Juan Pounce de Leon's Chalice

Origin
Ponce de Leon was a Spanish explorer and conquistador of the New World who famously searched Florida for the waters of the Fountain of Youth.

Effects
This silver with gold lining cup was imbued with his obsession for finding eternal youth. When water is poured into the chalice, the water is giving age reversing effects. One full cup can age a person back ten years. The cup will only work with pure fresh water. If any other type of liquid is used will give the exact opposite effects.
