Kill 10 Magmoth Shaman, 5 Magmoth Foragers, 3 Magmoth Crushers, and 3 Mates of Magmothregar. Then, return to Ortrosh at Bor'gorok Outpost.
The overlord refuses to allow the shaman to heal my wounds. He says that it will be a good lesson for me and give me time to reflect upon my failure.
But you could get revenge for me and the others who fell at Magmoth!
I know that the spirit talker wants you to go in there to save the farseer.
It's just to the east. Go, [class]... go slay the magnataur and their snobold servants. Regain the outpost's honor!
