Path of the Limit Break*

Each living creature is subjected to limits which simply cannot exceeded. Or at least, that's what you've been told. Pushing yourself to the absolute limits of what is possible by sheer will and hard work is what drives you along your path. Relying on magic, armor, weapons, you'll never understand how others can call themselves warriors when they depend on tools such as these to survive in battle. You will forever push yourself, never satisfied until you have cracked through the ceiling hanging about you. And then the next one, and the next one!

Unarmed Combatant

Your whole life you have devoted yourself to battle in its purest form, hand to hand combat. Starting when you choose this path at 3rd level, you abandon the trivial weapons of metal and magic that your allies and enemies so desperately cling to, instead opting to use your flesh and bone to lead you to victory in your battles. You gain the following benefits:

• You can roll a d4 in place of the normal damage of your unarmed strike. This die changes as you gain barbarian levels, 1d6 at 5th level, 1d8 at 11th level, and 1d10 at 17th level.
• When you use the Attack action with an unarmed strike on your turn, you can make one unarmed strike as a bonus action.
• Rage damage is included so long as you use strength as your stat for the attack

Ultra Jump

You never skip leg day.

At 6th level Your vertical leap increases to a height equal to your strength score and your long jump distance increases to a distance equal to 2 times your strength score if you move at least 10 feet on foot immediately before the jump. If you make a standing jump this height or length are halved respectively.

Unleash Restraints

You can take a hit. And when things are looking dire you come back swinging because like they say, What doesn't kill you only makes you stronger. 

At 10th level When you are reduced to half your Hit point total or fewer, you gain a +1 bonus to attack and damage rolls. If you regain hit points back above the threshold this bonus goes away.

This bonus increases as you gain barbarian levels, to +2 at 14th level, and +3 at 18th level.

Unstoppable Force

When you reach 14th level, your momentum when raging becomes a force to be reckoned with. 

While you are raging and if you move 20ft or more in a single direction and hit with an unarmed strike, you deal damage as normal and if the target is a creature you can force the target to make a strength saving throw. On a failure the target is pushed back a number of feet equal to 5 + your strength modifier and knocked prone. If the target succeeds they are not pushed back or knocked prone. You can use this ability once per turn.

The DC for this ability is equal to 8 + your proficiency bonus + your Strength modifier
