Blood Fiend

Blood Fiend combines the martial mastery common to all Fighters with mastery over their own lifeblood. Their blood both complement and extend their combat skills, providing additional protection to shore up their armor and also allowing them to engage many foes at once with blood manipulation.

These Fighters are cursed by Ancient Power, granting them command over their own blood, but at a price.

Level 3: Level 3: Bloodforged

You learn a ritual that creates a tether of blood, wrapping the tether around your arms and the handle of a chosen weapon. You perform the ritual over the course of 1 hour, which can be done during a Short Rest. The weapon must be within your reach throughout the ritual, at the conclusion of which you touch the weapon and forge the tether. 

Once you have tethered a weapon to yourself, you can’t be disarmed of that weapon unless you have the Incapacitated condition. If it is within 15 feet of you, you can pull the weapon back to your hand as a Bonus Action, causing it to fly through the air, hitting any enemy in the way for 1d4 bludgeoning damage. If another creature wields the tethered weapon, make a Strength Check against it to recall the weapon. Any attacks made on you with a tethered weapon is made with disadvantage.

You can have up to two tethered weapons, but you can recall only one at a time with a Bonus Action. If you attempt to tether a third weapon, you must break the bond with one of the other two.
