Drain Life

You tear the essence of life from one creature you can see within range, causing terrible pain. The chosen creature makes a Constitution saving throw. On a failed save, you deal 2d6 necrotic damage and regain HP equal to half the total damage dealt. On a successful save, the chosen creature takes half as much damage and no healing is received.

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.
