Monks of the Way of the Raging Soul are twisted and beastly in nature, using their own claws and fangs to rip their foes apart and rage like the most powerful of barbarians, able to manipulate their Ki to do so.

Soul of Beasthood

Starting when you choose this tradition at 3rd level, you can enter a state that allows you to use your physical strength to hone your dexterity-based attacks to a finer point than they already are. When you hit with a melee attack that uses the Flurry of Blows that utilizes Dexterity, you can add your Strength modifier to the damage. In addition, depending on your current disposition, your unarmed strike can use piercing or slashing damage.

State of Wrath

At 6th level, you gain the ability to use your anger and beastly instinct in a state of rage. As a bonus action on your turn (a number of times equal to your wisdom modifier that recharges after a long rest), you can enter a terrifying state of anger for 1 minute. While in this state, all of your dexterity-based attacks have their strength modifier added to it, and your AC is increased by your Constitution modifier while in this state.

Nature's Brutality

At 11th level, your State of Wrath has improved to become even more powerful. While in your state of Wrath, your unarmed strikes inflict a critical hit on a 19 or 20, and you can roll one extra damage dice when calculating the damage of a critical hit. In addition, while in your State of Wrath, you can choose to attack with reckless abandon, attacking with advantage. However, once your State of Wrath subsides you must make a Constitution Saving Throw or suffer a point of exhaustion. The DC is 10 + the number of times you gave yourself this reckless advantage during the State of Wrath.

Wrath of the Immortal Beast

At 17th level, your State of Wrath lets you resist being knocked unconscious. While in your state of wrath, you have resistance to all nonmagical bludgeoning, piercing, and slashing damage, and when you would be knocked unconscious while in your rage state, you can use your reaction to spend any number of Ki Points and regain 5 HP for every Ki Point spent.
