The Elder Scrolls: Tamriel real

For the duration, you sense the presence of living creatures within 30 feet of you. Creatures you can't see appear as glowing outlines, allowing you to detect their presence, even if they are behind walls or obstacles. 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. The spell lasts up to 10 minutes and can be maintained with concentration.
