The Elder Scrolls: Tamriel

While wearing this ring, you can use an action to speak its command word and see through solid matter for 1 minute in a 30-ft. radius. Solid objects appear transparent and let light through. The vision penetrates 1 ft. of stone, 1 inch of common metal, or 3 ft. of wood or dirt, but is blocked by thicker materials or any lead. Using the ring again before a long rest requires a DC 15 Con save or you gain 1 level of exhaustion.
