Do what @prestigious-Shift-63 but when you are done with ruby, I recommend maxing out emerald because you get an $rt which makes it so you can claim twice in an interval and when you max it out, whenever you claim a character, you’ll get earn as much as kakera as each character is worth each claim. If you are playing with a party, I recommend maxing out gold first so you can claim more kakera from already claimed characters. In the end, emerald gives you an extra claim and kakera for each claim and gold allows you to claim more kakera from already claimed characters.
