Helios' Embracing Sanctuary

You ward a creature within range against attacks. Until the spell ends, any creature who targets the warded creature with an attack or a harmful spell must first make a Wisdom saving throw. On a failed save, the creature must choose a new target or lose the attack or spell. This spell doesn’t protect the warded creature from area effects, such as the explosion of a fireball. Once a creature has succeeded on the saving throw it is no longer affected by the spell when cast on the same warded creature for the next 24 hours. 
If the warded creature attacks a creature, that creature is no longer affected by the spell on the warded creature for the next 24 hours. Additionally, if a creature is within the area of a damaging effect created by or directly resulting from the warded creature's action, it may make a saving throw against the spell with advantage.
