Perimeter Alarm
3ap 1 Minute 1 | Circle of Abjuration
Spell

You set an alarm against unwanted intrusion. 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 creatures that won't set off the alarm. You also choose whether the alarm is mental or audible.

A mental alarm alerts you with a ping in your mind if you are within 1 mile of the warded area. This ping awakens you if you are sleeping.

An audible alarm produces the sound of a hand bell for 10 seconds within 60 feet.

With a whispered incantation, an invisible barrier forms, threading through the air like delicate wire. You envision a subtle trap, ready to alert you with a silent ping or ringing chime the moment an intruder crosses it.
