As two actions, you conjure a phantom watchdog in an unoccupied space that you can see within 5 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 5 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.
When you cast this spell, you can designate any number of creatures you can see to be unaffected by it. A creature that moves within 1 meter of the spell’s area for the first time on a turn or starts its turn there must make a Reflex saving throw.
On a failure, it takes 2d12 piercing damage.
On a critical failure, it takes twice as much damage.
On a success, it takes half as much damage.
On a critical success, it takes no damage.
The hound vanishes when it has dealt a total of 50 damage.
