The Withering Thrust was not a pure darkness spear technique.
It also involved concepts such as death, decay, wood and so on. It was a relatively more complicated technique to pull off for a pure wielder of darkness.
Fortunately, Ves had gained an artificial foundation in the withering curse from an enlightenment fruit, so he happened to be able to meet these troublesome requirements.
This was why the Withering Thrust was the most suitable technique for him and the Dark Apostle despite being way more complicated than many other techniques.
The Withering Thrust that the Dark Apostle just pulled off relied heavily on the Dark Tooth and Blinky to gain its power and structure.
Both of them constituted rather potent sources of power, so the threat posed by the Withering Thrust immediately caused alarm bells to ring in the Fiery Axe's mind!
