The beasts that plague men are your prey. Lycans, shapeshifters, eldricth monstrosities and other vile entities all feel the bite of your blade, and feel fear in your presence. The moon is high, and morning does not seem to be coming soon. Let their viscera rain upon you, and may the good blood guide your way.

You may also possibly craft them if your DM permits.

The DC for this is 10+1/2 the level of the attacking creature, or 1/2 it's CR if it has no levels. A natural 20 on the Dexterity(acrobatics) check makes the attacking creature miss automatically. 

Beast Form

Starting at level 18, you gain the ability to shift your form to become more beast like as an action. Your strength becomes 23 if it isn't already higher, and your charisma becomes 5 while in this form. Your speed is increased by 20 ft. and you gain resistance to all bludgeoning, piercing, and slashing attacks from non-magical weapons, but you have vulnerability to silvered weapons. It lasts for 10 minutes or until you end it early as a bonus action. Also, while in this form, you have claws that count as natural weapons. They do 2d6 + 6 slashing damage, and use  STR. 

If you reduce a creature to 0 hit points and kill it, then you may use your reaction to consume a piece of that creature. If you do this, then you regain 2d10 + CON hit points. Whenever you regain hit points this way, you must make a DC 10 WIS saving throw. On a failed save you enter a frenzied state,. In a frenzied state, you must use your action each round to attack the creature nearest to you. If you can make extra attacks as part of the Attack action, you use those extra attacks, moving to attack the next nearest creature after you fell your current target. If you have multiple possible targets, you attack one at random. You are frenzied until you start your turn with no creatures within 60 feet of you that you can see or hear, or you succeed a DC 21 WIS saving throw. Both DCs increase by five each time you regain hit points this way.
