Punishing Smite

Those that have done wrong are not always fully aware of their guilt. Correct this error.
The first time you hit with a melee weapon attack during this spell’s duration, radiant fire and chilling shadow pours forth from opposite sides of your weapon. The attack deals an extra 2d10 necrotic damage and 2d10 radiant damage to the target. Additionally, if the target is a creature, a terrible judgment descends upon them, leaving them vulnerable to attack. Whenever the target takes damage from an attack before the spell ends, they take an additional 1d10 force damage.
