for all the melee's trying to take him down solo, his defense is immense. When I did it:
75 whm/nin
60 blm/whm
51 rdm/whm
51 war/nin <-- me
I spawn it and we start fighting. the whm is trying to hold hate with flash and cures, but i keep grabbing hate. He said "dont voke!". I go "i havent". anyway, we're hitting for like 20-30 a hit. then the rdm has a great idea and casts dispel. he hadnt cast anything, but it said "Protect affect wears off" we started hitting for 50-60. of course this was at his 25% hp, so it went fast after that.
