After the buffalo landed, it wasn't even a matter of time before it was the pillar's turn.
As soon as he heard the thumping sound of the buffalo's landing, Nil activated the tiny amount of mana he had gotten control over during the fall. He used the mana to control the metal right under him and launched himself off the pillar.
In theory, if he did it fast enough, he could offset the speed of his descent and arrive at the ground with low enough momentum to survive the landing.
It was just that he needed to launch himself with incredible speed in order to reach a speed similar to the falling pillar. It was just that Nil wasn't very specialized in making his magic move quickly. His traps relied on mechanical functions to exert the force and velocity they did. And Nil didn't have enough time or mana to try and imitate Sharp Rain's speed on a flat surface.
The only thing he could do was take inspiration from the explosive speed with which Scrael could use her magic.
