i dont know, but assa was pretty easy, but at least somewhat intense at his IL
sub became faceroll the moment i realized that with enough high graphic setting you can see xylem in arcane phase and last phase was a joke, i did it the second time thanks the snare talent for the dot.
combat i bishotted it without even knowing what to do but at 965 IL
(i play only assassination and used the other spec basically only for the challenge)
