Nightblade

Nightblades have learned how to fight with fighter tactics and weapons while still keeping their stealthy edge. Nightblades are usually soldiers in war, or maybe spies who infiltrate enemy defences. 

Martial training

At level 3, training in fighter arts has granted you proficiency with martial weapons, medium armor, and shields. 

Action Surge

Starting at 3rd level, you can push yourself beyond your normal limits for a moment. On your turn, you can take one additional action on top of your regular action. You must finish a long rest before using it again.

Precice Strike

Starting at level 9, you can choose to forgo advantage on a sneak attack to do more damage. If you choose to forgo advantage and the sneak attack hits, the target takes an extra 3d6 damage of that weapons type.

Martial Advantage

At level 9, you are no longer restricted to sneak attack with finesse or light weapons only. You can now sneak attack with any kind of weapon, given the weapon is not heavy. 

Battle Ready

At level 13, you learn how to prepare for a fight quickly. When you roll initiative and have less than half of your hit points remaining, you recover 2d10 hit points. 

Action Blitz

Starting at level 17, when you use your action surge, you may take 3 additional actions. If you choose to do this, you gain one level of exhaustion.
