Way of Claw and Fang
Monks trained under this archetype connect their ki to creatures of the wilds. Through their energy, they bring forth a beast who shares the same mind and soul with you. In combat, you fight as fierce, as swift, as cunning, and as one. As time passes, both you and your companion will grow unstoppable and inseparable, for the distance does not matter, for the ki within each of you keeps you connected.
Animal Companion
- At 3rd level, you learn to use your ki to create a powerful bond with a creature of the natural world. With 8 hours of work and the expenditure of 50 gp worth of rare herbs and fine food, you call forth an animal from the wilderness to serve as your faithful companion. You normally select your companion from among the following animals: an ape, a black bear, a boar, a giant badger, a giant weasel, a mule, a panther, or a wolf. However, your DM might pick one of these animals for you, based on the surrounding terrain and on what types of creatures would logically be present in the area. At the end of the 8 hours, your animal companion appears. You can have only one animal companion at a time. If your animal companion is ever slain, the spiritual bond you share allows you to return it to life. With 8 hours of work and the expenditure of 25 gp worth of rare herbs and fine food, you call forth your companion's spirit and can use your ki to create a new body for it. You can return an animal companion to life in this manner even if you do not possess any part of its body. If you use this ability to return a former animal companion to life while you have a current animal companion, your current companion leaves you and is replaced by the restored companion.
- Your animal companion has abilities and game statistics determined in part by your level. Your companion uses your proficiency bonus rather than its own. In addition to the areas where it normally uses its proficiency bonus, an animal companion also adds its proficiency bonus to its AC and to its damage rolls.
- Your animal companion gains proficiency in two skills of your choice. It also becomes proficient with all saving throws.
- For each level you gain after 3rd, your animal companion gains an additional hit die and increases its hit points accordingly. Whenever you gain the Ability Score Improvement class feature, your companion’s abilities also improve. Your companion can increase one ability score of your choice by 2, or it can increase two ability scores of your choice by 1. As normal, your companion can’t increase an ability score above 20 using this feature unless its description specifies otherwise.
- Your companion will roll initiative like everyone else and will take their own turn in combat. If you don't order it to do anything, it will act on its own trying it's best to protect you or itself.
- Your companion gains an Unarmored Movement equal to yours.
- Your companions DC for its abilities is 8+ your proficiency mod + your companion's Strength or Dex mod
- Your companion makes death saving throws like everyone else.
Companion Ki
Your companion's ki will be your max ki halved (rounded down) And they gain the following abilities:
Lunging Leap
Your companion can spend 1 ki point to triple their jump height and length, lunging at an enemy they can reach. The creature must make a Strength saving throw or be knocked prone, this only works on creatures of Large or smaller size. If the creature is to be knocked prone from the this, the companion can make a free extra attack.
Of the Same Mind
Immediately after you take the Attack action, your companion can spend 1 ki point to make a reactionary strike. This uses up its reaction if it hasn't already used it.
Call of the Wild
Your companion can spend up to 1 ki points to cry out to all his allies. Every friendly creature within 30ft of your companion may take one of two benefits: Temp HP equal to your Martial Arts Die + your companion's Wisdom modifier, or advantage on their next attack roll. This ability, however, leaves your companion open, giving advantage on all rolls to hit it until the start of its next turn.
In Spirit
At 6th level, you and your companion are not only of the same mind, but the soul as well. Your companion's attacks are now magical for the purpose of overcoming resistances and immunities. Whenever your companion would go down in battle, you can take one of his Companion Ki features abilities and use it once per encounter until they regain hit points, or until they are brought back to life.
Camaraderie Grows

Pack Leader
