I started playing this game literally because of Cartethyia and Lupa trailers. Managed to pull both of them and just got Aero Rover yesterday but I don't know what the fuck I'm doing. I'm just winging it this whole time and the difficulty is starting to catch up to me. I don't have any 5 star weapons except for the story one and my echoes all are over the place.
What should I focus on? Septimont is kicking my ass.
