Binding Smite

The next time you hit a creature with a melee weapon attack during the spell’s duration the attack deals an extra 1d6 radiant damage to the target and magical restraints appear around the target. The target must make a Strength saving throw. On a failed save the target is restrained and their movement speed is reduced to 0 until the end of your next turn.

At Higher Levels. When you cast this spell using a spell slot of 3nd level or higher, the extra damage dealt by the attack increases by 1d6 for each slot.
