All attacks had a stun effect, but the amount differed depending on the attack. For example, skills like Dragon Tooth had a stun that could be counted in seconds and were clearly pointed out in the skill description. The majority of skills didn't mention a stun effect because the hitstun was pretty much instantaneous. It depended on the player's experience to seize it.
The difference between normal players and experts were clearly reflected in places like these.
Why were experts able to complete combos using a certain chain of moves, while normal players were always easily interrupted by experts using the same chain of moves? It was because experts had a good grasp of the skill's rhythm. Every time an attack hit, they would always be on point. In theory, true combos that couldn't be broken existed, but they were too too difficult to perform. No matter how great a player was, the player could only try his best. It wasn't possible to grasp every attack perfectly 100% of the time.
