You are driven by a reckless willpower to achieve victory in battle no matter the cost- even going as far as to sacrifice your own vitality to abuse adrenaline.

As a bonus action, you may sacrifice a number of hit points equal to the highest number on your hit die. When you do so, you gain the following benefits until the start of your next turn:

• The first melee weapon attack you make on your turn has advantage.

• Whenever you would successfully hit a creature with a melee weapon attack, you may add an additional damage die equal to your hit die to the roll.

• On a critical hit, you regain a number of hit points equal to your Constitution modifier.

You can use this feature a number of times equal to your Constitution modifier, and regain all uses on a short or long rest.
