Blissful Ignorance

Ability Score Increase. Increase your Dexterity, Constitution, Intelligence, Wisdom, or Charisma score by 1, to a maximum of 20.

Dumb Luck. As a reaction, after you or a creature you can see within 30 feet of you makes an attack roll, an ability check, or a saving throw, you can force the creature to reroll. You make this decision after you see whether the roll succeeds or fails. You can choose which one to use. You can use this ability twice, and you regain any expended uses when you finish a long rest.
