Creates a subtle ward on an area you select. It sounds a mental or audible alarm each time a creature of Tiny or larger size enters the warded area or touches it. A creature that speaks the password (determined by you at the time of casting) does not set off the alarm. You decide at the time of casting whether the alarm will be mental (1 mile) or audible (60 ft) in nature.
