Set Alarm

Using Set Alarm, a caster can set a mental or audible alarm (decided by the caster at the time of casting) that triggers each time a creature of Tiny size or larger enters the warded area. Any creature that speaks the password (determined by the caster at the time of casting) does not trigger the alarm.

If the alarm is mental, the caster, as long as they are within 2km of the warded area, will receive a mental signal which awakens the caster from sleep but does not otherwise affect concentration. A mental alarm is not affected by a silencing effect.

If the alarm is audible, the alarm, when triggered, creates the sound of a siren which can be heard clearly 20m away and, in quiet conditions, up to 60m away. Those affected by a silencing effect cannot hear the alarm.
