concentration, 1 minute/mana

As two actions, you gain the ability to see through solid objects to a range of 5 meters. Within that range, you have darkvision if you don’t already have it. For the duration, you perceive objects as ghostly, transparent images.

The spell can penetrate most barriers, but it is blocked by 30 centimeters of stone, 2 centimeters of common metal, a thin sheet of lead, or 1 meter of wood or dirt.
