Defiant smite

The first time you hit with a melee weapon attack during this spell’s duration, wrathful energy rushes through your weapon. The attack deals an extra 1d6 force damage to the target. Additionally, if the target is a creature, its ability to attack is hindered. Until the spell ends, the creature must make a Charisma saving throw at the start of each of its turns. If it fails, the first time it hits with an attack before the end of its turn, it is knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the initial extra damage dealt by the attack increases by 1d6 for each slot.
