Shapechanger. You can use an action to polymorph into a Medium Wolf-Humanoid hybrid or into a Medium Wolf, or back into your true form. Your statistics, other than size and AC are the same in each form. Any equipment you are wearing or carrying isn't transformed. You revert back to your true form if you die.

Wolf-Humanoid Hybrid Form. Your size is Medium. You have natural armour equal to 11 + Dexterity Modifier. You gain the Bite attack and are considered proficient: Melee Weapon Attack, one target, 1d8+Strength piercing damage. If the target is a humanoid, it must succeed on a DC 10 + Constitution Modifier, Constitution Saving Throw or be cursed with werewolf lycanthropy. You gain the Claw attack and are considered proficient: Melee Weapon Attack, one target, 2d4+Strength slashing damage.

Wolf Form. Your size is Medium. You have natural armour equal to 11 + Dexterity Modifier. Your walking speed is 40ft. You gain the Bite attack and are considered proficient: Melee Weapon Attack, one target, 1d6+Strength piercing damage. If the target is a humanoid, it must succeed on a DC 10 + Constitution Modifier, Constitution Saving Throw or be cursed with werewolf lycanthropy.

Keen Hearing and Smell. While in your Wolf-Humanoid Hybrid form, or your Wolf form, gain advantage on Wisdom (Perception) checks that rely on hearing or smell.

Starting at 3rd level, you can use your reaction to deflect or catch the missile when you are hit by a ranged weapon attack. When you do so, the damage you take from the attack is reduced by 1d10 + your Dexterity modifier + your monk level. If you reduce the damage to 0, you can catch the missile if it is small enough for you to hold in one hand and you have at least one hand free. If you catch a missile in this way, you can spend 1 ki point to make a ranged attack with a range of 20/60 using the weapon or piece of ammunition you just caught, as part of the same reaction. You make this attack with proficiency, regardless of your weapon proficiencies, and the missile counts as a monk weapon for the attack.

Also at 3rd level, if you spend 1 ki point or more as part of your action on your turn, you can make one attack with an unarmed strike or a monk weapon as a bonus action before the end of the turn
