My bnbs off all starters.
Midscreen:
Meterless, no trait:
223, f3, j3, b23
123, j2, 123, b23
B113, b23
B3, j2, j2, 123, b23
F3, j2, 123, b23
Meterless, mid combo trait call:
223, j2, b2xxtrait, b23, rb, straight grapple
123, b2xxtrait, 123, b23, rb, straight grapple
113xxtrait, f23
Meterless, full trait
223, f3, j3, b23, rb, straight grapple
123, j2, 123, b23, rb, straight grapple
B3, j2, j2, 123, b23, rb, straight grapple
F3, j2, 123, b23, rb, straight grapple
1 bar, no trait:
223, f3, j2, 22xxmb grapple, nj2, 22.
123, j2, 12xxmb grapple, nj2, 22(working on this one to see if there's more options)
112xxmb up batarang, b3, j2, j2, b23
113xxmb grapple, b3, j3, b23
B113, f2xxmb grapple, b3, j2, b23
1 bar, full trait is essentially using the b23 ender and releasing bats in mb straight grapple into 22, b112, or b23. If its off 113 or b113, it ends with straight grapple, just no meter burn.

1 bar, trait call
223, 3xxtrait, 3xxup batarangmb, nj2, b23
123, 3xxtrait, 3xxup batarangmb, nj2, b23
Worth noting that you can replace nj2 with nj3 but it adds to the difficulty.
1 bar, full trait is just end the no trait combos with release bats into straight grapple. 2 bars is just mb straight grapple into ender of choice. Also, if you have no trait, but you want the two bar restand, you can do 22 after the nj2 following the mb up batarang.
