Blood Sense

For the duration, you sense the presence and location of blood, injured creatures, and any blood diseases or disorders within 30 feet of you. You also identify the type of blood in each case. Similarly, you know if there is a place or object within 30 feet of you that has been bloodied.

The spell can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.
