Swift Soldier

(Formerly known as the Samurai)
The Swift Soldier is a fighter who specialises in their quickness and agility, having a phenomenal speed that allows them to dart around in combat. Able to balance both speed and accuracy, the swift soldier attacks in quick bursts and overwhelms their opponents with their speed and rapid attacks.

Natural Quickness

Beginning when you choose this archetype at 3rd level, you learn to be quick and agile without exerting yourself. Your walking speed increases by 5ft. You also gain proficiency in the Dexterity (Acrobatics) or Strength (Athletics) skill (your choice), and can add your proficiency bonus to your Initiative when you enter combat.
When you reach 10th level, your walking speed increases by an additional 5ft.

Side-stepping Swiftness

Starting at 3rd level, as a bonus action on your turn, you can enhance your swiftness and defences. Your speed increases by 20ft, and your movement does not trigger opportunity attacks until the end of your current turn. Additionally, when you activate this feature, you gain 5 temporary hit points. The number of temporary hit points increases when you reach certain levels in this class, increasing to 7 at 7th level, 10 at 10th level and 15 at 15th level.
You can use this feature two times, and regain all expended uses when you finish a short rest. At 7th level, you can use this feature three times before finishing a short or long rest and four times at 15th level.

Unerring Accuracy

Starting at 7th level, you can empower your intensity in battle to help you strike true. As a bonus action on your turn, you can give yourself advantage on all weapon attack rolls until the end of the current turn. After activating this feature, you can add 1d6 damage to one weapon attack you hit on the current turn.
You can use this feature three times, and regain all expended uses when you finish a short rest. When you reach 15th level, you can use this feature four times before needing to complete a short rest.

Blink Attack

At 10th level, you learn to move and strike within the blink of an eye. As an action, you can magically teleport to an unoccupied space within 30ft. Immediately after teleporting, you can make one weapon attack against a creature within range.
Once you use this feature, you can't use it again until you finish a short rest. When you reach 15th level, you can use this feature twice before needing to complete a short rest.

Rapid Strikes

Starting at 15th level, you learn to trade accuracy for swift strikes. If you take the Attack action on your turn and have advantage on an attack roll against one of the targets, you can forgo the advantage for that roll to make an additional weapon attack against that target, as part of the same action. You can do so no more than once per turn.

Deft Mastery

Starting at 18th level, you can unleash your power in a balanced display of speed and accuracy. When you activate either your Side-stepping Swiftness feature or Unerring Accuracy feature, you can activate the other feature with the same bonus action. Once you perform this, you can’t do so again until you finish a long rest.
Additionally, when you roll initiative and have no uses of either Side-stepping Swiftness feature or Unerring Accuracy feature, you regain one use of both features.
