Bring 15 Centaur Bracers to Regthar Deathgate, west of the Crossroads.
The Kolkar are a threat to the Horde's claims in the Barrens; we must reduce the numbers of their troops. And so, I have a bounty task for you.
While in Kolkar territories, slay their warriors and collect centaur bracers. Return when you have a heap of bracers and the Horde will reward you well.
