Defiant Retribution

You brandish the weapon used in the spell’s casting and make a melee attack with it against one creature within 5 feet of you. On a hit, the target suffers the weapon attack’s normal effects and is wreathed in holy fire, scourging those who would defy your will. If the target succeeded a saving throw for enchantment spell of 1st level or higher on your turn, it takes an additional 1d8 radiant damage, and the spell ends.

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d8 radiant damage to the target on a hit, and the damage taken by a target who succeeded an enchantment saving throw increases to 2d8. Both damage rolls increase by 1d8 at 11th level (2d8 and 3d8) and again at 17th level (3d8 and 4d8).
