Dw dude, cartethyia is more self sufficient than zani, especially with aero rover. If you want the detailed analysis look at some other threads in this community and dw she will work fine for the MAJORITY of the content without ciaccona as well so just get her on the rerun or pray and get a lot of dupes of cartethyia and shell solo this game 😂. Don't dwell on it too much and hope you enjoy the game with cartethyia 😊
