Ace Up the Sleeve

While the bearer of Ace Up the Sleeve makes a roll that is part of gambling the bearer may choose to re-roll the die by expending a charge.  The bearer must accept the second roll, even if it was worse than the initial roll,  An observer with a passive perception of 18 or higher will notice that the results of the gambling activity have been magically altered, but not by whom.  The Ace Up the Sleeve has one charge that recharges at dawn.
