Ah yes, the wretched werehyena. I have nothing but hatred for this foul phenotype. These are creatures so enraptured by the evil which resides within their curse that there is rarely a chance of saving them. At least, I have yet to encounter more than a handful of individuals afflicted with this phenotype whom I have found not only approachable, but receptive to the Ritual of Cleansing. I have found it better to simply remove these creatures as I discover them, lest their kind fester and multiply into a cacophony of grisly howls and bloodied fangs, hungry for the flesh of the innocent. -VR

Your statistics, other than your size and AC, are the same in each form. Any equipment you are wearing or carrying isn't transformed. Your movement speed in hyena or Hybrid form is 40 ft., and you gain a 30 ft. climbing speed. You revert to your true form if you die. Your AC is the same in Hybrid form as your Humanoid form but in full hyena form is 13+dex. You can still use weapons in Hybrid form. 
• Pack Tactics. The werehyena has advantage on an attack roll against a creature if at least one of the hyena's allies is within 5 feet of the creature and the ally isn't incapacitated.

• Natural Weapons. You gain two natural weapons which can only be used in your hyena or Hybrid form; a Bite and Claw attack.  Your bite attack deals 2d8 piercing damage. Your claw attack deals 2d6 slashing damage. You may add your strength modifier to these attacks. 
• Multiattack. You can make two claw attacks.
