The user covers the ground under everyone’s feet with mist for five turns. This protects Pokémon on the ground from status conditions.
Effect
For five turns, protects all Pokémon on the ground (i.e., not Flying, Levitating, holding an Air Balloon or under the effects of Magnet Rise or Telekinesis) from major status conditions and weakens Dragon moves used against them to 0.5× their power. Yawn will fail if used against a Pokémon on the ground during Misty Terrain, and any grounded Pokémon already made drowsy by Yawn will not fall asleep.
