After becoming Champion, the Wild Area truly opens up. Stronger Pokémon will appear, and new Max Raid Battles will become available. You can now access areas previously blocked by high-level Pokémon. Focus on collecting rare items, finding hidden Pokémon, and participating in 5-star and 6-star Max Raid Battles for valuable rewards like Ability Capsules, Mints, and rare TRs. It's also the best place to farm Watts for Rotom Bike upgrades and Wishing Pieces.
