Betrayal [1]

Damien didn't even have the energy to stand up straight as his Void Essence wrapped around the dark material and turned it into essence for him to digest.

The second he finished casting the devour skill, his body collapsed to the floor. He didn't even bother to check what kind of benefits he received from the dark material. He didn't even think of the consequences that'd come with the fact that he devoured a portion of a higher existence. 

He had been holding on due to his sheer willpower and some unknown force that allowed him to keep his rationality after the soul attack, but he was still human. There was no way he'd be free from the side effects.

As the adrenaline rush wore off, a blood-curdling pain began to wreck his body. It was a level of pain he'd never experienced before. And when Damien was the person in question, it could be inferred how severe the pain was.
