Nothing to Lose

Ability Score Increase. Increase your Strength, Dexterity, or Constitution score by 1, to a maximum of 20.

Reckless Strike. As a Bonus Action, you enter a reckless frenzy. Until the end of your current turn, every time you successfully hit a creature with a melee weapon attack, your bonus to melee weapon damage rolls for subsequent attacks increases by 1d6 (e.g., your second hit deals +1d6, your third deals +2d6). However, if you miss an attack while in this frenzy, your momentum shatters: your turn immediately ends, and attack rolls against you have Advantage until the start of your next turn. You can use this Bonus Action a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Long Rest.
