Path of the Champion

Path of the Champion focuses on the barbarian's ability to rally those around him and take out their opponents with ruthless aggression. 

Sting Like a Bee

At 3rd level, when you chose this subclass, your practice of martial arts gives you a buff, allowing you to add your rage bonus to your unarmed strikes. Your unarmed strikes deal bludgeoning damage equal to 1d8+str instead of the bludgeoning normal for an unarmed strike, in addition when you roll a 19 on the d20 for the attack with your unarmed strikes, you can choose to have the attack be treated as a critical hit, you can critically hit in this way a number of times equal to your proficiency bonus and regain all uses of this feature after completing a long rest.

Your crit range increases by 1 at 10th and 14th level.

Float Like a Butterfly

Starting at 6th level you may use a reaction to take the dodge action.

Additionally when you are taking the dodge action, and get attacked by a creature within melee range of you, you may use your reaction to attack them. This feature can only be used as many times equal to your proficiency modifier.

Keep Moving Forward

Starting at 10th level whenever you are dropped to 0 hit points you may use your reaction to roll a hit die(given you have one left) and add that + your constitution modifier to your hp.  Once you use this feature you will not be able to use it again until you finish a long rest.

Eye of the Tiger

Starting at 14th level when you rage you channel the inner rage of a champion, giving you the following benefits:

-When you use your "Keep Moving Forward" ability you instead remain at 0 hit points. While you’re raging, having 0 hit points doesn’t knock you unconscious. You still must make death saving throws, and you suffer the normal effects of taking damage while at 0 hit points. However, if you would die due to failing death saving throws, you don’t die until your rage ends, and you die then only if you still have 0 hit points.

-You may use your "Float like a Butterfly" ability at will, not being tied to your proficiency modifier.

-If you use your attack action to make unarmed strikes you may use your bonus action to make another unarmed strike. 

 

Underdog

You're a potent athlete but also a fantastic entertainer, you gain proficiency in performance and can use your strength instead of your charisma to make performance checks related to sports. If you already have proficiency in performance, you can instead gain proficiency in another skill of your choice.
