First combo bok 1+2 into d3+4 isn't a true combo, they can tech back and block it or tech to the side and avoid it. You need to delay bok1+2 so it hit on the low wall slump to get the true follow up of d3+4. Also the optimal wall enders are ws142 if you theyre low on the wall, bok1+2>d3+4 if it was a higher ough wall splat, or (b14)b4df1+2(or knk3+4)
Thank you @yokaitamer9436 BOK 1+2 ~ D3+4 in the combo ender at the wall does the chip damage more and NO opponent can't tech roll or back immediately because BOK 1+2 at the wall splat causes opponent to face down on the floor leading us to hit him with D3+4 which is guaranteed. Also about the ender it's WS141 not ws142 which works as a follow-up for any TORNADO move like DF12, F3+4, B14KNK34, F4KNK34 etc.
Thank you @Arcanero for your comment. Yes. To break the hard floor we have many ways, I have displayed the explanation on the top of the combo inputs for each combo. For this specific hard floor break combo, we need two down moves, I have used CH UB3 twice, you can also use CH D2 twice or stomp twice while opponent down on the floor, once the hard floor breaks you can use many routes to wall carry in the basement1, I used a simple one.
