For a month of playing, I feel like you could have probably accomplished more. Your team currently suffers from the beginner mistake of using whatever SSR himes they have, which is fine for like the first couple weeks when you're still getting things together but you've been playing for a month+?

I'm not sure what you have but some suggestions just based off your image.

Replace Shamash and Zephyrus for a full thunder team. Use a thunder atk eidolon, even R ones, they're easy to full break. Use the current event to get better thunder weapons.

You can make a starter light team with Mordred, Shamash, Dike (gem gatcha) and Urania (gem gatcha). Whatever other light himes you got. You seem to have several light weapons, hopefully they're not just R weapons.
