Often a smooth, polished stone small enough to fit in one’s pocket, these talismans may also take the form of small toys, beaded bracelets, or rings a half-size too loose. When you rub, fidget, or fiddle with this talisman for one minute during a Short or Long Rest, you can reroll an Intelligence check or a Wisdom (Insight) check that you made since the end of your last Short or Long Rest, even if the subject of the check is no longer at hand, and add 1d4 to the total. A given check can only be rerolled with the Worry Stone once.
