Fighter: Battle Champion

A Battle Champion focuses on the development of martial prowess in a relentless pursuit of victory. Battle Champions combine rigorous training with physical excellence to deal devastating blows, withstand peril, and garner glory. Whether in athletic contests or bloody battle, Battle Champions strive for the crown of the victor.
Note: The Battle Champion replaces both the Battlemaster and the Champion. Many of the Battlemaster Features have been rolled into the Maneuver system that all classes can access.

Combat Superiority

Beginning when you choose this archetype at 3rd level, your weapon attacks score a critical hit on a roll of 19 or 20.
Additionally, you are adept at Martial Maneuvers. You add your proficiency bonus to your Martial Levels when determining the number of Superiority Dice, Superiority Dice Value, Maneuvers known, and the types of Maneuvers you can access.

Remarkable Athlete

Starting at 7th level, thanks to your athleticism, you have Advantage on Initiative rolls and Strength (Athletics) checks. In addition, when you make a running long jump, the distance you can cover increases by anumber of feet equal to your Strength modifier.
When you expend a Superiority Dice against a creature and it succeeds on the Saving Throw against your Maneuver DC, you regain that use of the Superiority Dice. You can benefit from this feature once on each of your turns.

Heroic Warrior

At 10th level, the thrill of battle drives you toward victory. During combat, you can give yourself Heroic Advantage whenever you start your turn without it. Additionally, you can choose a second option from the Fighting Style class feature.

Combat Mastery

Starting at 15th level, your weapon attacks score a critical hit on a roll of 18-20.

Survivor

At 18th level, you gain the following features:
Defy Death. You have Advantage on death saving throws. Moreover, when you roll 18–20 on a death save, you gain the benefit of rolling a 20 on a death save.
Heroic Rally. At the start of each of your turns, you regain Hit Points equal to 5 + your Constitution modifier if you have no more than half your Hit Points remaining. You don’t gain this benefit if you have 0 Hit Points.
