Blood Tracking

Swallowing one drop or more of a creature‘s blood, as part of this spell, will allow you to discern their exact location. You need not concentrate on this spell and will be aware of a creature’s location constantly, as long as they are on the same plane as you. If a creature is on another plane of existence, you will only know which plane they are on unless you move to that plane as well. You do not know what surrounds them, only their exact position in space.
