Daredevil

Daredevils are brawlers who fight with complete abandon. However, while they may look unprofessional and unrefined from an outside perspective, a daredevil is defined by the purpose for which they fight, be it personal glory, a greater calling, or their friends. Few enemies make for scarier opponents than a daredevil brawler with nothing to lose.

Power Strike

Starting at 3rd level, when you make an unarmed strike as part of the Attack action, you can choose not to add your proficiency bonus to the attack roll. If the attack hits, you gain a bonus to the damage roll equal to twice your proficiency bonus.

Tireless Persistence

Starting at 6th level, your persistence in a fight and unwillingness to give up makes you extremely tough. If you hit a creature with an unarmed strike or a brawler weapon on your turn, you gain a number of temporary hit points equal to your Wisdom modifier (minimum of one), which last until the end of your next turn.

Insurmountable Spirit

At 11th level, you cannot be brought down while your spirit is still burning bright. When you are brought to 0 hit points, you can expend 2 spirit points to remain conscious and take actions as normal. You do not need to make death saving throws in this state. Each time you take damage while in this state, or if you start your turn with 0 hit points, you must expend 2 spirit points or immediately fall unconscious. This state ends when you regain any hit points, and once it ends you cannot enter it again until you finish a long rest.

Finishing Blow

 

At 17th level, you can wager all your might and willpower into a single, devastating strike. When you hit with an unarmed strike, you can expend a number of spirit points up to half your brawler level (rounded up). For each spirit point you spend, you add one additional brawler die to the damage. If you spend five or more spirit points, you additionally add your brawler level to the amount of damage done.
