Blood Magic

You have learned how to use your body to fuel your magic, giving you the following benefits:

• Your Constitution score increases by 1, to a maximum of 20.
• Blood Sacrifice: As a wielder of life magic, you have learned to draw upon the very essence of living beings to fuel your spells. Whenyou cast a spell using a spell slot, you can sacrifice your own life force or the life force of a willing creature within 30 feet, instead of expending a spell slot. When casting a spell in this way, the creature paying the blood price roles two hit dice for each level of the spell and suffers necrotic damage equals the total number rolled. This damage can't be reduced in any way. The blood sacrifice does not expend any hit dice.

  This sacrifice does not work on spirits, constructs, elementals or undead.

• Infuse Spell: Whenever you roll damage for a spell you've cast of 1st level or higher, you can choose to roll one of your Hit Dice and take necrotic damage equal to the roll plus the spells level to reroll a number of damages dice up to your Intelligence modifier (minimum one). This damage can't be reduced in any way, and you must use the new rolls.
