Sylas took a breath and exhaled.
Despite the power of the punch, he realized several issues immediately. For one, his arm was throbbing as though he had just put it through a rigorous workout. He was certain that if he punched out with this same arm again, there would certainly be problems.
The second issue was that far more of his Aether was used up than what the technique denoted. It said that it should have cost just one Aether Unit, and yet he had used up as much as five just now, and it even felt like the technique wanted to take more, but he was just unable to sustain it.
However, Sylas had a feeling that even if he could give the technique more, he certainly shouldn't do it. That's because his body definitely couldn't withstand it. It didn't seem to be a matter of Constitution as the damage came from his Aether channels themselves. His Constitution alone couldn't seem to protect it.
