FYI:
So I'm pretty sure the forms you must master to become a Swordmaster using traditional Chinese or, to be non-specific, Asian martial arts are thrust, lift, point, cut, chop, and sweep. "Parry"? I'm pretty sure that's a French term and it's a blocking maneuver used primarily (or maybe even exclusively) in Fencing. Actually, there are like seven or eight blocking maneuvers which are considered parries. Or maybe all blocking maneuvers are parries in Fencing. It's been twenty five years since I took a class on Fencing, and I could be wrong about the particulars, but it's definitely not a word that should be used to describe a blocking maneuver in a duel between Sokka and Piandao. If Sokka or Piandao or Zuko or Jet block their opponent's move, just use "block". I know it's not very fancy but it's always best to keep it simple when you're describing fight scenes but have no true working knowledge of the martial arts or sword forms. Reading something along the lines of "Sokka dodged and parried..." seems woefully out of place.
