How is my Nefer damage for a f2p build and....

..how much will Bina increase my damage by ....cause I really really like Bina but I'm not guaranteed ~127 pulls and also want Nicole

So in that sense I need a bit of help

Btw the team is C0R1 Nefer, C0R5(etherlight) Lauma, sac nahida

And Nefer Stats are 1378 atk 667 em 56.9/310
