Electric Terrain is a Electric-type move that creates an electric terrain effect on the field, lasting five turns. This terrain affects Pokémon on the ground, increasing the power of their Electric-type moves by 30% and preventing them from falling asleep (including Rest and Yawn).
If a Pokémon is holding an Electric Seed while the field is Grassy Terrain, it consumes the Electric Seed and its Defense is increased by one stage.
Terrain Extender extends the longevity of the terrain from 5 turns to 8.
When a Pokémon with the Ability Electric Surge enters battle, Electric Terrain is automatically created which lasts for 5 turns.
