Detect Life

For the duration, you know if there are any living creatures within 30 feet of you, as well as where the creatures are located. This spell cannot detect the presence of any constructs or undead. You can pick up on subtle vibrations and a small red glow becomes visible allowing you to pinpoint a creatures heartbeat.

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.
