Way of the Beast

Monks martial arts styles take on many forms, from open palm strikes and quick flurries, to magical blasts of energy. However, one of the most ancient and true forms of martial arts are the animal styles; crane, snake, hawk, and many other styles all exist to emulate nature, and increase lethality via the wisdom of evolution. 

Nature's Disciple

3rd-Level Way of the Beast Feature

You learn the secrets of the large beasts to eat well and deliver powerful attacks with your fists. At 1st level, your hit point maximum increases by 2 and increases by 2 again whenever you gain a level. In addition, your unarmed strikes count as natural weapon attacks. 

However, in order to maintain yourself, you need  to eat more food, to accommodate your powerful frame. When you take a rest, you gain a level of exhausting after that rest, unless you eat double the usual portion for your size during that time. However, if you do, you gain temporary hit points equal to twice your level until your next rest.

 

 

Stalking Strikes

3rd-Level Way of the Beast Feature

You learn the secrets of the great predators of the wilds; the multiattack. When you take the attack or flurry of blows bonus action, you can instead use the multiattack action, which makes 2 natural weapon attacks. You can also now choose to do slashing or piercing damage with your unarmed attacks, instead of only bludgeoning damage. You can now ready bonus actions, as if you took the readied action. If you ready both an action and bonus action, you do not need to use a reaction for either to resolve their effects.

 

Floating Technique

6th-Level Way of the Beast Feature

You have extensively studied the techniques of flying creatures and their hunting styles, adapting them to your own. Your vision improves, allowing you to see up to 5 miles unaided without a lens, and spot things as small as one inch across with frightening accuracy. Your may add your dexterity modifier to perception checks. As long as you are conscious, if your passive perception is higher than a creature's active stealth roll (automatically passing if they do not attempt to hide from you), you cannot have disadvantage on attacks made against them, and they cannot have advantage on attacks made against you. 

Aspect of the Wild

11th-Level Way of the Beast Feature

The power of the wilds is now interred in your body,  allowing you to take on your truest form. As a bonus action you may spend 3 Ki to take on the visage of a beast or wendigo, though your humanlike posture does not change. While in this form, you may spend a ki at any time to expend a hit die, healing for that amount. Once per visage form, if you start your turn bloodied, you may enrage; you double all healing you receive, and you deal one additional die of damage with natural weapon attacks. This form ends when you hits zero hit points, or after one hour.

King of the Jungle

17th-Level Way of the Beast Feature 

You have become a master of the beast fighting style, equal parts tough, lethal, and cunning. As the king of the jungle, natural weapon attacks, and unarmed strikes against you gain a penalty to hit, equal to half your monk level, rounded down. You are immune to fall damage, and to non-magical slashing, piercing and bludgeoning damage. Your speed cannot be impacted by difficult terrain, and mundane environmental effects, poisons, traps and effects have no effect on you. 

In addition, your ability to hide from prying eyes is mastered, allowing you to live in peace from poachers, tourists, and pesky curious adventurers in your natural environment. Images of you of any kind except by direct sight are dark and blurry, impossible to make out, even if something as simple as glass obscures your form. Creatures who see you this way can tell your general direction, as if you were Invisible to them.
