Death Sense

For the duration, you can feel the presence of undead, deceased, or dying creatures within 30 feet of you, as well as where they are located. If the creature is on the verge of death, you have a general idea of how much longer they have left to live. The spell becomes overwhelming and immediately ends if the number of targets is greater than your Constitution score. 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.
