You turn it over in your hands, and discover it has writing on the back. Its etched in, very finely, and around the letters are patterns and symbols you don't recognize. It reads
“If a person puts the chain around his neck and touches an article of
clothing to a Medallion, he will transform into a duplicate of the last
person to wear that clothing as he or she was at the time the article of
clothing was worn. If the clothing had never been worn, the person will
transform into someone who could wear such an article of clothing.
Partial transformations are possible. For example, a slender person who put
on the clothing of a heavier person would gain the weight necessary to wear
the garments. By this means, gender transformations, rejuvenation or aging,
and rapid healing are all possible. The latter is accomplished by having
the injured person done a garment worn before the injury occurred.
If two persons grasp the Medallion at the same time, they will transform
into each other. This power has made the Medallions highly valued for
espionage purposes through the ages.”
After reading it over a few times you begin to understand. "So if I touch any clothing or person with this ill look like them. Hmmm." You say to yourself.
A wide grin comes across your face as you head to your car with a devious idea in mind."
