Appraisal of Mammon

You point at a creature or container and a voice whispers in your ear how rich they are. You instantly know the total gold worth of the equipment and coin carried by a creature you can see in range. Alternatively, you may choose a container you can see in range to learn the total gold worth of the equipment and coin held within the container. If the container is thicker than 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood, the spell is blocked.
