Zaos would never admit it out loud but really was a bit rusty. Not to mention, Erean was really strong. He could make things easier for him by using magic, but that wouldn't be enough. He didn't want to prove a point by winning in a spar… he just wanted to get rid of the rustiness.
Before Erean could try to attack again, this time was Zaos who dashed forward. Erean strengthened his guard since Zaos was faster, but then he was preparing to counter-attack once the blocks the first swing since Zaos was smaller and lighter. However, he changed his mind and a horizontal cut aimed at his left side came. He heard the sound of the wind being cut, and he realized instantly that it was dangerous. So, he stepped backward again while he swung his sword downward, hitting Zaos's weapon and breaking his stance slightly.
