Diablo 3: Act 3 Boss : Siegebreaker Assult Beast. As I mentioned earlier, the biggest gain to my recent play, especially in nightmare, is getting around 100+ health on hit spread over my items. If you have this and similar damage/health to mine, even with the worst micro in the world, you should still be able to kite this boss around and avoid his charges with Smoke Screen. My main dps for this was again Impale with Chemical Burn. No grenades this time, but I'm having great fun and success with them in normal play. Music by Kill Kasper.
