It's actually a pretty easy fight using the perfect defense>zerg strategy. You have essentially 4 minutes of semi-invincible between 2 perfect defense and fanatic's drink. Not that you need that much time considering each melee can 2hour twice, and you can get a million drinks from the chest.
Doubting bullwhip belt drops from this. Each NM only had 1 rare/ex drop, so I don't think this would suddenly have 2.
