The centaur leadership relies on a core of trusted, disciplined warriors to keep the others in line. If we reduce their numbers, the Kolkar will have no might with which to support their rage. And so, I have a bounty task for you.
Around the Lushwater Oasis to the south, slay Kolkar Marauders and Stormseers to collect their bracers. Return when you have a heap of these trophies and the Horde will reward you well.
