The Demon

After making a pact with a demon, you have been granted the forbidden knowledge of blood magic. Whether you get the blood by harming yourself, or another, it doesn't matter. All you need is the crimson vitae in order to cast your spells, even amplifying your magic. All will bow to your will.

Blood Magic

You can use your blood as an arcane focus, by taking 1d4 unsoakable damage. Alternatively, you can use the blood of another humanoid in this same fashion, willing or otherwise. Any damage received in this way is only partially affected by magical healing.

Blood Sacrifice

The blood mage sucks 2d4 + Charisma modifier life-force from another creature with blood, healing the caster but potentially killing the target. This healing is not affected by the healing penalty of Blood Magic. You can use this as many times as equal to your proficiency bonus, and you regain all expended uses after completing a short or long rest.

Blood Wound

The blood of all hostile targets in a 30 ft. radius boils within their veins, inflicting 2d10 necrotic damage. Targets stand twitching, stunned unless they pass a Constitution save, taking only half damage. Creatures without blood are immune.

You can use this feature once per short or long rest.

Blood Control

The blood mage forcibly controls the target’s blood, making the target an ally of the caster unless it passes a Constitution save. If the target resists, it still takes full 10d10 psychic damage from the manipulation of its blood, but still maintains control of its mind. Creatures without blood are immune.

You can use this feature once per long rest.
