hi im new but does anyone know, a good follow up attacks when oppotent side turned. And how to get gurenteed damage from a up coming hit like jackes 3 p if blocked with jef. let me know thanks

 

4p,k ender>6643p

Setup:
-put opponent on ch
-put opponent to techroll
-if your follow up produces a normal hit then it's meaty.

Start with most ending parts of a combo and test them out.
