Drifter Fighter

Bonus Weapon Change

At 3rd level, Longswords count as finesse when you wield them, and count as finesse for features such as Defensive Duelist

Light Dash

At 3rd level, you can use an action or bonus action once per round to move 30 feet in a straight line in any direction, leaving behind you a colorful cascade of illusory duplicates which dissipate instantly. This movement does not provoke attacks of opportunity and can cover gaps and difficult terrain freely, but you can't move through walls or over cover.

Dash Strike

Starting at 7th level, whenever you use your action to Light Dash, you can immediately follow the Light Dash with one weapon attack, which can be either melee or ranged. You can make two attacks following a dash starting at 11th level, and three attacks starting at 20th level.

Deflecting Dash

At 10th level, you gain the ability to Light Dash as a reaction to getting hit by a ranged weapon attack. When you do so, the damage you take from the attack is reduced by 1d10 + your Dexterity modifier + your Fighter level.

In addition, you can now make two Light Dashes per round, which can be any combination of Light Dashes used as actions, bonus actions, or reactions.

Deflecting Blade

At 15th level, you gain the ability to attempt to deflect incoming projectiles with your melee weapon. As an action on your turn, you can ready yourself against incoming projectiles. Until the start of your next turn, whenever a ranged weapon attack is made against you, roll an attack roll with your melee weapon. If your attack roll is higher than the ranged attack's, you deflect the projectile. If your attack roll minus the difference between your roll and the ranged roll clears the Sender's AC, it hits them instead, dealing the damage the attack would have done against you.

Slash Dash

At 18th level, you gain the ability to, as an action on your turn, make a special Light Dash that you can use to dash through creatures. When you do this, you can make a melee attack against every creature you pass through in the 30 foot line. Because this is a special Light Dash, you can not make attacks after it as with the Dash Strike feature, and it takes both usable dashes in one round.
