Divine Wrath

You call the wrath of the heavens down upon your surrounding foes. Each creature in a 15-foot cube originating from you must make a Wisdom saving throw. On a failed save, each creature takes 3d8 Light damage. On a successful save, each creature takes half damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.
