Sanguine Bloodline

The Sanguine sorcerer has a unique relationship with blood. While other Sorcerers draw power from their bloodline, Sanguine sorcerers draw power from their blood itself. The ability to do so is hereditary, and frequently will not manifest for generations. This manifestation generally occurs under times of extreme stress, when the Sorcerer is unable to help themselves or another. This type of extreme stress causes the dormant power of the blood to be awakened, and the new Sorcerer takes their first steps. The power of the Sanguine sorcerer's blood is taboo in most civilized societies, and causes those who know of it to be wary of the user.

Your blood allows you to modify your spells in many different ways, though at the cost of your health.

When you use this ability with a metamagic you know, you can choose to replace the cost in sorcery points with hit points, at a rate of 2 hit points per sorcery point. When you use this ability with a metamagic you do not know, you must spend the sorcery points, as well as 3 hit points per sorcery point spent. Any damage dealt by this feature cannot be reduced in any way, and ignores any temporary hit points, other than those granted by the Blood Pooling class feature.

You can use this ability a number of times equal to 1+ your Constitution modifier (minimum 1) per long rest.

Blood Siphon

At 18th level, you can use the blood of those around you to cheat death.

You heal for half of any damage caused this way, up to half of your maximum hit points.
