Void Knight

Your encounters with the Void have changed you. A piece of that darkness has taken root inside you, feeding on your sorrow, nourished by your rage. Your swings leave trails of Void that eagerly consume the essence of your foes, darkness eating them away from the inside out. This darkness inside you is growing, with every strike imbued with its power you feel more of who you were slipping away, you wonder if eventually, you’ll be any different than the creatures that stole this world’s future… and whether or not you will care

Echo

Beginning when you choose this archetype at 3rd level, the void begins to trail your movements, almost like an echo. You may expend one of your hit dice and roll it to add that much necrotic damage to your attack.

You gain the ability to expend up to one more additional die at 7th, 10th, and 15th level.

Time Rot

Starting at 7th level, when a creature moves within 10 feet of you, you may use your reaction and expend a hit die to slow their actions with void energy. Until the end of their next turn that creature's movement speed is halved, and they may either take an action or a bonus action on its turn, not both.

Additional Fighting Style

At 10th level, you can choose a second option from the Fighting Style class feature.

Archery

You gain a +2 bonus to attack rolls you make with ranged weapons.

Defense

While you are wearing armor, you gain a +1 bonus to AC.

Dueling

When you are wielding a melee weapon in one hand and no other weapons, you gain a +2 bonus to damage rolls with that weapon.

Great Weapon Fighting

When you roll a 1 or 2 on a damage die for an attack you make with a melee weapon that you are wielding with two hands, you can reroll the die and must use the new roll, even if the new roll is a 1 or a 2. The weapon must have the two-handed or versatile property for you to gain this benefit.

Protection

When a creature you can see attacks a target other than you that is within 5 feet of you, you can use your reaction to impose disadvantage on the attack roll. You must be wielding a shield.

Two-Weapon Fighting

When you engage in two-weapon fighting, you can add your ability modifier to the damage of the second attack.

Relentless

Starting at 15th level, you may regain 2 hit dice when you begin combat, up to a number of times equal to your constitution modifier per long rest.

Survivor

At 18th level, you attain the pinnacle of resilience in battle. At the start of each of your turns, you regain hit points equal to 5 + your Constitution modifier if you have no more than half of your hit points left. You don’t gain this benefit if you have 0 hit points.
