Foresight
You start to see omens everywhere you look. After a long rest, roll two d20s and record those rolls as your two foresight rolls.
When you or a creature you can see is about to make an attack roll, saving throw, or ability check, you can expend one of your foresight rolls to use that number, once per turn. After a long rest, you lose and reroll your foresight rolls. At level 10, you gain another foresight roll, for a total of 3.
