Werewolves age at the same rate as their original and/or parent race.

Werewolves tend toward Chaotic alignments when the cures has more power over them, and toward lawful alignments when they have more control over their curse.

Werewolves in their humanoid form maintain the size of their original race. While in their wolf or hybrid form, they are often larger and more imposing, typically standing between 7 and 9 feet tall and weighing around 200 pounds. Your size is medium when in your hybrid or wolf forms.

Your base walking speed is 30 feet. In your wolf form your speed increases to 40 feet, and in your hybrid form, your speed increases to 35 feet.

Your character can speak, read, and write Common and one other language that you and your DM agree is appropriate for your character. If you are replacing your race with a lineage, you retain any languages you had and gain no new languages.

If you replace a race with this lineage, you can keep the following elements of that race: any skill proficiencies you gained from it and any climbing, flying, or swimming speed you gained from it.
If you don’t keep any of those elements or you choose this lineage at character creation, you gain proficiency in two skills of your choice.

The curse of Lycanthropy sharpens your senses, granting you darkvision. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You have advantage on saving throws against being frightened. Additionally, you have resistance to bludgeoning, piercing, and slashing damage from non-magical attacks that aren’t silvered.

As a Bonus action, you can transform into a wolf or hybrid form, or back into your humanoid form. Your statistics are the same in each form, with the exception of your speed as well as some stat changes as listed below and your unarmed strikes are considered magical attacks to ignore immunities and resistances. You revert to your humanoid form if you die.

• Humanoid form. Your stats remain the same. your speed is 30 feet.
• Hybrid form. Your strength Score increases by 1, your intelligence decreases by 1, your speed is 35 feet while in your hybrid form, and you become naturally acclimated to cold climates, even if you’ve never been to one.
• Wolf form. Your Dexterity Score increase by 1, your intelligence score decreases by 1, your speed is 40 feet while in your wolf form, and you become naturally acclimated to cold climates, even if you’ve never been to one. Your Creature Type becomes Beast. Any equipment on your person fall to the ground at your feet, and you are unable to use weapons and/or equipment that are not made for wolves.

You have advantage on Wisdom (Perception) checks that rely on hearing or smell.

In your wolf or hybrid form, you can use your fangs to make an unarmed strike as a bonus action. You are proficient in this unarmed attack, and add either your strength or your dexterity modifier to the attack roll. If you hit with your bite, you deal piercing damage equal to 1d6 + your Strength or dexterity modifier.

The physical and mental toll of transformation can leave you weakened, reflecting the strain it puts on your body and psyche. After you revert from your wolf or hybrid form to your humanoid form, you must succeed on a DC 8 Constitution saving throw or suffer one level of exhaustion. Additionally, on each night of a full moon at midnight, you must succeed on a DC 20 Wisdom saving throw or be forcibly transformed into your wolf form for 8 hours. During this period, you lose control of your character, who acts wildly, attacking every creature in sight and embarking on a frenetic hunt. After this involuntary transformation ends, you suffer a level of exhaustion.
