sanctuary V S M

You ward a creature within range against attack.
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 o f a fireball. If the warded creature
makes an attack or casts a spell that affects an enemy
creature, this spell ends.
