How to get it
- The shop and selected event rewards offer Max Mushrooms. Some progression rewards can also include one.
How to use it
- Activate it when your group is ready for Max Battles. The standard effect lasts 30 minutes.
- The timer continues between battles, so prepare your team and particle supply first.
Worth knowing
Additional mushrooms add duration; the damage multiplier remains 2×.
This boost does not supply Max Particles, upgrade Max Moves, or apply to ordinary Gym raids.
Damage helps, but it does not replace a prepared team
Max Battles become much more dangerous when the boss reaches its desperate state. Extra damage can help your group finish sooner, but the mushroom does not make your Pokémon immune to incoming attacks.
Unlike ordinary raids, you cannot bring in a fresh replacement team after all three of your Max Battle Pokémon faint. Prepare suitable attackers and any supporting Max Guard or Max Spirit roles before activating the timer. Purified Gems cannot remove a Max boss’s desperate state.
