You do not need eyes to see, so you can sense victims in darkness, smoke, mist and through similar obstructions. You never suffer Impairment or penalties for poor visibility. Others can still sneak up on you, but you can use Powers instead of Perception against supernatural forms of invisibility, such as the Lurk or BlurForm.
Taking this schtick additional times gives you the ability to sense victims even when they are behind walls. This sense has a range equal to your Magic in meters times the number of additional schticks.
