You set an alarm against unwanted intrusion. Choose a door, 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. You can designate creatures that will not set off the alarm.
