Order of the Blood Knight

The Order of the Blood Knight is an order of hunters who specialize in fighting living creatures that pose a threat to the realm, known to many as "mage hunters". They expand their abilities of blood manipulation to strengthen themselves and weaken their foes. A blood knight turns their pain into strength, and their quarry's pain into their strength as well. Their hunt is focused on villains that are still living - evil wizards attempting profane rituals, cults that sacrifice innocents to demons, etc.

Bloodthirsty Smite

When you join this order at 3rd level, you learn to channel your hemocraft into your Crimson Rite, drawing the blood of your enemies to you instantaneously.

When you hit a creature with a weapon on which your Crimson Rite feature is active, you can expend a use of your Blood Maledict feature. If you do, roll one of your hemocraft die and add the result as necrotic damage to the attack, and you regain hit points equal to the necrotic damage dealt by this feature.

Hemocraft Mastery

Also starting at 3rd level, you learn to master blood curses and your use of blood.

You gain an additional use of your Blood Maledict feature. In addition, once per long rest, you can spend a bonus action to recover a number of uses of your Blood Maledict feature equal to your hemocraft ability modifier (minimum 1).

Misery's Company

Upon reaching 7th level, you can convert your pain into power and retaliate against those who would do you harm.

For every 10 hit points you are below your hit point maximum, your weapon attacks get +1 to attack and damage rolls, up to a maximum of your Constitution modifier.

Brand of Bloodletting

Starting at 11th level, your Brand of Castigation weakens your foe's life force and leaves them vulnerable to your hemocraft-empowered strikes.

Whenever you use your Bloodthirsty Smite feature on a creature bearing your Brand of Castigation, you roll an additional hemocraft die when determining the extra necrotic damage you deal (and subsequently the amount of hit points you regain).

Vision of Scarlet

At 15th level, your uncanny ability to seek out blood has been honed to a sixth sense, and you can magically disassemble your body into a bloody mist and instantaneously reconstitute next to a creature you sense around you.

As an action, you can sense the presence of any creature with blood within 60 feet of you, regardless of cover or magical effects (such as illusions or invisibility) that would conceal them from you. As part of the same action, you may magically teleport to an unoccupied space you can see within 5 feet of one of those creatures. You must complete a short or long rest before using this feature again.

Sanguine Clarity

Upon reaching 18th level, you become more focused and dangerous when bloodied.

While you have less than half of your total hit points, you cannot be charmed or frightened, you have resistance to psychic damage, and you can use your Bloodthirsty Smite feature without expending a use of your Blood Maledict.
