Build (cry for) help 😭

I’m planning on pulling Bina when she comes out. I’m currently at 50-50 and have, like 150 pulls only.

I’m majorly f2p and for the first time invested in bp today to pull for Bina.

I have a c0 Lauma right now with zero refinement etherlite spindulette (?). I 100% want Bina to be on field ‘cause I really really just want to be able to play her.

I have never fully built any characters. In the sense that I only majorly look at main affixes and never the minor affixes when it comes to artifacts. My max damage ever was probably 50kish on a vvvv good and rare day.

If everything goes well, I will try to pull for Ineffa too. I have no 5 star weapons except for the primordial jade winged spear which I received on a standard banner I think?

But as of now (without considering Ineffa) I really really need a solid build for Bina and Lauma. I also have the Bp for this time, so technically one weapon from that too.

Please please recommend artifact sets and their best possible stats that are currently known for Lauma and Bina 😭 along with maybe team comps that help me keep Bina on field.

These are all the characters I have.
