Taunting Smite

The next time you hit a creature with a melee weapon attack, your weapon flares with bright lights, creating a mystifying pattern, and the attack deals an additional 2d8 Psychic Damage, and the target must make a Charisma saving throw. On a failed save, the target can only target the caster of this spell with it's attacks, and cannot move away from the caster. The target repeats this saving throw at the end of each of it's turns until it successfully saves, the spell ends, or the caster falls unconscious.

When casting this spell at higher levels, the damage increases by 1d8 for each level above 3rd.
