if you defence while doing rush attack the character do the animation of it getting damaged (without loosing HP) after that each time you rush attack (and not defence while doing it)you get the animation of you being damaged in the end of it

First thing first, you get stun and will have the "damaged" animation if you miss your Rush attack and didn't touch the enemy.

Is that you are doing? (and everything is normal)

Or is it something else?

well you are right, that was what i'm doing, but i realised something else, when you rush attack and damage your opponent and go through the enemy I still get the stun animation

All right, I'll check that  wink
