Guruk Fiend Kill Task
From Drunkapedia
Speak to Mohor in Kor-Gursha.
Mohor tells you, "If there's a more dangerous Guruk than the Guruk Fiend I don't know of it. They are more cunning than the average Guruk and stronger too. They've been trying to get into our town's caverns ever since Torgluuk passed through. Go and kill 30 of the cunning fiends lurking in the lower Southern Catacombs and I'll reward you for your help."
