well i find that if you do
launch jump up heavy kick psy blade cancel into psy thrust then aim it up fowards or straight up (for dhc) you do alot more damage then you normally would.
you do 70 damage versus the normal 55 , and you can still dhc,
although with more hits you build more meter in the end of the match where it wouldn’t matter i think knowing that combo may be a big difference between winning and losing.
it’s supposed to go straight, it takes practice, and if you miss (they are too low to go foward) you can make a desperation down fowards version that otgs (the window is small) but does 69 damage or close to it.
