Nightblade

Using a combination of quick reflexes and superb acrobatics skills, the Nightblade has a supernatural ability to slip out of harms way and catch opponents off guard.

Starting at 3rd level, as a reaction, when an enemy makes an attack against you, you may contest their attack roll with a Dexterity (Acrobatics) check. If you succeed the contest, you may move 5 feet. If you move out of the range of the attack, you take no damage.

Additionally, when you make an Dexterity (Acrobatics) check to avoid being grappled or a Dexterity Saving throw, if successful, you may also move 5 feet.

The bonus movement increases to 10 feet at 9th level, 15 feet at 13th level, and 20 feet at 17th level.

Blurred Step

Starting at 3rd level, when you take the disengage action, you can teleport 5 feet as part of that action, provided you have line of effect and line of sight with the destination. This increases to 10 feet at 9th level, 15 feet at 13th level, and 20 feet at 17th level.

Warp Strike

Starting at 9th level, the short range and long range distance for throwing weapons doubles for you.

When you make a successful thrown weapon attack, you may choose to teleport adjacent to the target and make a second attack with advantage.

Starting at 13th level, when you use your reaction to contest an attack roll with a Dexterity (Acrobatics) check, if you move to a position opposite of the target (where your two positions would be considered flanking), you may make an opportunity attack against the target.

If the target had disadvantage on the attack roll against you, you gain advantage on this opportunity attack and deal Sneak Attack damage.

Swift Reactor

Starting at 17th level, you have two reactions per round.
