Eruption is a Fire-type move with a maximum base power of 150 and 100% accuracy. The power of Eruption decreases as the user's HP decreases; it is strongest when the user has full health and weakest when the user is low on HP. Because of its variable power, Eruption is most effective when used by Pokémon with high speed or bulk that can maintain high HP for as long as possible. It hits all adjacent opponents in double or triple battles, making it a potent move for clearing the field. Eruption is noteworthy for being one of the strongest Fire-type moves in the game, particularly when paired with abilities or strategies that help the user stay at maximum HP, like healing moves or supportive teammates.
