Detect Life

Detect Life allows you to see where lifeforms are that have blood flow (the dm is to decide what creatures have blood flow).

When you cast this spell, your eyes glow with whatever source you get your power from. Any creature that pings for you gives off a reddish hue that only you can see. You can see this reddish hue up to 100ft radius through 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.

Higher level casting: This spell can be cast at 4th to increase the search radius up to 500ft radius, 6th to increase the search radius up to 1,000ft radius, and 8th to increase the search radius up to 2,000ft radius
