Air Shield

An invisible barrier of magical air appears and protects you. Until the start of your next turn, you have a +2 bonus to AC, including against the triggering attack, you take no damage from non magical ranged attacks and you take no damage from magic missile. If you get hit by a melee attack while under the effects of the spell, the creature must make a constitution saving throw. If the creature fails the saving throw, it is pushed 15 feet to the opposite direction of the attack.
