Lucky Ring of the Wild Coast

This magical ring was originally created by a wizard who liked to gamble, and quickly it became a common tool for any gambler of the Wild Coast. When you wear this magic ring, you gain advantage on any Dexterity (Sleight of Hand) check that you make in order to gamble at a game you are playing. After you made the check, roll a d20. On a 1, the ring magically glows, revealing its magic to each creature that can see you within 20 feet.
