Ring of X-Ray Vision

Description:

This ring gives its possessor the ability to see into and through substances that are impenetrable to normal sight. Vision range is 20 feet, with the viewer seeing as if he were looking at something in normal light. X-ray vision can penetrate 20 feet of cloth, wood, or similar animal or vegetable material, and up to 10 feet of stone or some metals (some metals can’t be penetrated at all)

Substance Scanned Thickness Penetrated per Round of XRaying Maximum Thickness
Animal matter 4ft 20ft
Vegetable matter 2 and a half ft 20ft
Stone 1ft 10ft
Iron Steel etc 1in 10in
Lead Gold Platinum nil nil

It is possible to scan up to 100 square feet of area during one round. Thus, during one round, the wearer of the ring could scan an area of stone 10 feet wide and 10 feet high. Alternatively, he could scan an area 5 feet wide and 20 feet high.
Secret compartments, drawers, recesses, and doors are 90% likely to be located by x-ray vision scanning. Even though this ring enables its wearer to scan secret doors, traps, hidden items, and the like, it also limits his use of the power, for it drains 1 point of Constitution if used more frequently than once every six turns. If it is used three turns in one hour, the user loses 2 points from his total Constitution score, 3 if used four turns, etc.
This Constitution loss is recovered at the rate of 2 points per day of rest. If Constitution reaches 2, the wearer is exhausted and must rest immediately. No activity, not even walking, can be performed until Constitution returns to 3 or better.
