Celestial Wrath

You channel holy energy, making it coalesce around your fist. Make a melee spell attack against one creature within 5 feet of you. On a hit, the target takes 1d10 radiant damage. After you make the attack, the energy dissipates.

The spell’s damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
