Quest:Don't Kill the Fat One

Objectives
Kilrath in Terokkar Forest has asked that you kill 10 Boulderfist Invaders and beat Unkor the Ruthless until he talks.
 * Unkor Submits
 * slain (10)

Description
I have been watching these beasts for days. The fat one says that he is waiting for something. What he is waiting for, however, is a mystery.

I have a plan but it is going to involve some violence on your part. You will need to kill several of his subordinates and then beat him within an inch of his life. Do this and I am certain he will tell us everything that we need to know.

Completion
Let me live and I'll tell you whatever you want to know!

Gains
Upon completion of this quest you will gain:
 * 11000 XP (or at level 70)
