Nether-Stalker Mah'duun wants you to kill 3 Malicious Instructors. Return to him in Shattrath's Lower City once they all lie dead in order to collect the bounty.
- Kill Malicious Instructor × 3
Mah'duun has heard it said that none are as cruel as the six-armed demonesses inside the Shadow Labyrinth.
Go to Auchindoun, seek them out, kill them all.
If you cannot accomplish so simple a task, we do not have anything further to say to one another.
