2. Use Exp. Share. The Exp. Share is an item that allows all of your Pokémon in your party to gain experience, even if they don't participate in battle. This can be a great way to level up your weaker Pokémon.
3. Use Rare Candies. Rare Candies are items that can be used to instantly level up your Pokémon by one level. These are relatively rare, so use them sparingly.
4. Take advantage of the Day Care. You can leave your Pokémon at the Day Care to be cared for by the staff, and they will gain experience over time.
5. Battle other trainers. Battling other trainers is a great way to level up your Pokémon and earn rewards, such as money and items.
6. Complete Quests Certain questlines reward a large number of experience points for single battles.
Here are some additional tips for leveling up your Pokémon quickly:
- Use a Pokémon with a high Attack stat or Special Attack stat to make your battles faster and easier.
- Use a Pokémon with the ability "Experience Boost." This ability increases the experience points your Pokemon earns in battles.
- Play the game on the second or third fastest Speed. While time may not be moving any faster, the battles and cutscenes will speed up allowing your battles to go by much quicker. Just make sure to turn it back to regular speed if you ever have a difficult trainer battle as you won't have as much time to react to incoming attacks.
