Dark Reign - Diseased Pumas
For this task you need to go to the Broodlands. Once you zone into the Broodlands (north out of Lavastorm Mountains) follow the blue line on your compass to your quest objective. (If you don't currently have your compass up hold ALT down and press D (Alt + D)).
For this task you need to find 4 Infected Pumas inside Stillmoon Temple, kill them and loot 4 Infected Puma Bloods. Each of the Pumas has a static spawn location that never changes (a map of where all four are located can be found below). I usually pull the entire zone and end in the final room with the last Puma furthest to the south.
An important piece of information if you plan to do this is no mobs in the entire zone summon, except for the Pumas. So be sure not to have a damage shield active or anything like that or you'll be in for aggravation.
