It was either one of these or the hovoc blades that droped a very nice pair of melee gloves. It was not a named, just standard mob.
I can not remember the exact stats on gloves but they were something like +5 to all stats and saves and 33 or 36 percent haste. They were also no drop.
Have noticed that these creatures seem to drain mana. Our SK who was holding agro seemed to lose all his mana during each battle. Any confirmation on this?
