Blood Blade (H)

You summon forth a blade formed from blood. The blade can be a dagger, shortsword, longsword or greatsword. You're proficient and do its corresponding damage type + your SAM. The weapon can be used to make melee attacks using your SAM.

You can voluntarily lose hit points when you cast the spell. If you do, attacks with the weapon do the number spend as extra necrotic damage. You can dismiss the spell as a bonus action. The blade vanishes if you let go of it.
