Eerie-Impulse is an Electric-type move with no power and 100% accuracy. Instead of dealing damage, it sharply lowers the target's Special Attack stat by two stages. Eerie-Impulse is useful in both casual and competitive play for disrupting special attackers, reducing the amount of damage they can deal with their special moves. It adds a strategic layer to battles, especially when facing Pokémon that heavily rely on special attacks to deal damage. The move was introduced in Generation VI and has since been a tactical choice for trainers looking to weaken their opponent's offensive capabilities.
