Divine Wrath

"Begone from where this light shines...DIVINE WRATH!"

You say these words, a creature in your sight is enveloped in divine light. The creature must make a Wisdom saving throw. If the creature fails, you instantaneously do 4d10 Radiant Damage to the creature. The creature now takes double damage from Radiant damage sources. 

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