You’ve learned to control the lycanthropic curse that courses through your veins. As a bonus action, you can assume one of two bestial forms. This transformation lasts for 10 minutes, until you die, or until you revert to your normal appearance as a bonus action. When you change, you gain temporary hit points equal to your character level + your Constitution modifier (minimum of 1 temporary hit point). You also gain additional benefits depending on your chosen bestial form, described below. Once you transform, you can't do so again until you finish a short or long rest.

Your character can speak, read, and write Common and one other language that you and your DM agree is appropriate for the character.
