Entangling Smite

The next time you hit a creature with a weapon attack before this spell ends, the weapon becomes wrapped with vines as you strike. The attack deals an extra 2d6 bludgeoning damage to the target, which has its speed halved for the duration, and must succeed on a Strength saving throw or be restrained by the entangling plants until the spell ends. A creature restrained by the plants can use its action to make a Strength check against your spell save DC. On a success, it frees itself.

At higher levels, the bonus damage increases by 1d6 for each level above 2nd.
