Gungnir: Declaration of the Great God (大神宣言, Gunguniru?) is the spear wielded by Odin in Norse Mythology. It is said to be a prototype of Gáe Bolg, with the technique Soaring Spear that Strikes with Death being extremely close to Gungnir. Gungnir was capable of shattering the "Sword of the Sun" Gram wielded by Sigmund, needing to be reforged after its destruction.
Gungnir: Declaration of the Great God (Fake)
Gungnir: Declaration of the Great God (Fake) (偽・大神宣言, Gunguniru?) is a degraded version of Gungnir, bestowed to the Valkyries by Odin and wielded by them as Noble Phantasms. If thrown after the True Name is released, a sure-hit function will activate.

Noble Phantasm: B
Once Ireland was called Erin, which means "green" in Gaelic. In this land named after its abundant greenery, there was a boy with great talent. His name was Sétanta. It is said that his father was the sun god Lugh and his mother was royalty. One day, he accidentally killed the guard dog protecting the house of master blacksmith Culann. Sétanta alone strangled to death "Culann's savage dog" that was well-known to have the strength of ten men. In order to compensate for this deed, for a while he himself would carry out the duties of a guard dog. Consequently, all began to call the boy "Culann's savage dog" i.e. Cú Chulainn.
In time, the grown Cú Chulainn was accepted as a member of the famous Akaeda Knights. His actions after that rendered him unmatched. He went to the "Land of Shadows" to fulfill his own love; there with incredible magic and unrivaled demonic spearmanship, he acquired Gáe Bolg. Cú Chulainn had become invincible but the sun still set. At a young age, a close Druid's prophecy said "in exchange for glorious deeds of valor, his life would be short" and accepting such a fate, he smiled and laughed.
In his final battle Cú Chulainn battled furiously and died pierced by his own magical spear. A crow landed on the shoulder of his standing corpse in his death. It is said that it was the incarnation of the witch Morrigan who continued to give him her unrequited love.
Naturally by his own beliefs, he prefers to fight with his full power as a warrior. However, due to the Command Spell of his Master Kotomine "Fight with everyone, then withdraw," he was commanded to involuntarily perform reconnaissance missions. Even in the middle of his first battle with EMIYA, he showed decisive action by leaving the battle to kill Emiya Shirou whom he recognized to have witnessed it. The withdrawal was also very skilled, giving the appearance of realizing that the situation was unfavorable. Contrary to his legendary battle prowess, Cú Chulainn's fighting in the Fifth Holy Grail War was extremely limited.
Magic Resistance: C
Cú Chulainn holds a Magic Resistance of Rank C. Aria of two verses and below are cancelled, but beyond that High Thaumaturgy and Greater Rituals cannot even be defended against. That said, confronting a Servant of his superior speed (Agility A), finding the opportunity to use large-scale magecraft is next to impossible. Also, considerable skill is required to successfully "hit" him with the invoked magecraft. Judging from these factors, in situations of close combat, Cú Chulainn may have a "necessary and sufficient" rank of Magic Resistance.
In addition, as depicted in legend, he himself learned magecraft (18 Original Runes) in the "Land of Shadows", taking pride in having the skill and knowledge to qualify for Caster class. Even in a scene of the story, he sees through the presence of Medusa's Blood Fort Andromeda at a glance, considers the situation, and makes the decision not to destroy it. Cú Chulainn is not just a reckless warrior.
Battle Continuation: A
Legend tells that the dying Cú Chulainn tied himself to a tree before taking his last breath. For he who possesses such a legend, the dying struggle is particularly fierce. Even in a hopeless battle, Cú Chulainn was still able to demonstrate astonishing tenacity, delaying Gilgamesh for half a day.
Against Emiya who dextrously fended off his spear thrusts, Cú Chulainn countered with an unyielding fighting spirit.
The ability to withdraw from the battlefield in the midst of combat. Having been commanded to go on reconnaissance missions by his Master Kotomine, it can be said that this ability was fully demonstrated. From the start, Cú Chulainn excelled in seeing through battle situations, and had the responsibility to wage war and withdraw repeatedly from all the Servants.
Cú Chulainn obtained 18 Runes from his studies with Scáthach (Norse Runes), appropriately using them to respond in different situations. It is said that among these runes, one with the purpose of searching existed. It was the ability that supported his elusive actions during the Holy Grail War.
Protection from Arrows: B
Ability to deal with projectiles. This is a power Cu Chulainn was born with. It's said that it's possible for him to avoid any long range attack if he has made visual confirmation of his opponent. He can deal with most projectiles even in conditions where the opponent cannot be visually seen. Even if the battle with Hasan Sabbaha, he cancelled the throwing swords hurled from the darkness. As long as the attack is a thrown type, he can avoid even Noble Phantasms, but he can't gain the effects of this protection with respect to wide range attack types where the attack range of the weapon explodes on impact, or a direct attack by a weapon that has simply long reach.
The circumstances behind Cú Chulainn's great divinity is his father's existence. His father was Lugh, the god who governed over the sun, a member of the Danann divine family in Celtic Mythology. As a demigod whose father was an almighty god who possessed every skill such as knowledge, techniques and magic, and whose mother was Deichtine, younger sister of King Conchobar, he exhibited superior talent from birth. Boasting supernatural ability that separated him from ordinary people from a young age, in his training in the Land of Shadows, he received the original runes and terrible magic spear Gaé Bolg from Scáthach. Truly, he was a man predestined to become a hero. In Ireland, poetry and statues praising Cú Chulainn still remain to this day.
Gáe Bolg: Spear of Piercing Barbed Death
Maximum targets: 1
While this is a technique employing Gáe Bolg as a melee attack, it is originally a magic spear for throwing. With a technique that reverses the meaning of "cause and effect" in the order of things, the "result" that "the heart of the opponent has been pierced" is created earlier than the moment it is thrust. Accordingly, the "cause" that "the lance has pierced through the heart" is generated from it later. Without a great deal of luck (like Artoria), it can be said that this is a technique that determines "if it is released, the opponent is dead." However, against Servants like Heracles who can move even when their heart is destroyed, there is a small disadvantage. Compared to the Spear of Striking Death Flight, both the range of effectiveness and the destructive power are weakened. However, it is worth mentioning that "the magical energy cost is low." For having such a strong effect as "almost certainly will destroy the enemy's heart," without the need of a terrible amount of magical power, it becomes an excellent Noble Phantasm of extraordinary usability.
Gae Bolg: Striking Death Flight
Maximum Targets: 50 People
The largest and most powerful attack delivered using Gae Bolg. The “attack that unleashes countless darts at the enemy” which legends speak of is Gae Bolg – Striking Death Flight. After accelerating through an approach run, Cú Chulainn takes to the skies and activates Striking Death Flight by hurling it towards the ground with all his might.
Different from Gae Bolg – Piercing Death Thorn, Striking Death Flight does not carry the property or concept of “always pierces the opponent’s heart”, but compared to Piercing Death Thorn, both power and area of effect are increased (intense consumption of Magic Energy). It is a technique that attacks the enemies together with the surrounding area, in a carpet bombing fashion. Even resilient bulwark or agile body are not immune to the power of Striking Death Flight; Gae Bolg will send the enemy horde flying. In legend, the demonic spear is said to split into 30 and pour down over the enemy, but it seems the number has increased after Cú Chulainn became a Heroic Spirit. During the battle with Emiya, Emiya spoke of Striking Death Flight “exceeding the original, Gungnir – Declaration of the Great God”.
