Shell Smash lowers the user's Defense and Special Defense by one stage each, while also raising Attack, Special Attack and Speed by two stages each.
Stats can be raised to a maximum of +6 stages each, or lowered to a minimum of -6 stages each.
When a Pokémon is holding Normalium Z and uses its Z-Power, Shell Smash turns into Z-Shell Smash and eliminates any stat drops applied to the user, in addition to its usual effect as above.
