Alarming Ring

This ring is cleverly worked of brass and nickel, with a tiny knob marked with numerous notches on it and the bezel below it. 

The ring has 1d3 charges, and regains 1d3 charges daily at dawn. As an action, you can turn the knob clockwise and cast the Alarm spell. If you choose an audible alarm, the ringing noise also is produced from the ring. This does not consume a charge.

As an action, you can turn the knob counter-clockwise to cast the Fear spell, using a DC of 15. This consumes 1 charge.

When the last charge in the ring is used, roll a d20. If you roll a 1, the Fear spell produced by the last charge is instead directed 180 degrees in the opposite direction and includes you in the cone.
