Niks hovered safely in the sky after catching up to the creature. Its attempt to clear the rubble it created didn't faze Niks as it sent smaller chunks flying at him and the bigger chunks were thrown backwards towards the buildings. There was no sight of the girl however, and Niks took it as a chance to agitate the creature and launched the Hex at the creature's scaly backside, taking a small moment so that his aim wouldn't hit any of the more armored part of its body. He has no idea how strong the effect would take hold on a creature of its size, although he knew that it wouldn't even felt the hex coming in contact with it, as much as he knew that it would ignore a splash from a glass of water.
Niks remained hovering where he was, just a small distance away from its reach and height. Roughly 14 feet high and 12 feet far.
