Shadow Shield is a specialized Pokémon ability largely affiliated with the Legendary Pokémon Lunala. This ability confers a significant defensive advantage when the Pokémon's health is at maximum. Specifically, Shadow Shield mitigates damage taken from any attack by 50% when the Pokémon's HP is full.
This damage minimization feature only functions when the Pokémon's HP is at its peak, thereby making healing moves, items such as Sitrus Berry, and the implementation of moves like "Protect" or "Roost" strategically important to preserve this advantage during battles. After the Pokémon sustains some damage causing its HP to decrease below 100%, Shadow Shield ceases to diminish the incoming damage.
In competitive play, Shadow Shield is exceedingly powerful as it enables the Pokémon to withstand potentially destructive hits that could otherwise bring about a swift defeat, thus providing openings for counterattacks or establishing beneficial circumstances for the battle.
