During (and after) my tenure, I am not aware of any specific nerfage to drow shamans and their maledictive levels. This does not preclude the possibility that one was put in without my knowing, but I doubt that; an IMP who knows more might comment if I am wrong. By and large, I think that settles this question. Thread locked. Thanks.
