I did however mention that he had set the distance to precisely time the arrow effects going off though, and it has previously taken at least a few feet for them to activate. In addition, since Cruallassar has tried on most previous occasions to stay out of Shashous's reach, there is no reason to believe he would get that close now, even with the extra few feet provided by the net. However, that is a secondary point. I still need clarification on exactly what happened, within reach or not.
