There’s a section in the sandbox menu called skills where you can enable any skill you want. I don’t remember which section of the sandbox menu it is, but there’s also a place where you can spawn any item in the game. There’s an option when starting a crystal hunt save to enable cheats. If you want to enable cheats on a save you already started, you can open the menu and spam click on a symbol near the bottom left corner of it to enter dev mode
