My group was 35-36 and this dropped. We were doing a difficult adventure though. I won it in a roll, this is great for my 35 cleric. (This is my main, so no twinking for me)
This was a good drop for my LVL 38 Druid...won it in a roll. Pretty nice for me, at least until I can afford something better since this is my main. Wisdom and mana are my main need right now =)
Nice isnt it got one for my cleric from MM, usually there is only one named in a dungeon, so play a lot of LDON... my group went from 39-45 and the mask dropped.
loaded this item 2 days, from 2 different named mobs, in Mistmoore Catacombs. 2 different sub zones, but it was definately in mistmoore catacombs both times. the groups were around level 45, as i was playing my 45th monk.
i have no clue what the monsters names were. they were almost exactly like normal monsters, except with no "a" in front of their name.
