Since I can aim the spires at my will, I can create a spire directly towards the opponent from front at a forward slanting angle and as well as create a spire to erupt from behind him which is also at a slanting angle aimed towards him leaving him little to no chance to escape away from the spire erupting from behind him as he is focused on the one from his front.
I can also make all the spires to erupt around the opponent in such a way that they converge towards the opponent as they erupt from all his side.
if the opponent is standing close to an earth structure say an earthen pillar, I can directly make a spire to erupt from behind his back, out of the earthen pillar making a surpise attack.
The jutsu itself has up to long range reach, meaning even if escapes the jutsu, as long as he is the line of the jutsu I can get him. further as I can create up to 5 spires, I can also make to erupt at various converging angles towatds the opponent making it difficult for him to escape or evade.
