Your age depends on the race you were born as, although most Lycanthropes don't live to be old

Focusing more on survival than anything else, Lycanborns tend to lean more towards chaotic neutral than to bother with concepts of good and evil and rules and laws. But exceptions exist, as they do in all races.

Your size is medium, your height and weight coincide with the race you were born as.

Your base walking speed is 30 feet.

You have superior vision in dark and dim conditions. You can see in dim light withing 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern colour in darkness, only shades of gray.

Due to being born as a Lycanthrope you've gained some bestial traits, even when not shapeshifted.

You gain proficiency in the Athletics and Survival skills and you have advantage on any Perception (Wisdom) check you make relying on hearing or smell.

Your curse forces you to take the form of a Direwolf every full moon, most Lycanthropes lose control when this happens, but to Lycanborn this form is as natural their other, allowing them to keep their mind. 

Starting at 3rd level you are able to willingly take the form of a Direwolf, you're able to use this ability an amount of time equal to half your proficiency modifier (rounded up) per long rest for an amount of time equal to your total level. While in this form your game statistics are replaces by the statistics of the Direwolf, but you retain your alignment, personality, and Intelligence, Wisdom and Charisma scores. You also retain all of your skill and saving throw proficiencies. If you have the Extra attack feature you keep it, when making an attack in this form you can use your proficiency modifier for the attack roll. In addition you gain resistance to nonmagical weapon attacks that aren't silvered.
