An attack that may lower Speed.
Bubble Beam is a Water-type special move with a base power of 65 and an accuracy of 100%. It has a 10% chance to lower the target's Speed stat by one stage, making it a useful move for not only dealing damage but also potentially hindering the opponent's ability to outspeed the user in subsequent turns. In Polished Crystal, Bubble Beam can be learned by various Water-type Pokémon, providing them with a reliable offensive option that can also contribute to controlling the pace of battle.
