All Out Brawl

Starting at 5th Level, you can start to get a sense of power, like a power surging within you.

On your turn, you can instantly roll a 20 on your hit dice. Doing this will make you unstable on your next turn. If you get attacked on after the turn All Out Brawl was used, the attacker will have advantage on you and if they hit, you will be prone and if they miss you get level 1 exhaustion
