Casting Time: 1 minute
Range: 25 feet
Duration: 8 hours
Choose a door, a window or an area within range that is no larger than a 20-foot-cube. Until the spell ends, an alarm alerts you whenever a tiny or larger creature touches or enters the warded area. When you cast the spell, you can designate creature that won’t set off the alarm. Also, choose whether the alarm is mental or audible.
A mental alarm alerts you with a psychic ping if you are within 1 mile of the warded area. The ping awakens you from sleep.
An audible alarm produces the sound of a hand bell for 10 seconds. Anyone within 50 feet of the warded area can hear the bell. Reduce the distance by 10 feet for each interposing closed door and by 20 feet for each interposing wall.
A tiny bell and a piece of fine silver wire.
