« Spiral, ready!"
Caladbolg: The Rainbow Sword (虹霓剣, Kōgei-ken?) is the magic sword of Fergus mac Róich. Also given the appellations of Spiral Rainbow Sword (螺旋虹霓剣, Rasen Kōgei-ken?) and Spiral Sword (螺旋剣, Rasen-ken?), it is a high-power and wide-range attack that makes even destruction of the landscape possible. It is the natural enemy of Cú Chulainn due to him having a geas that makes it his duty to be defeated once by the sword so long as it is wielded by someone who is Ulster-born. It is the prototype of many magic and holy swords of later ages, including Excalibur Galatine, and thought to be the same sword as Caledfwlch from Welsh Mythology, possibly making it the prototype of Excalibur as well. The sword changes appearance as Saber goes through Ascension, becoming more drill-like.
It is noted in legends that it activates as a sword of a light, unleashing a "sword-shimmer" that "stretches from the magic sword like a rainbow", allowing it to cleanly slice off the top of hills at full power. He used it as such when taking out his rage at being unable to take his revenge, showing its fearsome power by slicing through the tops of three hills. Despite such usage, its true aspects when wielded as a Noble Phantasm are more pronounced towards landscape destruction. Described as a "no-questions-asked great attack that breaks the earth", the Heaven and Earth Sky Great Rotation, he plunges it into the earth and causes a great eruption around the enemy.
Caladbolg II: The Fake Spiral Sword (偽・螺旋剣, Gi Rasen-ken?, localized as "Fake Helix Sword") is a modified version of the original Caladbolg using Reinforcement. Archer encountered the original sword at some point during his life, adding it to the numerous Noble Phantasms stored in Unlimited Blade Works and allowing him to modify it to improve its function as an arrow and suit his fighting style. He projects it to be used as an arrow rather than a sword, with the improvements aimed to make use of it as an A-rank Broken Phantasm. He chants the first line of Unlimited Blade Works' incantation before firing it and, despite being renamed with the "II", he still only chants "Caladbolg" to activate it. When utilized as a close-combat weapon, he thrusts it to pierce his opponent.
The blade of the sword coils into a spiral that can penetrate any target by creating a twisting distortion in space when fired. When fired at Caster, it is powerful enough to easily break through her magical defenses simply as an aftereffect of it being purposely fired at an area far away from her. Shirou believes that, even if she had tried to teleport away from the attack, she would have simply been twisted along with the space as well. After being intercepted by Berserker, it creates a large explosion capable of razing a cemetery and engulfing it in flames.
Caladbolg III: The Fake-Fake Spiral Sword (偽・偽・螺旋剣, Gi Gi Rasen-ken?) is a deteriorated version of Caladbolg II utilized by Chloe von Einzbern. Releasing its True Name strengthens it and allows it to pierce everything by twisting space.
Fergus My Love Edit
Fergus My Love: My Dear Rainbow Sword (愛しき人の虹霓剣, Itoshiki Hito no Kōgei-ken?) is one of Medb's Noble Phantasms where she temporarily summons the magic sword Caladbolg, the Noble Phantasm of Fergus mac Róich. With a lovely swing, she releases the sword of a rainbow-like light, the Heaven and Earth Sky Great Rotation, as a ranged attack.
Fergus, My Good-Looking Brave Edit
Fergus, My Good-Looking Brave: My Dear Boyfriend's Rainbow Sword (愛しきカレの虹霓剣, Itoshiki kare no kōgei ken?) is a Noble Phantasm of Medb in her swimsuit. Employing the magic sword Caladbolg (the Noble Phantasm of the hero Fergus, one of her lovers in her previous life) as a weapon. She can perform the release of True Name as if a matter of course, but it seems that she is demonstrating some self-restraint at this occasion. Even Queen Medb - no, exactly because she is Queen Medb that there is no way she would cause an earthquake in a wonderful resort spot.
Nobody knows if, just like when she is a Rider, she materialized this due to the properties of her anecdotes and legends about "taking possession of heroes" or if she simply borrowed it from the Fergus at Chaldea. As expected, its power have decreased compared to when Fergus himself uses it, but its flexibility, adaptability have improved in exchange. A rainbow veil is instantly deployed just by shaking it cutely with a "hey". Enemy soldiers that become Medb's targets will probably be arrested in a rainbow veil and rendered powerless inside that light of ecstasy, without understanding a thing about what happened.
Her weapon of choice in this work. Release of True Name is not performed.
Hirokazu Koyama is the weapon designer for Caladbolg II.
Gilgamesh is shown using Caladbolg from the Gate of Babylon on Lancer in the Fate route of the Fate/stay night anime, but it uses the design of Caladbolg II due to being developed before the original Caladbolg appeared in Fate/Grand Order.

