Blood Bounded

Your magic is connected deep in the pathways of your body and soul, pulsing from your own blood. Ancient magic awakens in these few that possess this crimson power.

Blood Bound Weapon

Starting at 1st level, as a bonus action, you spend 1 hit die and roll it, you take half the amount rolled as necrotic damage to bring forth your blood as a weapon. You can choose the form that this melee weapon takes each time you create it (see the Weapons section for weapon options). You are proficient with it while you wield it. When you attack with that weapon, you can use your Constitution modifier, instead of Strength or Dexterity, for the attack and damage rolls. This weapon counts as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. This ability grows as you take levels in this class. At 6th level you have a +1 to attack roll and damage with this weapon, at 10th level it is a +2, and at 15th level it is a +3. Also, when you hit a creature with your Blood Bound Weapon it leaves a trace amount of your magic blood on the target. This last for up to 1 hour before disappearing. While a creature has your blood on it you have advantage on checks to track that creature (Survival, Perception, etc).

Your Blood Bound Weapon disappears if it is more than 5 feet away from you for 1 minute or more. It also disappears if you use this feature again, if you dismiss the weapon (no action required), or if you die.
