Going for the sky wasn't a safe choice because of that giant monster that could knock people away by flapping its wings or some other body parts.
As a means of caution, Angor kept his sequence of gravity activated while climbing so that he could run away from danger the moment he saw any.
Despite his effort, he was still sent away by a strong air current before he could see what caused it. Due to the gravity power, he did not crash down this time. After tumbling in the air for a while, he managed to regain his balance.
He looked up again and saw the same giant shadow looming over him. It seemed that this unknown monster that he couldn't see clearly was preventing him from going too high.
Was that some kind of wind spell?
Angor tried several more times, and every time, the strong wind would block his movement no matter how fast he flew.