He was kept from revealing his true prowess due the fact Cú Chulainn was in Ulster, but still reached the point where he was one step away from slaying King Conchobar.
Level 5 Bond
Due the pledge (geis) exchanged with Cú Chulainn at this occasion, he will achieve victory almost unconditionally in case there is a rematch with him.

His wish for the Holy Grail is to "once again "get along" together with my wife and Medb".
Get along. Together.**
By the way, his wife is a goddess of the forest-- a Divine Spirit. There are not that many humans who can compare to his peerlessness!
*by the way, the original term can also be translated as "endless sexual stamina"
**this is actually a pun, as it can also be understood that he wants a three-way with the two of them.
***don't look at me! It was like that in the original!!
****I tried to find a good synonym for rainbow to put here, but it didn't work out. I'm leaving like this then.

Caladbolg is the demonic sword wielded by the Irish hero Fergus mac Róich in Celtic mythology. The version that Archer projects has been altered to improve its function as an arrow.
In the legends, Fergus mac Róich was the former king of Ulster and foster-father of the hero Cú Chulainn. However, he was tricked out of his kingship, and later allied with Connacht, an enemy of Ulster. During the decisive battle between Connacht and Ulster, Fergus was able to corner the enemy king who had betrayed him, but was prevented from killing him. It is said that he redirected his rage at this turn of events upon three hills, using Caladbolg to blast their tops clean off.
Cú Chulainn is affected by a geis that makes it his duty to be defeated once by the sword so long as the wielder is Ulster-born. For that reason, it could be said to be his natural enemy.
Also, there is a theory that the Caladbolg from Celtic mythology is the same sword as the Caledfwlch from Welsh mythology, making it a prototype of Excalibur.

The Reborn Sword of Victory [Noble Phantasm]
Gawain's Anti-Army Noble Phantasm. A Pseudo-Sun is contained in the hilt.
A holy sword in King Arthur's legends, it is the sister sword to Excalibur. If Excalibur is a sword that destroys castles, this sword destroys the enemy army.
If King Arthur's holy sword collects the light of the stars, Sir Gawain's holy sword represents the rays of heat from the sun.
Unlike Excalibur's centralized attack, Galatine is a broad wave, radiation-type attack that completely annihilates the enemy army. Like Excalibur, the original owner is a Maiden of the Lake. Hidden in Excalibur's shadow, it's a holy sword rarely mentioned in the legends.
In the remaining legends, it is similar to its owner, Gawain, and shows its greatest power at noon, the unsurpassed shaprness of the edge is said to become visible. That sharpness sliced clean through the shield and chainmail of the enemy, the Saracen soldier Priamus.
As Arthur has the providence of the night (Alto, Artemis, the pedigree of the goddess of the moon), Gawain is the knight who receives the blessing of the sun.
That special characteristic is reflected in the Noble Phantasm, which is like the rays of heat from the sun. Caladbolg is the prototype of Galatine, like a long rainbow, and cleanly sliced off the top of a hill with its full power.
It was a sword of light that stretched from the magic sword like a rainbow. Galatine is similar; with a motion like drawing a sword, and the pseudo sun inside and the magical energy put into it, the attack extends as far as it is possible to visualize the blade of the sword.
That is to say...about 13 kilometers or so.

本来の持ち主はエクスカリバーと同じく、湖の乙女である。伝承ではエクスカリバーの影に隠れ、 多くを 語られる事のない聖剣だった。
アーサーが夜(アル卜、アルテミス系の、月の女神 の名前の系譜なので)の守りであるのに対し、ガウエ ィンは太陽の恩恵を受ける騎士である。その特性を色濃く反映した彼の宝具は太陽の熱線を顕して いる。
ガラティーンの原型であるカラドボルグは、虹のように長く、丘の頂天を斬り落とすほどの威力を 持った どされる。剣光を虹のように伸ばした魔剣だった。
ガラティーンもこれと同じく、抜刀し、魔力をこめると内部の疑似太陽が運動し、剣の刀身を可視 できる 範囲まで伸ばすという。
