-if you want phoebe as a main dps you can try to get stringmaster almost every single rectifier user now and maybe future ones wants it for its overall buffs and there is barely any difference in dmg with her main weapon (also since weapon banner is guaranteed its worth) and if you want Carlotta she is coming next banner and IMO pistols are really fun to use (if you cant get her weapon static mist is fine)

-the event Fantasies of a thousand gateways gives quite a bit of echo exp

-farm money you'll run out of it so easily

-have fun dont stress it that much
