How to Increase Level Cap in Pokemon Masters
Your Pokemon can grow to level 30 normally, but you can increase it to 45 by completing a quest. You have to get the first badge and take the Special Training Mission: Battle Techniques quest from Professor Bellis. After that, you'll get one more mission: Reach Past your Limits. Completing this will allow you the option of raising level caps.
You'll need certain items to raise the level cap, and higher level unlocks require rarer items. Some Sync Pairs will use less resources depending on their rarity. To get the final level cap unlock, you'll also need Gym Leader Notes. Each Sync Pair will require different items, so be sure to check which ones you need.
