Ring of the Spying Eye
Rare Wondrous Item
Eye Spy. You can take off this ring and put it flat against a surface to be able to see through the ring and the surface as if you made a hole into it. You can look through 5ft. of stone, wood or dirt, 5 inch of common metal or a thin sheet of lead. The hole is effectively an illusion but also appears on the other side of the surface. No materials, objects or sounds can pass through the hole. When you remove the ring from the surface, the hole disappears and leaves no trace in the material.
