'Erasing Presence' technique or skill was the one that he had been looking forward too, courtesy of the little thief he had captured from the Quick Hands organization.
As for how he managed to get his hands into this skill, we will have to go a bit back in time, when Eric arrived at the bar.
…
Eric had directly determined the presence and condition of the target the moment that he had entered the bar, and he was thinking about how to do this without attracting attention.
But who would have expected that the moment he set foot on this place he would become part of that stupid situation and became the center of attention for everyone in the bar.
Even more so after he had shown a bit of his strength and had brought that idiot down with a slap, breaking his neck in the process.
He could feel that his target seemed to have sensed his strength and became wary of him, but he still didn't react.
