This spell took ten minutes to cast and lasted a few days to many days, depending on the level of the caster. The spell covered a sphere with a radius of 25 ft (7.6 m) centered on a point. The effect of the spell was very similar to the alarm spell, except the trigger was a person or object that had previously been tagged with the caster's arcane mark. When such a person or object crossed the perimeter of the sphere in either direction, the caster was alerted by a mental touch that was noticeable without breaking concentration. If the caster was in a natural sleep state, he or she was awakened. The caster had to be within one mile (1.6 km) of the ward in order to receive the alarm.
