Flavor TextThe user covers the ground under everyone’s feet with noxious fog for five turns. This damages Pokémon on the ground a little every turn.
The user summons a noxious, virulent haze that settles on the ground around the battler's feet. Inhaling the miasmatic air damages all Pokémon that are not Poison- or Steel-types, and also increases those Pokémon's vulnerability to poisoning.
For five turns, damages all non-Poison or Steel Pokémon on the ground (i.e., not Flying, Levitating, holding an Air Balloon or under the effects of Magnet Rise or Telekinesis) for 1/16 their max HP at the end of each turn and strengthens the Poison moves of grounded Pokémon to 1.3× their power. Poisoned and badly poisoned Pokémon take double the normal amount of poison damage at the end of each turn. Pokémon with Immunity, Magic Guard, and Poison Heal are immune to the end-of-turn damage, and Poison Heal Pokémon that are poisoned recover double the normal amount of health at the end of each turn.
If the user is holding Terrain Extender, this effect lasts for eight turns instead of five.
Defog removes this effect from the field.
