so I tested out today,
and actually it is too situational
I think I did it again once out of so many tries,
and MOST OF THE TIME it doesn't work.
I had to land at the right distance for it
to stay as a red combo ( the right distance where
5C will hit the fastest, I don't really know what is this specific distance)
considering
I think jin takes 9-10 frame to sheathe his sword
after the ice car. Maybe the A ice car would work better
because jin dont have the animation of sheathing his sword
but I didn't try this
I am not sure whether this will work as fatal or not,( need to calculate what's the stun period out of the 3rd hit of fatal combo then and make sure it's more than 9 frame for this to work)
but definitely it's risky and doesn't work everytime.
I guess I was just lucky that time. maybe RC or just reset
is a better bet than hoping it will still have a red combo normally
sorry for the misleading Hype
