Skipstone

Wondrous item, rare

This small bark-colored stone measures 3/4 of an inch in diameter and weighs an ounce. You can use an action to throw it up to 60 feet. The first creature struck by, or that physically touches, the stone within the next 1d4 rounds must succeed a DC 15 Constitution saving throw or be thrown forward 1 round in time. The creature disappears, during which time it cannot act or be acted upon in any way. When the creature returns, it is unaware that any time has passed. After the stone is used, it crumbles to dust.
