he is VERY high MR, my AT hardly hit him after tash. He can be partially slowed, but very hard, should bring a 65 ench and at least 1 more type of MR debuff. He procs a 1k damage hard to resist proc, so even with a defensive warrior you need to be careful
Mob was very magic resistant, on first try we had some bad luck got partial slow in. Didn't land any magic spells after that, landed disease slow later but didn't really see it, just didn't get a resist msg so not sure if landed full or what. First time just used malo, later had tash on mob also and still couldn't land magic spells. Poisons and ice seemed to land easily. Dropped rune, earring and the quest ring and some other junk I didn't notice.
