Your experience, skills, or just gut feelings have helped you see situations coming before they showed up. You have developed a way to predict the future to a minor degree. When you finish a long rest, roll two d6s and record the numbers rolled. You can add or subtract to any attack roll, saving throw, or ability check made by you or a creature that you can see with one of these foretelling rolls. You must choose to do so before the roll, and you can replace a roll in this way only once per turn. Each foretelling roll can be used only once. When you finish a long rest, you lose any unused foretelling rolls.
