Cleaving Smite

The first time you hit with a melee weapon attack during this spell’s duration, your weapon burst with divine flame, shedding bright light within 10 feet. When making a melee weapon attack, creatures in a 15 foot cone originating from you and facing towards your target must make a Dexterity saving throw. A creature takes 4d6 radiant damage on a failed save, or half as much damage on a successful one. The target of the attack makes this saving throw with disadvantage.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
