Blood Sense

The caster focuses on a living creature, or undead that has blood in its body such as a Vampire or Zombie. The blood of the caster will trail 1 foot from the caster in the direction of the creature they are focusing on as long as the creature is within 1,000 feet. They must know the creature well enough to visualize their face. Alternatively, if the caster knows their true full name, the blood will trail to the closest available target with that name. This spell can’t locate a creature if any thickness of lead, even a thin sheet, blocks a direct path between you and the creature.
