"Precognition?" Unsurprisingly, Valyr began to look at Jekyll with disbelief in response to those words. "Is that even possible with the skill?"
As far as what he and Jekyll had discussed and confirmed, [Warrior's Eyes of Slaughter], as well as the previous versions the man had given him, gave him the ability to pinpoint weak spots on anything he laid his eyes upon.
Aside from that, the skill also allowed him to give off an aura that would greatly intimidate those that were weaker than him, while also catching the attention of those that were stronger than him.
Although he did not know how the second part of the skill actually worked, Valyr had a feeling that it had something to do with how the eyes made it seem like he was a predator gazing at its prey.
