Vanish into Shadows

You vanish into the shadow of a willing creature you choose within 5 feet of you, where you remain for the duration or until the chosen creature is reduced to 0 hit points or dies. Until the spell ends, you are invisible and can't be directly targeted by attacks or other effects. When an attack hits the creature, the attacker can choose to deal damage to you or the creature, or to both.

When the spell ends, you leave the creature's shadow, appearing in a spot of your choice within 5 feet of the creature.
