A power of the scrying subdiscipline creates an invisible sensor that sends you information. Unless noted otherwise, the sensor has the same powers of sensory acuity that you possess. This includes any powers or effects that target you, but not powers or effects that emanate from you. However, the sensor is treated as a separate, independent sensory organ of yours, and thus functions normally even if you have been blinded, deafened, or otherwise suffered sensory impairment. Any creature with an Intelligence score of 12 or higher can notice the sensor by making a DC 20 Intelligence check. The sensor can be dispelled as if it were an active power. Lead sheeting or psionic protection blocks scrying powers, and you sense that the power is so blocked.
