An attack that may lower Sp.Def.
Acid is a Poison-type special move that has a base power of 40 and an accuracy of 100%. In addition to dealing damage, Acid has a 10% chance to lower the target's Special Defense stat by one stage. This makes Acid not only a reliable offensive option but also a strategic move for weakening the opponent's defenses against special attacks. In Polished Crystal, Acid can be learned by various Poison-type Pokémon, providing them with a useful tool for both damage and debuffing in battles.
