When they saw Enaxx make four copies of himself, the first thought they had was it had to be some type of illusion. The warriors had heard of techniques that had been used that would allow a person to appear as if they had copied themselves.
Maybe if an individual had a vast amount of Qi, they could create clone-like afterimages with their visual Qi. However, with both of these things, it would happen during a technique with much movement, and maybe the image in front of them wouldn't be as fluid.
Yet, each of the copies of Enaxx were moving of their own free will. They even stood with different gestures and different actions, and there wasn't even a break in their body.
"Oh, are you being polite, or did you want us to attack first?" Enaxx said as he waved his hand, and a sharp wind strike went through the air.
Immediately, one of the warriors swung their swords, cutting right through the magic and breaking it with their Qi.
