Clairvoyance

You create an invisible sensor at a location familiar to you or in an obvious location within range. You can see or hear through the sensor as if you were there.

A familiar location is a place you have visited or seen before, and an obvious location may be behind a door, around a corner, or in a grove of trees.

The sensor remains in place for the duration, and it can't be attacked or otherwise interacted with.

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. As your action, you can switch between seeing and hearing.

A creature that can see the sensor with see invisibility or through truesight sees a luminous, intangible orb about the size of your fist.
