Veteran

The Veteran subclass hones in on a Fighter's fighting ability and provides addition damage and benefits to keep them in the fight longer. This build takes the UA Brute as its base and changes it slightly to focus in on damage and survivability, all while attempting to maintain its simplistic design to provide players with an option other than Champion. The Brute was seen more in lines of Strength based however, the Veteran subclass' verbiage keeps in mind for both Strength and Dexterity builds. 

Conditioned Strike

Starting at 3rd level, you've trained your body to strike with devastating or calculated force. Whenever you hit with a melee attack, the damage increases by an amount based on your level in this class starting at 1d4 at 3rd level, increasing to 1d6 at 5th, 1d8 at 11th, and finally 1d10 at 17th.

Conditioned Body

Starting at 3rd level, you've conditioned your body to take excess punishment, when you gain this feature your hit points increase by 3 and continue to increase by 1 for every level afterwards in this class.

Determination of One's Will

Starting at 7th level, your training allows you to shrug off assaults that would devastate others. Whenever you make a saving throw, roll 1d6 and add the results to your saving throw total. If applying this bonus to a death saving throw increases the total to 20 or higher, you gain the benefits of rolling a 20 on a d20.

Inspiring Rally

Starting at 10th level, when you use your Action Surge feature, you and your allies within 30ft of you gain advantage on their attacks until the start of your next turn.

Evening the Odds

Starting at 15th level, when you score a critical hit with a melee attack, you gain a bonus to the damage equal to your level in this class.

Dominion Of One

Starting at 18th level, you have reached the pinnacle of your training, as an action you cultivate all of your battle knowledge and enter a state of extraordinary prowess, gaining the following benefits for 1 minute.

• You have resistance to all damage.
• Your movement speed is doubled.
• When you take the Attack action on your turn, you can make one additional attack as part of the action.
• You regain hit points at the start of your turn equal to 5 + your Constitution modifier (minimum of 1). You don't gain this benefit if you have 0 hit points or if you have more than half of your hit points left.

As result of extending ones self to their limits your movement speed becomes 0ft until the start of your next turn and you gain one level of Exhaustion. You can continue to use this feature but continue to accumulate levels of Exhaustion with each use.
