I have tried to kill this guy at a lower level (maybe 40's) and got creamed. I tried it again today at lvl 67 (sk) AND used my Harmtouch that does 8376 points. in that amount of time (attack,bash,harmtouch) i got him down to 65% hp, WHICH WAS EQUAL TO WHAT HE GOT ME DOWN TO!!! 65%. I dont know what this guy holds or what but it has 0-1 delay and his hp is enormous. (Harmtouch does a continuos 3686 about every 3 sec for apx. 21 sec's) He healed so fast that the 3000+ damage every 3 sec's brought him down apx 9-10% and he got it back before the next one even hit!
Maybe again at lvl 85! Or have me 67 SK,67 healer merc, 70 Pal, & 70 tank merc.
I'll have harmtouch and lay on hands.
