Thunder Kitsune

The kitsune has advantage on Wisdom (Perception) checks.

The Kitsune can use its action to transform into a Cat, Lizard, Metal Wand, 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: 1d6 + [Its Strength or Dexterity modifier] Piercing damage and 1d4 Lightning damage.

The fur of the kitsune shoots out sparks of lightning. Dexterity Saving Throw: DC 8 + [Its Intelligence, Wisdom, or Charisma modifier (your choice) + your Proficiency Bonus], each creature in a 10-foot-radius Emanation, originating from the kitsune. Failure: Lightning damage equal to an amount of d8s equal to your proficiency bonus. Success: Half damage.

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.
