It does Teganze and Dunc easily. Not as fast as ww barb or neutraldin, though. Decent boss killer with max Dreameater. Does well in T4 uniques but really need top end gear to do 125 ubers without too much struggle. Fauzt is tough without big damage.
I played with it a little and it did not impress me. This lance is flying too slowly and too close. This life-stealing skill is ok. We'll wait until he does Tolls so that you can try a build like you have all high end items.
