Favored Foe

When you hit a creature with an attack roll and
mark the target as your favored enemy for 1
minute or until you lose your concentration.
The first time on each of your turns that you hit
the favored enemy and deal damage to it
including when you mark it, you increase that
damage by 1d4.
You can use this feature to mark a favored enemy
twice and you regain all expended uses when you finish a long rest.
