Helm of the Third Eye

+1 AC
Wearer may cast clairvoyance 3/day
(Create an Invisible sensor within 1 mile in a
Location familiar to you, or in an obvious
Location that is unfamiliar to you (behind a door,
around a corner etc.) The sensor remains in
place, and it can not be interacted with.
When cast, choose seeing or hearing. Use that
through the sensor as if you were in its space.
As your action, you can switch.)
