Blood Magic

You have learned the dark arts of blood magic, empowering your magic with the blood of living creatures, and learning how to influence and control the minds of others.

• Increase your Constitution score by 1, to a maximum of 20
• Blood Magic Spells. You gain access to blood magic spells (including all enchantment spells and other select spells). You learn your choice of two blood magic spells which are of a spell slot equal to or less than your highest level spell slot. These spells are added to your spells known. When choosing future spells when leveling up you may now also choose from blood magic spells of the appropriate spell slot levels.
• Power of the Blood. When casting a spell with a casting time of 1 action that deals damage you may use a bonus action to empower your spell with blood magic. When you do so you must take up to 5d4 necrotic damage. For each 1d4 of damage you choose to inflict on yourself the spell deals an additional 1d6 necrotic damage to its targets.
• Blood Sacrifice. As an action you may choose to deal damage to yourself or a willing ally. When you do so you are a willing creature within 30 ft. may take up to 30 necrotic damage. In exchange for the damage you may replenish expended spell slots. For every 5 damage dealt you may replenish a single spell level of a spell slot. For example if 10 damage is dealt you may replenish one 2nd level spell slot or two 1st level spell slots. 
• Ineffectual Healing. When you have cast a blood magic spell or empowered a spell with blood magic within the past minute all magical healing is halved.
