Here's a quick video of the fight. As you can see, the Cow Queen set wasn't the best choice for this set up but I wanted teleport and MF. I'm using Frostmourne but any damage source will do. Elemental procs seem to hit harder when combined with a lvl 25 conviction aura. In the video I'm using a 1 point Salvation aura because I was lacking fire resist Hope this helps.
