Whoosh!
Although Noel had swung his spear upwards in a similar fashion to Valyr, perhaps even a bit sloppier than the latter, the wave of dark energy that had been generated by the movement was at least five times as large than the one Valyr had generated with his skill.
Aside from that, as the wave continued to move, it continued to grow larger, at some point covering at least a third of Valyr's field of vision. With that, it was no surprise that Valyr felt a great amount of dread once he realized that the large wave Noel had sent out was heading in his direction, the wave emanating the feeling that it devoured everything that came across its path and assimilated it with the darkness.
Fortunately, just as the large wave was only around 50 meters away from where Valyr stood, the wave of dark energy quickly dissipated into thin air, prompting him to wonder if the hundred meter tall waves of dark energy had almost come close to enveloping him in the first place.
