The Butcher, from the first Diablo game. First, I tried using a bow, and I was going to close the door to see if it would stand still. Unfortunately it always blocked the door, so this happened... it took so long I commited suicide and tried something else. If you get lucky like I did you will find a blood fountain. You can also try and skip the butcher to level up some more and then come back.
