This blade dropped on Morden Rasp server this evening. Unfortunately, the blade no longer has a dmg bonus of 11... it now has NO dmg bonus. The picture is incorrect.
Taskmaster Crizz spawns at roughly -1150, -540, inna liitle alcove with several other gobs. His PH is a regular taskmaster and can be single pulled because of the very small aggro radius the Nurgan mobs have. The sword is his rare drop(have only seen it once inna bout 15 to 20 kills) and you will see it in his hand. If he's not holding a sword you get the Great Axe of Decapitation.
