Fighter Archetype

Blitz Knight

The Blitz Knight is a warrior trained to use blinding speed, some believe that the original Blitz Knight was a freak offspring of an Elite warrior and some powerful forgotten Elemental. Harnessing inhuman speed, teleporting abilities and lightning blades, the Blitz Knight is a terrifying opponent to face both due to its high mobility and impeccable defense.

Evasive Speed

Starting at 3rd level, you count your Dexterity modifier twice when calculating your AC, the normal dexterity modifier limit of armors still applies. If you use this feature, you can not use a shield.

Counterstrike

When you choose this archetype at 3rd level, If a creature misses your AC with 5 or more, you can use a reaction to teleport to an unoccupied space that you can see within 30ft of you and make a melee attack roll against a creature of your choice. If the attack roll is a critical hit, you can teleport again, to a second creature (this does not consume a second use of this feature). You can use this feature a number of times equal to your Strength or Dexterity modifier, whichever is higher, (a minimum of once). You regain all expended uses when you finish a long rest.

Flying Blade

Starting at 7th level, you can use a bonus action to activate this feature, allowing you to gain increased mobility between your strikes. Whenever you make an attack roll before the start of your next turn, you can as part of each attack teleport to a creature within 30ft of the starting location and make the attack against that creature. This movement does not provoke attacks of opportunity. Once you use this feature, you can’t use it again until you finish a short rest.

Lightning Blade

Always Vigilant

When a creature hits you with a melee attack, you can use your reaction to teleport to an unoccupied space within 10 ft, avoiding the attack completely. You can use this feature a number of times equal to half your Strength or Dexterity modifier, whichever is higher, rounded up (a minimum of once). You regain all expended uses when you finish a long rest.

Faster than magic

Starting at 18th level, whenever you pass a saving throw against a spell or other magical effect from a source you can see, you can instantly teleport to the source of the magic and take your full attack action. Once you use this feature, you can’t use it again until you finish a long rest.
