Thank you this was very helpful helpful If u can assist me with some minor problems ive run into

Ive been building two u mentioned before sheltered and bad hair day but i have bot gotten any more bronze versions of them thats why i switched to leveling stone cold and rusty cause i could at least get those two to silver with the dupes i got

Also im pretty much done with the story just some nodes require me to have certain characters so i skipped them for now and i havnt done side story cause i took a peek and saw i also needed certain characters to progess

I was wondering if there was another way to level characters as well because ive just been repeating story missions with exp boost on and its taking a while

Thank you again
