Divine Retribution

You speak a prayer to your patron and focus their divine wrath towards the creature that damaged you. The creature must make a Charisma saving throw. It takes 2d10 radiant (if you are good or neutral) or necrotic  damage (if you are evil) on a failed save, or half as much damage on a successful one.

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