Vindictive Lash

You injure your own body, and project the pain at an enemy within range. You deal 1d10 necrotic damage to yourself, and the target must make an Intelligence saving throw. On a failed save, the target takes psychic damage equal to twice the damage you dealt to yourself. If you are within 5ft of the target, they instead take three times the damage you dealt to yourself. If they succeed on the saving throw they take half as much damage.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for every two slot levels above 1st.
