Favored Foe

When you hit a creature with an attack roll, you
can call on your mystical bond with nature to
mark the target as your favored enemy for 1
minute or until you lose your concentration
(as if you were concentrating on a spell).
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 1d6.
You can use this feature 4 times and you regain
all expended uses when you finish a long rest.
