Target: One ally

Effect: The target takes necrotic damage equal to your Intelligence modifier. Until the end of the encounter, while you have line of effect to the target, you can see as if you are in both your space and the target's, and when you use a wizard attack power or a wizard paragon path attack power, you can do so as if you were in either space, although you physically remain in yours.
