The user electrifies the ground under everyone’s feet for five turns. Pokémon on the ground no longer fall asleep.
For five turns, prevents all Pokémon on the ground (i.e., not Flying, Levitating, holding an Air Balloon or under the effects of Magnet Rise or Telekinesis) from sleeping and strengthens their Electric moves to 1.3× their power. Yawn will fail if used against a Pokémon on the ground during Electric Terrain, and any grounded Pokémon already made drowsy by Yawn will not fall asleep.
If the user is holding Terrain Extender, this effect lasts for eight turns instead of five.
