Ancient Blood

One of the oldest living strains of Lycanthrope blood, strengthened and honed over many years by the  Hunter's Bane and Volgrid's mastery of his lycanthropy. A transfusion of this blood would most likely kill someone, but it carries uncanny strength, granting Volgrid his incredible power. Perhaps someone might be able to use it...

 - At the beginning of combat, then once every minute while in combat, if he has at least one hit point, Volgrid gains 2d10 + his constitution modifier bonus hit points. 

- Volgrid has advantage on initiative rolls and cannot be surprised.

- The damage inflicted on Volgrid when activating a Crimson Rite or amplifying a Blood Curse is halved. 

- His strength, constitution, and intelligence scores can exceed 20. 

- He is immune to Necrotic Damage.

- Only one person can be attuned to this blood at any given time. If, through a conscious decision, he decides to un-attune to the blood and let someone else "inherit" it, Volgrid will immediately die. 

IF SOMEONE ELSE WERE TO HAVE A TRANSFUSION OF THIS BLOOD:

- They would have to spend the next eight hours in agony, making one Constitution Saving Throw every hour. They cannot have advantage on these rolls.

-The initial DC is 16, and it increases by 1 for every hour that passes.

- If the user fails on four or more saving throws, they die.

- Each failed saving throw reduces their maximum hit points by 20.

- If they succeed on four or more saving throws by 5 or more, they gain a feat and an ability score increase.

Notes: Bonus: Hit Points, Immunity: Necrotic, Advantage: Initiative, Blood Hunter of Volgrid's choice
