Alarm

You set an alarm against unwanted intrusion that alerts you whenever a creature of size Tiny or larger touches or enters the warded area. When you cast the spell, choose any number of creatures. These creatures don't set off the alarm.

Choose whether the alarm is silent or audible. The silent alarm is heard in your mind if you are within 1 mile of the warded area and it awakens you if you are sleeping. An audible alarm produces a loud noise of your choosing for 10 seconds within 60 feet.
