Sacrifice

A Warlock of Sacrifice is one that went through a great ordeal for long amounts of time, be it torture or living in a painful setting. They have almost given up multiple times, but pushed forward in order to perhaps finally reach a point where they are free from pain. A patron that would offer them this freedom is one that is heavily related to suffering, torturing, pain, hard work or even blood. They would look down upon this being and say that they deserve a life of power, and grant it to them.

Pain Tolerance

Through the tolerance of various kinds of pain, your ability to resist pain has toughened your resolve and body. Your hit point maximum increases by 2 for every warlock level you have.

Torturous Power

Your patron has given you the ability to turn pain into power. By spending an action, you can cast a spell by taking necrotic damage equal to 5 times the spell slot level, this necrotic damage bypasses immunities, resistances and temporary hit points. This can only be used 2 times per short rest.

Reinvigorating Suffering

When you drop a creatures hit points to 0 with a spell, you may use a reaction to absorb their life essence in order to restore your hit points. The amount restored is equal to your warlock level + the spell slot level used. You can use this a number of times equal to your charisma modifier per long rest.

Bloody Ward

After using the Torturous Power feature, you gain a number of temporary hit points equal to double the amount of necrotic damage you took for one hour. Additionally, as an action, you can remove any temporary hit points early, zapping a creature within 30ft for necrotic damage equal to the amount removed.

Crimson Flood

Whenever you drop to 0 hit points, your body's blood explodes outwards, dealing force damage to creatures of your choice within 30ft equal to your warlock level. For each creature that gets hit by this feature, you restore hit points equal half of your warlocks level (minimum of 1 if no creatures were hit). If this drops a creature to 0 hit points, you can activate Reinvigorating Suffering as if it was a 5th level spell that was cast. This feature can only be used once per long rest
