When chasing the girl in the white cloak, there will be several hot spots in the woods. Whenever a hot spot appears on a log or a piece of wood, use it. To do this you must fight off the king's men and escape several times.
You must take down your opponent multiple times and recover by evading the attacks when your strength is low. Watch your energy meter and stop swinging when you are low. Look for the throws and duck while recovering.
