Charismatic Shield

For the duration of this spell, you add your Charisma modifier to your AC.  In addition, each creature within 50 feet of you that targets you with an attack or a harmful spell must make a Wisdom saving throw. If the saving throw fails, the creature must target another creature or lose the action, and it can’t target you again for the duration of the spell. If you attack or cast a harmful spell against that creature, the spell’s effect against that creature is broken, and it can target you normally.
