Clear Smog inflicts damage and resets all stat levels of the target to 0; unlike Haze, this move only hits one target rather than affecting every Pokémon on the field. This effect does not work if the target is unaffected by the attack because of type immunity, protection, or is behind a substitute.
Clear Smog bypasses accuracy checks to always hit, unless the target is in the semi-invulnerable turn of a move such as Dig or Fly.
The user attacks by throwing a clump of special mud. All stat changes are returned to normal.
