Lycanthrope

 To determine your lycanthrope strain you can roll or pick from the lycanthrope table below.

Shapechanger. You can use an action to polymorph into a Beast-Humanoid Hybrid or into true beast form, or back into your true form. When in your hybrid form, all your statistics remain the same and you revert back to your true form if you die. You can speak, use equipment, and wear armor while in this form. You gain temporary hit points = Proficiency + Constitution Modifier. You are vulnerable to Piercing, Bludgeoning and Slashing attacks made with silvered weapons. 

Frenzy. When in your Beast-Humanoid Hybrid you must succeed on a DC 8 Wisdom saving throw or move directly toward the nearest creature and use the Attack action against that creature. Once your attack is resolved, you regain control of yourself and may continue your turn as normal.

If you have your Extra Attack feature, you can choose whether to use it for this frenzied attack. If more than one creature is equally near to you, roll randomly to determine your target. 

Bite Attack. You gain the Bite attack and are considered proficient: Melee Weapon Attack, one target, 1d6 + Strength/Dexterity Modifier piercing damage.
