Hi! Thank you very much for your message, I’m glad you like the game :)
I’ll explain everything you need to know to break rocks, but be aware that it may contain spoilers since you need to have completed a large part of the game:
- You need to accept the mission in Kanto, Goron Cave (Route 15).
- Once you finish the Pokémon League, collect the 5 Lithic Stones and head to the Apacheta on Route 45.
- Complete the 5 Dojos of the 3rd Region and go to Marble City, where a fisherman will give you an item.
- Take that item back to Kanto, Goron Cave (Route 15), and you’ll learn how to break rocks!
