The target is left unconscious as their blood is drained from their body and a blood-based phantom appears 10 feet away from their body. This phantom can travel through cracks and small openings as small as 1 inch in diameter and can revert to a puddle of blood to hide. The phantom cannot take damage, and cannot attack, nor can it lift anything. If the phantom dissipates before it is within 10ft. of its body, travels further than 250 feet away, or the caster concentrating on this spell breaks concentration, the target is awoken in their body and takes 8d6 necrotic damage. If the phantom returns to its body, the creature suffers no ill effects.
