Unholy Sacrifice

You sacrifice some of your health to mend another creature’s injuries. You take 1d6 Necrotic damage, which can’t be reduced in any way, and one creature that you are touching regains a number of hit points equal to double the Necrotic damage you took.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
