Hmm, I used Anubisath Idol and an Infected Faun just for kicks and they one shotted him. Anubisath uses Crush, Stoneskin and Deflection. The faun I had set up with Siphon Life, Adrenaline Rush, and Fury. I wanted an undead for the Frost Breath and Shadow Flame. And I haven't used the faun for anything so I figured why not. I didn't even get a chance to record to post it. After reading the post I went to just test and they crushed him. I'll keep testing a few more just for kicks to see what we can come up with!
Update: Swapped the Faun out for Stitched Pup. Completely destroys the Undead with Howl and Flurry and Consume Corpse.
