Delay Pain

With a flash of blue, you redirect an enemy attack into a different dimension - temporarily. As a reaction upon being hit with an attack, but before the damage is sustained, you may choose to instead take no damage. The DM records the amount taken and type of damage. Roll a D20. On a 19 or lower, you take the damage immediately when this spell ends or you lose concentration. On a natural 20, you instead take no damage.
