Centurion

Receiving training that allows them to channel their Ki to deliver seismic strikes with their fists and learning the ways of the blade to cut down their foes, the Centurions are masters of martial combat. When a Centurion enters the battlefield, whether they are leading their allies or facing down a mighty foe in 1 on 1 combat, all who know of their legend are the first to back down and those who don't... Well, they soon learn of it. As a mighty warrior from the past once said," The Centurion sees the battlefield like a chessboard. Each warrior has their part to play and sometimes sacrifices need to be made. This is the nature of war and the Centurion revels in it."

Centurion’s Wrath

When you choose this archetype at 3rd level you gain the ability to make an unarmed attack or a grapple as a free action after a successful attack. If the unarmed strike is successful it stuns the opponent until they are attacked, or until the start of their turn. You can only to do this once per round. After 2 uses you will need a short or long rest to regain this ability. The number of uses between rests increases to 3 times at level 10, and 4 times at level 18

Lion’s Claw

At 3rd level your unarmed damage becomes a 1d4. At level 7 this damage increases to a 1d6

Imperial Might

Starting at 7th level your critical hits using unarmed strikes knock your opponent prone unless they make a STR saving throw. (DC = 8 + STR Mod + proficiency bonus)

Against All Odds

At 10th level, when your party is outnumbered two to one, your attacks gain advantage,  your AC increases by 1, and you deal an extra 1d4 points of damage

Predator's Rage

At 15th level, you gain the ability to make a running, jump attack once per short or long rest that causes increased damage. On a hit, they suffer an extra 2d6 points of bleed damage. They must make a STR saving throw or be knocked prone(DC = 8 + STR Mod). The attack is made with disadvantage and provokes an attack of opportunity on a miss. You must have at least 5 ft between you and the victim of your attack. At level 18 you can do this twice.

Revenge

At level 18 if your health is dropped below 15% of your maximum health you may regain a total amount of hit points equal to 4d10 + your CON modifier and for two rounds your AC increases by 2. Revenge can only be used once and adds a point of exhaustion upon the end of the duration. This ability is regained after a long rest.
