Talk:Outsider's Mark/@comment-28380995-20160802202750/@comment-16533050-20160802224624

ah sorry, I meant passive in terms of nothing is done on Corvo's part other than activating it. But yes, Dark Vision is technically an active ability as you have to spend mana on it and have to choose for it to be activated. My apologies on that.

I think the Mark only glows when its power is being used, and then again (to me at least) can only be seen by those marked by the Outsider.

I don't know if there is any outside indication as to whether or not the Dark Vision (or Void Gaze in Daud's case) - such as the user's eyes being mirrored over or something like that. In my head-canon there is, but only for the moment of activation - however, that is neither here nor there.
