⌂ Beyond the Darkness... what lies out there? M > Mage’s Faithful Hound (Conjuration, Magic)

[Excerpt from S.T.R.I.X. archives]

If I well understood, the Initiate conjures up a phantom watchdog that is invisible to everyone but herself. It then guards the area where it was conjured (it does not move).
The hound immediately starts barking loudly if any dog-sized or bigger 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. [Note: Remember to search for the Illusion School for details]
If an intruder approaches to within 5 feet of the hound, the dog stops barking and delivers a vicious bite. 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 spot. Its bite is the equivalent of a magic weapon for the purpose of damage reduction. The hound cannot be attacked, but it can be dispelled.
The spell lasts for hours, but once the hound begins barking, it lasts only seconds. If the Initiate is ever more than 100 feet distant from the hound, the spell ends.
As for any Magic, using this spell is taken by Enquire as a severe crime, punished with Annihilation or even death sentence.
