Your magic causes a humanoid skull to float 5 feet off the ground, facing a direction you choose. It monitors a 60 foot cone in that direction, subject to sight lines. If a living creature enters that area, it utters a piercing shriek which can be heard for hundreds of yards, then falls to the ground, its magic spent. Provided you are on the same plane of existence as the skull, even if you can’t hear it you are aware of it when it is triggered.

Every creature other than you within 30 feet of the skull when it activates must make a successful Constitution saving throw or be deafened until the end of its next turn.

The skull can be destroyed by a creature which approaches from a direction not part of its monitoring zone. The skull has AC 12, 10 hit points, is resistant to slashing and piercing damage, and is vulnerable to bludgeoning damage. You are not made aware of the skull’s demise if it is destroyed without triggering.

The skull’s magic works until it is triggered or the next dawn.
