Gladiator

The Gladiator
Rawr! You combine the fury of a barbarian with the controlled demolition of a fighter. You hit hard, and when things hit you, you hit back harder.

Double Up
You're a little reckless, but that's what the crowd loves about you! At level 8 you can take a bonus action to Psyche Up, but you grant advantage to all enemies attacking you.

Feel The Burn
A little bump on the head never hurt anyone. Well, maybe that one guy. But he's a pansy. At level 13, as a reaction, you can Psyche Up in response to being hit by an attack.

Blind Man's Biff
The glory of the gladiator is occasionally just flooring a sucker with one punch or smash or whatever you guys do. At 18th level, once per turn, you can take disadvantage on a weapon attack you make. If you hit with this attack, the attack is a critical hit.
