Watchware, 30' Radius (Wizard Spell)

The wizard can place this improved version of the watchware spell on any fixed location chosen by the caster. If that area is entered or dis­turbed at a later time, the caster is alerted. This alert occurs even if the caster is asleep or uncon­scious, but not if the caster is turned to stone or otherwise unable to think.
The original caster will receive a mental im­pression when the watchware is activated. This mental image gives some hint of the nature of the disturbance within it at the time of activation. The impression lasts only a single round and does not include any sound. It interrupts concentration and disrupts spellcasting in progress, but does not dis­turb the wizard in any other way.
The ward is activated when the area is dis­turbed for any reason, whether someone enters the sphere, pokes into it with a pole, a cat walks on it, or an earthquake shakes it. The area protected by the watchware; 30-ft. radius radiates a faint aura of magic. If a dispel magic is cast upon the watch­ware, it will activate. The watchware functions only once, then the spell is spent. A wizard can have as many active watchwares of all types as he has levels, but in practice most keep only one or two to avoid the hassles of accidental activation.
The material components of this spell are a spider web, a small brass or silver bell, and pow­dered glass, which is sprinkled in a circle about the caster.
Notes: Very rare spell from the Forgotten Realms setting.
