Max Mushrooms

The Max Mushroom is an item that temporarily doubles all damage that your Dynamax and Gigantamax Pokémon deal in Max Battles. You can use multiple Max Mushrooms consecutively to increase the effect’s duration, but doing so will not increase the damage multiplier.

You can use a Max Mushroom from your Item Bag while you’re in a Max Battle lobby. You can also see whether other Trainers in the lobby have activated Max Mushrooms.
