Surveillance

You touch an object or surface and create an invisible sensor on the side opposite of where you touch. The spell can penetrate up to 5 feet of most materials, but fails to penetrate lead. If you cast the spell on a hollow object, such as a wooden crate, iron chest, or stone sarcophagus, you can create the sensor within the object. The sensor remains in place for the duration, but becomes dormant if you aren't touching the initial spot.

When you cast the spell, you choose seeing or hearing. You can use the chosen sense through the sensor as if you were in its space. While seeing through the sensor, you have darkvision out to a range of 10 feet. As your action, you can switch between seeing and hearing.
