Changes in the Clouds

When he is wounded in Divine Comprehension, his energy leaks and when an injury goes deep, it touches the soul

Now, he has a form. 

A body. It limited him. 

But it also protects him in a way. It gave him the first barrier 

The pain would not directly reach the soul. 

There is the body first. 

You had to break down the physique that he has first before you could attack the soul. 

This is the difference between the body of an Energy Disperse Stage realm and the body that Azief had crafted again. 

In the body of the Energy Disperse stage realm, you possess great physical prowess but vulnerable to soul attack. 

Even Azief when he has the perfect physique in Energy Disperse Stage and could fight a whole realm above him, he is still vulnerable to soul attack. 

Even if his body would not rot or destroyed by normal means, if someone is adept at manipulating the soul, he could not defend himself
