Second Chance

A pocketwatch that keeps perfect time is always a useful bit of kit. Socketed on any clothing or armor, this specimen is even more special, allowing its user a second chance to perform some action. As a bonus action, immediately before you make an ability check or attack roll, you can activate the stopwatch, setting a call-back marker. After you make the ability check or attack roll (and after you know the outcome), you can choose to rewind time by a few seconds to the moment you took the bonus action (no action required). You must then reroll the ability check or attack roll and use the new result. Whether or not you choose to rewind to the callback marker, after you use this property, it can't be used again until the next dawn.
