A feeling in the back of your head tells you that someone is definitely watching.

You immediately become aware of any attempt to observe you by means of a divination (scrying) spell or effect. The spell’s area radiates from you and moves as you move. You know the location of every magical sensor within the spell’s area.

Augment: You can Augment this spell in one or both of the following ways.

  1. If you spend 2 additional spell points, you and the scrier immediately make opposed caster level checks (1d20 + caster level) whenever this spell causes you to detect a scrying sensor. If you at least match the scrier’s result, the scrying spell effectively works both ways, as if you had cast the same spell on the scrier (or centered on his area, as appropriate). This does not end the scrying spell. If the scrier also had this augmented version of Detect Scrying active when he cast the spell, he gains awareness of the fact that you are staring back at him (due to the spell’s base function, but he does not get another sensor at your location due to you scrying on him.

  2. If you spend 4 additional spell points, you can use the scrying sensors you detect as a tunnel into the scrier’s mind. First, you must successfully make a scrying sensor work both ways, as with the first augment of this spell. For as long as the scryer’s spell lasts, can then cast any Mind-Affecting spell on the scryer as if you had line of effect and line of sight to the scryer, and the scryer were within range of the spell.
