Bloodhooks are predators who turn the battlefield into a hunting ground. With jagged hooks and chains, they close the gap in an instant, dragging prey into their reach or hurling themselves headlong into the fray. Where others falter, they endure—each strike and every wound feeding into a grim alchemy of blood and death. By hurling grisly projectiles infused with necromantic energy, a Bloodhook rends both flesh and spirit, detonating their quarry in bursts of gore that restore their own vitality.

Whether born of a cursed hunting tradition, gladiators who survived by clawing life from their foes, or forgotten warbands who bound themselves to the flow of blood itself, all Bloodhooks embody the same brutal truth: survival belongs to those who chain their enemies, tear them apart, and drink deep of the violence.

Claw Shot

At third level you create a wrist mounted device. You can use this device as you are proficient with it. As a bonus action you can shoot out a grappling hook from the device. The grappling hook can pull something toward you, or launch you forward. When you use your claw shot you can either choose to pull or launch.

Pull:

You shoot out a grappling hook to any point within 60 feet of yourself. If the point is on an object you can attempt to pull that object toward you. If the point is on a creature, the creature must make a strength saving throw against your save DC (8 + your proficiency bonus + your strength or Dexterity modifier). On a successful save, the creature is not moved. On a failed save you pull the creature, in a straight line, to any point between you and it.

Launch:

You shoot out a grappling hook to any point within 60 feet of yourself. If the point is on the ground, a large creature, or an object that is anchored enough, you can attempt to pull yourself toward that in a straight line. 

Whether you choose to pull or launch, if the grappling hook hits a creature, the creature takes piercing damage equal to 1d4 + your Str/Dex bonus.

beyond this you gain proficiency with tinker's tools so you can do maintenance on your device during rests.

Bloodflare

Level 3: Bloodflare

At level 3, your wrist mounted device can also harm your foes with explosive force.

As an attack, you shoot a fiery explosion from your wrist mounted device  as part of this you can "mark" one creature who will then have disadvantage and you will regain HP equal to half the damage they sustain from this. Each creature in a 20ft sphere originating from you must make a dexterity saving throw. On a failed save, a creature takes 4d6+5 fire damage, is pushed 5ft away, and is knocked prone. On successful save, the creature takes half damage, is not pushed back, and is not knocked prone.

You can use this a number of times equal to your proficiency bonus and regain use of this ability when you finish a long or short rest. You also regain use of this ability whenever you roll damage against a creature with a great sword or maul and both of the numbers on the rolled damage die are the same. The damage must be dealt to a hostile enemy and not a defenseless creature, you psychopath.

The damage increases to 6d6+5 at level 5, 8d6+5 at level 10, and 10d6+5 at level 15.
