Description: You conjure up a phantom watchdog that is invisible to everyone but yourself. It then guards the area where it was conjured (it does not move). The hound immediately starts barking loudly if any small or larger creature approaches within 30 feet of it. Those within 30 feet of the hound when it is conjured may move about in the area, but if they leave and return, they activate the barking. The hound sees invisible and ethereal creatures. It does not react to figments, but it does react to shadow illusions.
If an intruder approaches within 5 feet of the hound, the dog stops barking and delivers a vicious bite (+10 attack bonus, 2d6+3 points of piercing damage) once per round. The dog also gets the bonuses appropriate to an invisible creature. The dog is considered ready to bite intruders, so it delivers its first bite on the intruder's turn. Its bite is the equivalent of a magic weapon for the purpose of vulnerabilities. The hound cannot be attacked, but it can be dispelled. Once the dog starts to bark, the spell expires in 1 minute. The spell also expires if you move more than 100 feet from the hound.
