By means of this spell the magic-user summons up a phantom watchdog which only he or she can see. He or she may then command it to perform as guardian of a passage, room, door, or similar space or portal. The phantom watchdog will immediately commence a loud barking if any creature larger than a cat approaches the place it guards. As the faithful hound is able to detect invisible, astral, ethereal, out of phase, duo-dimensional, or similarly non-visible creatures, it is an excellent guardian. In addition, if the intruding creature or creatures allow their backs to be exposed to the phantom watchdog, it will deliver a vicious attack as if it were a 10 hit dice monster, striking for 3-18 hit points of damage, and being able to hit opponents of all sorts, even those normally subject only to magical weapons of +3 or greater. The faithful hound cannot be attacked, but it can be dispelled. Note, however, that the spell caster can never be more than 3” distant from the area that the phantom watchdog is guarding, or the magic is automatically dispelled. The material components of this spell are a tiny silver whistle, a piece of bone, and a thread.
