Spartan Warrior

Spartans are the most enduring soldiers imaginable. They exist to fight, however they live by a strict code of honor: no soldier is superior to another, a calm mind is stronger than a reckless one; and they never, ever, drop their shield. You will fight to your last breath, but you will not put those around you in unnecessary danger. Others look at you and think of you as a brute, but what they don't see is the brilliant tactician that lives within you. You are not a Barbarian; you are a Fighter and a warrior. You strike with precision without giving the enemy an easy strike against you.

Empowered Piercing

At 3rd level your mastery with melee piecing weapons and shields allows your peircing strikes to get stronger and accurate.
Whenever you hit a enemy with a melee weapon that deals piercing damage you can add bonus damage to the attack equal to your shield AC bonus.

Piercing Defender

At 7th level, your training with shield and piercing weapons grants you  the following features:

The range for piercing melee wepons that have the "Thrown" property increases by 20ft for both short and long range (Does not increase the melee range).

When a enemy misses an attack agaisnt you, you can use your shield to bash them away making them roll a Strength saving throw or be pushed 10ft away from you. DC is 8 + profiencicy bonus + your Strength modifier. You must be wielding a shield to use this reaction.

Undaunted Will

After 10th level, your years of fighting grant you a fearlessness to death. You are immune to the frightened condition.

Last Stand

Starting at 15th level, you are braver than most; never allowing yourself to retreat in battle. When you fall below half of your maximum hit points, you gain a number of temporary hit points. The total of these hit points equal your Fighter level.
While you have temporary hit points granted to you by this feature, you have advantage on melee attack rolls.

Once you use this trait, you cannot use it again until you finish a long rest, or if you roll a natural 20 on a death saving throw.

Bred for Battle

At 18th level, your expertise in battle has granted you stamina beyond any other warrior. You gain one additional use of your Action Surge. Additionally, while wielding a weapon with the "versatile" property, you may now use the higher damage die of that weapon whilst holding it in one hand. This feature only functions while a shield is equipped.

This feature cannot be activated more than once per turn
