Soul of the Unrelenting

General Feat

Your experience fighting unarmed has taught you to ignore pain for the sake of landing as many strikes as possible.

Sturdier Frame. Increase your hp by your con modifier + proficiency bonus, at level 17 you no longer add your proficiency bonus, instead the additional hit points now equals your constitution score.

Adrenaline Rush. Over the course of your pugilistic career, you gain new ways to shrug off and deal more damage. Once per turn, you can deal additional damage of the same type as your unarmed strike. You gain temporary hit points equal to half of the damage dealt by this feature rounded down.

The dice increases as the character grows; Levels 1-4(1d4), 5-8 (1d6), 9-12 (1d8), 13-16 (1d10), 17-20(1d12)
