As an action, you sacrifice some of your health to mend another creature’s injuries. You take 5d4 + your spellcasting ability necrotic damage, which can’t be reduced in any way, and a creature that you can touch or see within 5 meters regains an amount of health equal to twice the necrotic damage you take.

Augment

You can increase the damage by 7d4 for each additional mana expended.
