Killing Bosh Bosh
From Drunkapedia
Speak to Kukuur in Kor-Gursha.
Kuuru tells you, "Prepare to hunt down the most degenerate boil this land has ever been afflicted with. A Kukuur named Bosh Bosh has been stealing into our town at night and taking our young! He... eats them."
Kuuru tells you, "He must pay for every innocent life he has taken! He makes the Deep Guruk Caverns below the Southern Catacombs his home. Do not rest until you have hunted that filthy scum down and made him pay."
Kuuru tells you, "Do not fail me on this. Bring me proof of his demise and I will reward you well for your help."
