Detect Good and Evil | Action

For up to 10 minutes, you know if there is a non planar creature nearby. Similarly, you know if
there is a place or object within 30 feet of you
that has been magically consecrated or
desecrated.
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.
