This was pretty miserable fighting the actual boss. I had to change back to a Jack the Axe and a proper six link to kill him and even then it was slow, but not hard.
This build is I think really good to start out with because it needs absolutely (actually) no good gear to at least clear the map portion of T16s pretty comfortably. DPS is not good by any means. This character with a Jack and no awakened gems has about 1m dps, with awakened gems and at level 95 the dps goes up to 1.5m.
Why sunder?
It clears better than most if not ALL slam skills once you have gem levels and the helm enchant, Anomalous makes it better.
