I decided to level up a new nightblade toon and went to Reaper's March a bit early. To my surprise, half of my magic attacks (Funnel Health, Impale) were doing 0 damage some times. That never happened against npcs in the 5 level range but that area is 40-45 and I'm 32. Is that a known bug or I just should not be there. I do get the xp I need when I manage to kill.
