Order of the Exquisite Blood

"To defeat a monster; you must become one

Hiding in the daylight away from the Sun.

For darkness is the best to devise your sinister plans

To kill the monster who ruined you with your own hands.

Let the fire in hell break loose.

Let the monster beg for it's life.

Tell him that it is of no use.

Burn him with your unforgiving eyes.

To defeat the monster you became one

Sadly, now you are a monster too son!"

-Adi

• Tooth and Nail. Your canines elongate, becoming vicious fangs. Your nails harden and polish, lengthening into natural stilettos. (You determine their length.)
• Undead Nature. You age Much slower at a rate of 1 year every 50 years and can't be magically aged. You are immune to disease and gain resistance to necrotic damage, along with bludgeoning, piercing, and slashing damage from non-magical attacks. You also no longer need to sleep and can’t be forced to sleep by any means. To gain the benefits of a long rest, you can spend all 8 hours doing light activity, such as reading or keeping watch.

Flaws:

• Sunlight Sensitivity. You have disadvantages on all ability checks in direct sunlight.

• Stake to the Heart. If a piercing weapon made of wood is driven into your heart while incapacitated in its resting place, you are paralyzed until the stake is removed.
• Bloodlust. You are required to drink blood once every two days. After two days without drinking blood, you gain 1 level of exhaustion, and you gain 1 more level of exhaustion for every additional day without blood. Drinking source of blood will reduce your exhaustion level by 1, per pint (one round) of blood. Blood can satisfy food and drink requirements rather than consuming normally, but you can still eat/drink.

At 7th level, you gain the ability to climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Additionally, you can use your reaction when you fall to reduce any falling damage you take by an amount equal to five times your blood hunter level.

Brand of Forbidden Light

Beginning at 11th level, your Brand of Castigation now illuminates the area with sunlight.

Day Walker

You no longer suffer disadvantage to all ability checks in direct sunlight, and can pass over running water and are no longer damaged by it. You also only need to feed on blood once a week as opposed to every other day.
