As an action, you conjure a phantom watchdog in an unoccupied space that you can see within 9 meters. The hound occupies that space and is invisible to all creatures except you and can’t be harmed.
When a Small or larger creature comes within 9 meters of it without first speaking the password that you specify when you cast this spell, the hound starts barking loudly. The hound sees invisible creatures and can see into the Ethereal Plane. It ignores illusions.
Any creature hostile to you that moves to a space within 3 meters of the hound for the first time on a turn must succeed on a Reflex saving throw. The creature takes 3d6 piercing damage on a failed save, or half as much damage on a successful one. The hound vanishes when it has dealt a total of 70 damage.
You can increase the damage by 2d6 and the maximum damage increased by 40 for each additional mana or psi expended.
