You’re gradually getting tougher as you progress up the scales of being a bruising basher. You start to shrug off hits easier. As an action, you can hype yourself up with a rudimentary gesture. This can be anything from slapping yourself on the cheeks, or screaming that you can beat whomever you’re fighting. Regardless, this action will give you Temporary HP equal to four times the amount of Grit Points you spend on it, the max amount you can spend being equal to your tier. You may use this feature 3 times per day.
Additionally, you start to get lighter on your feet. You gain proficiency in Acrobatics, and gain expertise if already proficient in it. And you can add 10 feet to your movement speed, and can Dash as a bonus action on your turn.
You gain some Dirty Fighting Techniques when you choose this feature. These are added to the list of Dirty Fighting Techniques you can use.

Extended Attack
