Aalbar's ring summons a mystical ring of golden sand that sprays out of the caster's hand and forms a circle of glyphs. After Aalbar's ring is cast, you may add four to your armor class to stop any attack that would have hit you without that bonus. However, after Aalbar's Ring blocks an attack, it cannot be used in that same way until after your next turn. Instead, it gives you resistance to nonmagical attacks that deal bludgeoning, piercing, or slashing damage. The ring lasts for one minute or until it is dispelled, which requires a bonus action. When Aalbar's ring is dispelled, the sand that forms the ring falls to the ground and gives you 1d6 temporary hit points. This effect does not trigger if the ring wears off on its own.
