Transparency

For the duration, an object you touch becomes transparent to your eyes only and you gain vision of what lies on the other side. The object retains all other properties, so if it would normally block sound it continues to do so as normal. The object can be no larger than a 5 foot cube. If the object is larger than that, such as a 10 foot by 10 foot wall, only a five foot diameter circle or square is affected.

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.
