Blood Sacrifice

You draw upon the life force of willing creature that you can see within range to replenish your own health. Creatures without blood (such as elementals) cannot be targeted by this spell. The targeted creature rolls 1d10 and takes damage equal to the result, and you regain hit points equal to the damage taken + your spellcasting ability modifier.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage can increase by 1d10 for each slot level above 2nd.
