Blood Fever

A blood mage's skill is not limited to the scarlet rivers than run through their own bodies. This spell requires a 1d4 blood sacrifice. Upon casting, you select one creature that you can see within 60ft. Your blood sorcery locks onto this creature's own blood-essence. You cause a venous eruption, dealing 2d4 damage automatically. On your next turn you can trigger another eruption on the same character without additional sacrifice.

You may choose to use your bonus action to target a new creature with this spell for a 1d4 sacrifice.
