A combo is a chain of hits that if u hit the first one, u hit them all.

1.-If u get hit, its no more a combo
2.-If u miss even 1 hit, its no more a combo
3.-If the enemy touches ground and u let him get up, is no more a combo
4.-If the enemy touches ground and he uses ukemi, is no more a combo
5.-If the enemy didnt touch ground but it takes u too long to hit again, its no more a combo

I know all you wanted was to do the challenge thing, but if u somehow choose to do it the old fashion skills needed way, there u go.
