* Use the "Exp. Share" item: This item is found at the start of the game in your bag and it distributes experience points to all Pokémon in your party who are not the one who directly attacked.
* Use the "Lucky Egg" item: This item can be obtained from the Game Corner and increases the experience points earned by the Pokémon holding it.
* Battle with higher-level Pokémon: You'll earn more experience points by battling against Pokémon that are stronger than your own.
* Use the "Rare Candy" item: This item can be found in various locations and immediately levels up the Pokémon who consumes it by one level.
* Train in areas with lots of Pokémon: Certain areas in the game have a higher concentration of Pokémon, allowing you to level up your Pokémon faster.
* Use the "Poké Radar" to find chains: The Poké Radar, found in the Battle Frontier, can be used to find chains of wild Pokémon. Each chain gives a bonus to experience points earned.
Remember, even though you can't share experience directly, using these methods will help you level up your Pokémon more quickly and efficiently!
