A pair of matching silver cufflinks, each inscribed with the letter W and the image of a die. The cufflinks are possessed by the spirit of Wynd, an infamous cardshark who is still said to haunt the halls of Isla Fortuna. 

As a bonus action, while playing a game of dice or cards, the wearer may invoke the spirit of Wynd. He will tell them their opponent's secret dice rolls or hand of cards.

The cufflinks have 5 uses before the Wynd's spirit gets bored and heads to the afterlife.
