Mixed Martial Artist

To some, martial arts a spiritual endeavor. You become one with your body and achieve enlightenment. To you, martial arts are a way of life, a physical activity that connects you to the most primal version of you. You trained either as a grappler, getting close to the enemy and forcing them to submit to your holds, or as a striker, forcing your opponent to yield to a barrage of punches and kicks targeted to lay them low. 

Mixed Martial Arts

Beginning when you choose this archetype at 3rd level, you can choose to specialize in either grappling, or striking. As a grappling specialist, you'll gain the ability to grapple and pin your opponents. As a striking specialist, you'll gain the ability to strike harder and more often and move out of the way of incoming attacks. 

Regardless of choice, your unarmed strikes immediately become a d6 plus Strength or Dexterity depending on if you chose Grappler or Striker. At levels 5, 9, and 11, your unarmed strikes increase to a d8, a d10, and finally a d12,  respectively. You also gain expertise in Athletics.

Grappling Expert

You are a expertly trained grappler, and your abilities reflect your training. Once per turn as a bonus action, you can attempt to grapple an enemy. Any checks you make to grapple an enemy, or against an enemy attempting to escape your grapple you add your proficiency bonus twice to. Additionally, enemies grappled by you are considered restrained.

You also gain the ability to use your attack action to Slam an enemy you have grappled once per attack action, inflicting damage, with the potential to Daze your enemy until the beginning of your next turn. Regardless of how many times you Slam an opponent, you may only attempt to Daze them once per turn. Additionally, your AC becomes 10 + Strength Modifier + Proficiency. 

Additionally, you gain double your proficiency amount of Submission Dice, which are a d6 at level 3, a d8 at level 7, a d10 at level 11, and a d12 at level 14, to be used in fueling maneuvers related to your expertise. Those maneuvers are as follows, and can only be used once you have an opponent grappled:

Arm Bar. As part of an attack, you expend a Submission Die to put an opponent in an arm bar while they're restrained, doing bonus damage equal to the amount rolled on your Submission Die, and forcing them to make a Strength saving throw against your save DC or be disarmed. If already disarmed, you damage their arm or limb further, forcing disadvantage on Strength and Dexterity based saving throws and checks until the end of their next turn. 

Sleeper Hold. As part of an attack action, you expend a submission die to attempt to put a restrained opponent to Sleep until the end of their next turn, they take damage, or an ally takes an action to wake them. You deal damage equal to the die rolled, and they make a Constitution saving throw against your save DC or fall asleep and become incapacitated as described. 

Reversal. As a reaction to being hit by a Melee attack, you can expend a Submission Die to roll with the hit, reducing the damage taken by the amount on the die, and attempt to grapple your opponent. 

Striking Expert

You have trained diligently at the ability to strike your opponent just where you need to, or want to, and to use your whole body as a weapon. Not just your fists. As a striker, you're nimble, you're fast. You gain the ability to make a kick attack as a bonus action. As long as you're not wearing a shield or armor, your movement speed is increased by 10ft and your AC is 10 plus your Dexterity modifier and your proficiency bonus. You also gain your proficiency amount of Striker Dice, to be used in maneuvers related to your specific training. Your Striker Dice are a d6 at level 3, then go up to a d8 at 5, a d10 at 9, and a d12 at level 11.

Additionally, once per turn, you can expend a Striker Die to do one of the following:

Targeted Strike: As part of the Attack action, you can expend a Striker Die to add that number to your attack roll, potentially turning a miss into a hit. If the attack hits, the immediate next attack you make has advantage. 

Power Shot: You can expend a Striker Die to add the roll to your damage total, slamming your fist or palm into a vulnerable region. Target must make a Strength save against your Save DC or be knocked prone. 

Sweep the Leg: You can expend a Striker Die on your bonus action Leg Strike attack, forcing the opponent to make a Strength or Dexterity saving throw against your Save DC or be knocked prone.

Elevated Technique

Starting at 7th level, you can impose disadvantage on saving throws and ability checks on the subjects of your various techniques up to proficiency times per day. Your strikes become magical for the sake of bypassing resistances. You can use your reaction to being hit by a spell attack or if you're forced to make a Dexterity or Constitution saving throw by a spell, to burn a Technique die, rolling it and adding your Constitution modifier to the total, reducing the amount of damage taken by that amount. Additionally, Grapplers now can Brace as a bonus action, and Strikers can Disengage as a bonus action. You also gain two new maneuvers for your chosen specialization, detailed below. 

Grappler

Hip Toss. As part of an attack action, you can expend a Submission die on a successful attack against a restrained target to throw them a distance equal to 5ft times the number rolled on the Submission die. The target is knocked prone and takes 1d6 bludgeoning damage for every 10ft it is thrown by this technique. 

Kimura. As part of an attack action on a creature that is restrained by you, you can expend a Submission die and add it to a contested Athletics check with the restrained target. If you beat their check by more than 5, they are incapacitated as though paralyzed and they take damage equal to the difference in your checks. On a successful check, your speed is also reduced to 0 as you hold the creature down. On a failure the creature is released at the end of your turn. 

Brace. As a bonus action, you can Brace, granting yourself resistance to all incoming damage except for force, radiant, necrotic, and psychic damage for one round, but reducing your speed to 0. You cannot move and use this ability in the same turn. 

Striker

Flow Blocker. As part of an attack action that hits, you can expend a Striker die to attempt to break spell concentration, disrupt a magical effect, or block a ki user's ki. The target makes a Constitution saving throw against your Save DC. On a failure, any ongoing spells or magical effects end, and the target can't use magic or ki points until the start of their next turn. 

Feint. As part of an attack action but before you roll your attack, you can expend a Striker die to make a target make a Dexterity Saving throw vs your Sleight of Hand check, adding your Striker die to the check. On a successful check, the attack has advantage and crits on an 17-20. On a failure the die is expended with no benefit. 

In addition, when you make a long jump, high jump, the distance you can cover increases by a number of feet equal to your Strength modifier. You also gain expertise in Acrobatics.
