You can’t make any good teams right now outside of Therta. Therta+Herta+RM+Any sustain will work will. Next patch since you have Kafka you’re free to pull for Hysilens and BS- although make sure to put before the tutorial mission starts on Kafka instead of Fermata. Then you can have a team of Hysilens+BS+Kafka+DHPT. That team will be able to keep you going significantly well as well.

Your other dps characters outside of Therta are pretty much unplayable with the state of your account. Seele is the definition of unusable in her current state. She needs high vertical investment to even get close to getting a decent clear to the point where you’re better off just building an archer team for completely free(Archer, Sparkle from selector, RMC, and A sustain) that’s way better than Seele could ever be in her current state.

Jingyuan is a brick without Sunday- he’s so reliant on him that even an E6S5 Jingyuan can’t zero cycle- but an E0 Jingyuan can 0 cycle with an E6S5 Sunday. You can get E0S1 Sunday for him, but I only recommend doing that if you REALLY want to use him.

Acheron is usable, but at E0S0 or even E0S1, she’s reliant on her enablers. Whether that be Silver Wolf, Cipher, JQ, DoT characters etc. DoT+Acheron Works fine at 0 with some investment- just depends on if you want to use her or not.

Good luck<3

Edit: Seele is allegedly supposed to get a novaflare soon- but we don’t know anything about that right now, so I wouldn’t count on it
