Cleaving Smite

The next time you hit a creature with a weapon attack before this spell ends, the weapon shines with bright light as you strike, dealing 2d6 radiant damage to the target and 1d6 radiant damage to a creature of your choice within 5 feet of the target.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the radiant damage increases by 1d6 for each slot level above 2nd.
