Rift Quest:An Endless Rabble  

Head straight south out of the encampment and you'll find yourself in a field full of Endless Cult members and Deranged Defiants. Be careful of your surroundings here as you can accidently aggro multiple monsters here. Slay five Endless Reavers and five Endless Sorceresses in these fields and then return to Warden Mordin to claim your reward.
