Bloodhound

You mix your own blood with that of the target to conjure a terrifying, spectral bloodhound that is bound to you both. The hound is loyal to you and always knows the direction and distance between it and the creature whose blood you used in the summoning, as long as they are in the same plane of existence. It can move up to 90 feet towards the target of the spell, but can take no other actions. If the target is moving, it knows the direction of its movement. While the hound is within 500ft of the target, the target can sense its location and movement the same way the hound senses the target.
