Power Release: The Spear of Striking Death Flight

Power Release: The Spear of Striking Death Flight (突き穿つ死翔の槍, Rikiton: Tsuki Ugatsu Shishou no Yari), is the largest and most powerful attack deliverable via the application of chakra to a weapon. It is the “attack that unleashes countless darts at the enemy” that is spoken of in the legends. Yūmei prepares to use this ability by backing one hundred meters away from his opponent, taking a crouching position on all fours, and accelerating through an approach run by dashing fifty meters before taking to the skies. He arches his back as if drawing a bow and hurls it towards the ground with all his might. It distorts space to create a "tapestry of action" that splits into numerous spearheads that pour down over the enemy.

It does not carry the property or concept of “always pierces the opponent’s heart”, but both the power and the area of effect are increased. Rather than dispatching a single foe with absolute accuracy, its focus as a technique is to attack the enemies together with the surrounding area in a carpet bombing fashion to cause massive destruction. Due to being hurled with a great amount of his energy, it cannot be dodged or blocked under normal circumstances. Even resilient bulwark or an agile body are not immune to its power, so Gáe Bolg will send the enemy horde flying.

Legend
The form and damage caused come close to Lugh's Brionac, but the having the ability "No matter how many times it is dodged, it will strike the enemy" makes it a weapon closer in nature to Odin's Gungnir. Koyoichi comments that it surpasses the original Gungnir in power, and that out of all the spears he knows, it is the only one able to pierce more than one layer of Rho Aias. The spear travels at mach two, and the farthest he has thrown it is forty kilometres.
