Destroy Rocks
Make sure that you destroy rocks whenever they appear during battle as there is a chance they will drop AHP which is something you need in the late game for purchasing 'Homemade Cookies'. These cookies cost 30 AHP each and give +20 to whichever character you choose. You can purchase three cookies, and they are a big help for the True endings.
