Déjà Vu

Once per long rest you may cast Déjà Vu as a bonus action, causing you to be able to either repeat your previous action exactly as it occurred (an attack action that hit for a certain amount will grant a guaranteed hit for the same amount) or cast it on another creature. Allies will repeat their previous action instantly, enemies must roll a wisdom saving throw or be stunned until the end of your next turn and take 2d6 psychic dmg or half as much on a save.
