I'm stuck at chapter 14. I made some progress in chapter 15 but can't go much further because an evermore, even if it's evolved and enhanced, is not very useful if it is not stared up to the max level. The reason why I can't star up some SSR evermores is because I need items from chapter 16. I can't even get to chapter 16 because evermores that are missing a star are not enough to pass many levels in chapter 15. It all seems like a futile struggle and has made the game boring.
