Mass of Spite  

After 2 wipes took him down twice today, (back to back pops) with 100 mage, 4500 AA group geared, 95 chanter 1800 AA, 82 ranger 1500 AA. All 3 using cleric mercs, higher 2 J5's, 82 one T5. The trick for me was switching to earth pet. I tend toward the air pet usually but the raw HP of the earth seem to be the difference with how this guy hits since the change. I use the mage pet ward as it would pop, the delay mage heal spell, not the regular heal at all. Servant as it pops, malosenia seemed to be resisted all the time, most of my fire based spells resisted half the time, tried the elemental rain, resisted every time.

Positive stuff- He is easy to single pull on the cave side of the bridge and he popped in both PH spots. If you stand next to the rockpile near the cliff you won't attract any of the bats as adds. Just watch out for the 2 patrolling guards walking back and forth on the bridge.

dropped the rare ear both times and the helm armor piece once.
