-win' situation.
