Blood Mage

Blood can be a source of magical energy for those willing to make the necessary sacrifices, whether those be personal or dark and forbidden.

Wizard Specialty

A blood mage powers their magic with the secrets they learn from their own blood. Eventually, they learn to manipulate the blood of others as well.
 

Blood Savant

2nd-Level Blood Mage Feature
The gold and time you must spend to copy a blood magic spell into your spellbook is halved.
 

Bonus Proficiency

2nd-Level Blood Mage Feature
You gain proficiency in Medicine.
 

Internal Fortitude

2nd-Level Blood Mage Feature
You also gain a greater awareness of the blood flowing through your veins and of the heart that pumps it—and some measure of control over both. When you are subjected to a disease or poison effect that allows a Constitution saving throw to take only half damage, you instead take no damage on a successful save and only half damage on a failed one.
 

Blood Vision

6th-Level Blood Mage Feature
You can see a moment of the past through the eyes of a creature by consuming its blood. Upon ingesting a small amount of the blood of another creature, you become stunned. While stunned, you experience one of the creature’s memories through its own eyes. (The memory may or may not be about the incident that caused it to bleed.) Once you have consumed a creature’s blood for this purpose, the creature is immune to further uses of this ability.
 

Absorb Toxins

10th-Level Blood Mage Feature
You can absorb a poison or a disease from another creature, living or dead, and turn it to your use. By exposing a fresh wound to a source of disease or poison, you can safely absorb it and store it, dormant, in your bloodstream. You can then inflict the disease or poison on another creature by spitting a stream of blood at it. As an action, you make a ranged spell attack. On a hit, the target is exposed to the disease or poison and must proceed with any saving throws required.
If you do not pass the disease or poison along to another living creature within three days, it becomes active in the body, and you must make the first two saving throws required by the disease or poison with disadvantage.
 

Thicken or Quicken Blood

14th-Level Blood Mage Feature
You can turn another creature’s blood into sludge, hampering the creature, or you can thin it out, giving the creature extra mobility. As an action, you can cause a touched creature that fails a Constitution saving throw to become affected as if by a slow spell—or alternatively, to gain the effect of a haste spell. The duration of either effect is a number of rounds equal to your Intelligence modifier. The target of the haste effect can intentionally fail the saving throw. You can use this ability once, regaining the use of it upon finishing a long rest.
