@chendu What do you mean "you'll understand"? I already read the novels and because of your comment just now I went back to look at chapter 66 again(the one that's relevant in this case), and I don't see what I might have missed.
Nothing in the chapter contradicts what i said, even less so the author's note at the end of it.
So you're comment was pointless and what I said is still correct. I was explaining the "Non-lethal hit"(also known as "Blunt-Edge Strike" in other translations) skill.
(By the way, the Author's Note of that chapter isn't even about the Meteor Kick, but instead about an earlier part of the fight. It's about how the laws of physics are left behind by Ruphas, and thus I guess it does have a little to do with the rest of the battle too, but it was only mentioned in the chapter in that earlier part.)
