This spell turns the flesh of a willing creature you touch as hard as adamantine. Until the spell ends, the target has resistance to bludgeoning, piercing and slashing damage, and any critical hit against the creature becomes a normal hit.
Additionally, when the target takes 10 or less damage of a damage type other than psychic or poison damage, the damage is reduced to 0.
