On a full moon you fully transform into a Zombie werewolf jumping your Strength up to 15 (if it isnt already) as well as a +1 in your AC, you also get the multi attack ability with your claws and bite you also gain immunity too  bludgeoning, piercing, and slashing damage from nonmagical attacks but becomes vulnerable to silvered weapons. you also become large

On a cloudy full you moon you might experience going into a rage (your hybrid state) this state is in between human and werewolf. if this is the case roll a DC 13 Wis saving throw if you fail the check you become your hybrid state, make a DC 13 Charisma saving throw  too see if you can keep control of this side. if you fail you loose control and have to use all of your movement to get to the nearest creature and attack it, the saving throw can be repeated but the Dc goes up by 1 for each time

In your full transformation you gain 15 more walking speed as you become more agile then your human form

In your hybrid state you gain 10 more walking speed as you struggle with the other side of you
