You touch a simple surface such as a door, a wall, or even a shield to see through it as if it was transparent. The target area can vary from 1 to 5 square feet, as chosen when the spell is cast. The surface appears to be non-existent from the side of the caster, yet the other side remains completely normal and solid.

The spell can see 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.
