Bloody Bone Necklaces

I was sent to Grom'gol to aid Nimboya on his quest, but... I too have reasons for being here. The Bloodscalp tribe is enemy to our tribe. Collecting trophies of our enemies gives us power over them. You may aid our tribe by hunting our enemies. They dwell to the north. Slay Bloodscalp trolls and take from them their bloody bone necklaces. Collect many, and your reward will be great.
