chaos guide should be helpful for you in this case. Amira should give you the same path and the only thing you can miss are the legendary smith, but you should think that there is one of them in every dungeon (so everything that is not a city) in the game.
In my opinion Yamatai should be one of your first destination in order to unlock the job that let you open gold chest, so you don't need to backtrack to get the gold chest you see during your adventure
Yeah I already did Yamatai, I'm currently cross-checking japanese wiki and this guide to see which progression is the best, there's some differences but I guess because it's the nature of "free roam", I'll use the notepad guide since it won't spoil the plot outline unlike the JP wiki.
Although I am confused by this line:
"Hades questline reaper and white rabbit, forbidden ghost race, forbidden beast race, forbidden chimera race
snow continent Ilias temple ruins hard area and extremely hard boss, pandora chests
4 main city quests story progression gives forbidden classes and races easy difficulty"
why is the guide telling me to go to illias temple ruins when it's a hard area in the beginning
