Therianthrope

Features
- Hybrid Form
You can shift between your ordinary form and a Hybrid Form that walks upright with your beast's head, hide, and claws. As an action, you can enter your Hybrid Form for up to 10 minutes, and you can leave it early as an action. Your equipment does not change with you. You can enter it a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest. While in Hybrid Form, you have advantage on Strength checks, your unarmed strikes deal 1d6 slashing damage, and you have resistance to bludgeoning, piercing, and slashing damage from nonmagical weapons that are not silvered.
- Silvered Harm
Silver wounds you in any form, and a wound from a silvered weapon knits slowly. You have vulnerability to damage from silvered weapons, and hit points you lose to one are not restored by anything short of a long rest.
- Beast Constitution
The curse hardens the body. You have advantage on saving throws against disease, and you have resistance to poison damage.
- No Tongue of Their Own
A carrier keeps the language of the people the curse took, and Therianthropes have no tongue of their own. You can read, write, and speak Common.
