Interactables
So I've been trying to do b23 interactable bounce b3 j.3 f213 zod charge but it hasn't been working.
But 12/22 bounce (same combo) does 38%.
The bounce misses from b12
The bounce misses from 22 when you aren't facing the same way (missed when both of zods' chests or backs aren't facing the player)
and from b23 bounce the most damage I could get was 35%
****At the end of a combo I'd recommend ending with 112. I know I wrote 123 for most of them because 123 does 10% and 112 does 9% but after scaling in some combos 112 does 1% more*****
