The ancient and forbidden tradition of Hemomancy teaches that their is magic within the blood of every living thing, and that those who can tap into this magic can obtain power unlike any other. Called Hemomancers or 'Blood Mages', followers of the tradition of hemomancy focus on spells that can affect both the blood of others, as well as their own. Many of these wizards practice their art in secret, though the knowledge and practice of such magic can allow them to work as doctors, shamans, or assassins.

Beginning at 2nd level, you have learned how to draw power from your blood to harm others. As a bonus action, you can cause your blood to become volatile. Until the end of your next turn, whenever you take damage from a creature you can see, that creature takes necrotic damage equal to your wizard level plus your intelligence modifier. This feature can only effect a creature once per turn.
