Sharply raises the user's Sp.Def.
Amnesia is a Psychic-type status move that sharply raises the user's Special Defense stat by two stages. This allows the user to better withstand special attacks from opponents, making it a valuable move for increasing survivability in battle. Amnesia has an accuracy of 100%, ensuring that it will successfully boost the user's Special Defense unless affected by accuracy-reducing conditions. In Polished Crystal, Amnesia can be learned by various Psychic-type Pokémon, providing them with a strategic option to enhance their defenses against special attacks.
