Legendary Blade

Throughout legends of old and new, legends emerge of Fighters who achieve remarkable capabilities within combat and strike with unerring accuracy. They swear to train and perfect their skills almost endlessly through rigorous training and practice. Ferocious on the frontlines, Legendary Blades will slice their way through even the largest of hordes, one cut at a time.

Weapon of Choice

When you choose this subclass at 3rd level, you swear an oath to perfect your skills within the martial fighting style of one weapon of your choice. At the end of a long rest, you may spend a minute to choose any melee weapon that is currently in your inventory to dedicate as your weapon of choice. You add +1 to all attack and damage rolls made with this weapon. You may only have 1 weapon in your inventory as your Weapon of Choice at a time.

Unnerving Accuracy

When you reach 3rd level, you begin to master your techniques in a way to perfect your accuracy with unnerving precision. Whenever you use the Fighter's action surge feature, you add twice your proficiency modifier to attack rolls made during your turn instead of your normal proficiency modifier.

Consistent Technique

At 7th level, you have trained and mastered your technique enough with your Weapon of Choice to ensure you maintain consistently devastating effects of your strikes. When you roll damage dice dealt with an attack made by your Weapon of Choice, you may reroll any number of damage dice rolled. You may only use this feature once per turn.

In addition, if it isn't already your Weapon of Choice becomes magical for the purposes of overcoming resistances and immunities.

Lightning Strikes

By 10th level, as you continue to hone and perfect your abilities, you have mastered how to make them with reliable and repeatable rapidity. As a bonus action on your turns, if you take the attack action with your Weapon of Choice, you may use your bonus action to make an additional melee weapon attack with your Weapon of Choice. Additionally, when you use your Action Surge feature, so long as one of the actions you use is the attack action with your Weapon of Choice, you may instead use your bonus action to make two additional melee weapon attacks with your Weapon of Choice instead of only one.

Repelling Strikes

By 15th level, you have not only truly mastered and honed your offensive techniques with your Weapon of Choice, but you have also learned to master your defensive techniques as well. Once per short rest whilst wielding your Weapon of Choice, when hit by an enemy attack you may use your reaction to add your proficiency modifier to your Armour Class. As part of this reaction, you may make one melee weapon attack with your Weapon of Choice on a creature within your weapon of Choice's reach.

Warrior of Legends

At 18th level, you have finally truly mastered your blade and its ability to the utmost - the stuff of legends themselves. Your technique is truly consistent and repeatable in every fight you make. You gain an additional use of your Fighter Action Surge feature, and an additional use of your Fighter Second Wind feature. In addition, as a reaction to taking damage, you can also use your Second Wind feature.
