Shell Smash is a non-damaging Normal-type move with perfect accuracy. When used, it sharply lowers the user's Defense and Special Defense by one stage each, while dramatically boosting the user's Attack, Special Attack, and Speed by two stages each. This move can significantly turn the tide of battle, enabling the user to outspeed and overpower opponents. Due to its risk-and-reward nature, it's commonly used by Pokémon with sturdy defenses or those holding items like White Herb to negate the defensive drops. It's a favorite in competitive play for setting up sweeps or breaking through tough defenses.
