When this Pokémon enters battle, the terrain is changed to miasma for five turns or until replaced by another terrain.
If the user is holding Terrain Extender, this effect lasts for eight turns instead of five.
If multiple Pokémon with this ability, Electric Surge, Ghostly Surge, Grassy Surge, Misty Surge or Psychic Surge are sent out at the same time, the abilities will activate in order of Speed, respecting Trick Room. Each ability's terrain will cancel the previous terrain, and only the terrain summoned by the slowest of the Pokémon will stay.
