You create two small shields of ice and frost roughly 2 feet in diameter, which rush to a creature of your choice which you can see within range and orbit the creature for the duration. The creature gains a bonus to their AC equal to the number of shields floating around them for as long as the shields exist.
At any time before the spell ends, if the warded creature takes damage from an attack roll, one of the ice shields is hurtled forward at the creature that dealt the damage, as long as it is within 30 feet. That creature must make a dexterity saving throw against your spell save DC, taking 3d4 cold damage on a failed save, or half as much damage on a successful one.
After one of the shields has retaliated in this way, it is destroyed and the number of shields and the benefiting creature's AC are reduced by 1. When there are no shields remaining, the spell ends.
At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, you create one additional shield for each level above 2nd.
