Blood Bargain

You sacrifice some of your health to mend another creature’s injuries. You take 2d4 necrotic damage, which can’t be reduced in any way, and one creature of your choice that you can see within range regains a number of hit points equal to the necrotic damage you take plus your spellcasting modifier. The target has resistance to non-magical bludgeoning, piercing, and slashing damage until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d4 for each slot level above 1st.
