Dark Kitsune

The kitsune has advantage on Wisdom (Perception) checks.

The Kitsune can use its action to transform into a Bat, Cat, Rat, Weasel, or back into its original form. It retains its own skill and saving throw proficiencies, Intelligence, Wisdom, and Charisma ability scores, health, known spells, known companion features, and multiattack in all forms. It uses the other statistics from the form it is currently in. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Melee Attack Roll: [Its Strength or Dexterity modifier + your Proficieny Bonus] to hit, reach 5 ft., one target. Hit: 1d8 + [Its Strength or Dexterity modifier] Piercing damage.

A 10-foot-radius Sphere of magical darkness appears in an area centred on the kitsune. The darkness remains there for 1 minute, or until it is removed by an effect such as Dispel Magic, counting as a 1st level spell.

The Kitsune can use this feature a number of times equal to your Wisdom modifier (minimum of 1). It regains all expended uses when it finishes a Long Rest.
