Class Saber (クラス・セイバー, Seibā?), Knight of the Sword (剣の騎士?) and Heroic Spirit of the Sword (剣士の英霊?), is one of the Three Knight Classes among the seven standard Servant classes summoned for the Holy Grail War.
Servants placed within this class are agile and powerful melee warriors adept at swordsmanship, boasting high ratings in all categories, and they are often heroes from the Age of Gods when magecraft was still commonplace. The qualifying conditions require the Heroic Spirits to have legends as knights of the sword, and it is the class that requires the highest levels of attributes in all but the Magic attribute. It is possible for the status qualifications to be bypassed in special circumstances, such as through Nero Claudius's Imperial Privilege. Toyotomi Hideyoshi's Noble Phantasm Sword Hunt qualifies him as an extremely rare Saber without qualities distinctive of the class. Compatible Heroic Spirits usually excel in delivering powerful burst attacks.
Skills and characteristics
The standard opinion is that the Saber Class is the best of the seven classes and the strongest of the Servants, said to have made it to the final battle in the first four Fuyuki wars. They will generally have an overwhelming advantage over Caster-class Servants who uses magecraft as their main offensive ability due to their Magic Resistance Skill. The weakness of the class is its straightforwardness in battle, only able to attack the enemy with their sword while unable to resort to other tactics like the Presence Concealment of the Assassin Class. Among the many Heroic Spirits that can be summoned to fight in a Holy Grail War, King Arthur is widely considered to be the strongest Saber class servant.
Within Fate/Grand Order, NPC Servants are represented by a generic figure resembling the Tarot Card.
- Servants marked with ‡ are also able to be summoned by Ritsuka Fujimaru in the Grand Orders.
- Servants marked with † are also contracted to Hakuno Kishinami in the world of Fate/EXTELLA.
- Servants marked with ⁜ are those who change class mid-story but do not display characteristics substantially different from the original class.
Two variations of the class has been shown with names and abilities based on the Roman gods.
|Class Name||True Name||War||Master|
|Saber Mars||Attilaight Cell||Moon Holy Grail War||Hakuno Kishinami|
|Saber Venus||Nero Claudius||Moon Holy Grail War||Hakuno Kishinami|

« Since Saber is trained in traditional swordsmanship, I decided to go with the image of a knight dressed in a full set of European plate armor. The pose is also an archetypical knight's salute. I didn't want the armor model to get too clunky, so I didn't stay true to Saber's origins as stated in the official character profile. Instead, I took my inspiration from the simpler Gothic style armor of 15th-century Germany. »

 Fate/complete material III: World material - Records of Heavens Feel - Servant System: Class, p.015
A "Servant Class" is a container prepared for materialising a Heroic Spirit that is summoned into the current era as a Servant.
There are seven Servant Classes: Sabre, Lancer, Archer, Rider, Caster, Assassin and Berserker. Since there cannot be repeats of any one class, the seven Servants participating in a Holy Grail War will be of different classes.
Heroic Spirits determine their classes on the basis of their characteristics, and then summoned as the Servant of the corresponding class. For instance, the only class appropriate for Artoria is Sabre, but Hercules, who was said in legends to be proficient with all weapons, can be summoned into all classes but Caster. The affinity between the Master and the Heroic Spirit will determine which class the Heroic Spirit will be summoned into. However, the Einzberns, as one of the "Three Founding Families" and well-informed of the rules of the Servant system, was able to preemptively interfere with the system and summon Hercules as Berserker.
Among all the classes, Sabre, Lancer and Archer are also called the "Three Knights". They are frequently Heroic Spirits from the Age of Gods when sorceries were common. Due to high magic resistance, modern magi are unable to inflict damage to them.
The Assassin class is special, as the only qualifying Heroic Spirits are the Hassan al-Sabbah's.
Knight of the Sword. The compatible Heroic Spirit naturally needs to possess legends as a knight of sword, as well as the highest levels of attributes in all but MGI. Class Abilities include Magic Resistance and Riding. Also, compatible Heroic Spirits usually excel in delivering powerful burst attacks.
Knight of the Lance. Its high qualifying conditions are second only to Sabre. Attributes are excellent overall, in addition, AGI must be high. Of course, Servants of this class are proficient in hit-and-run tactics that capitalise on range and speed. This class includes many Heroic Spirits who were knights.
Knight of the Bow. A class that excels in possessing powerful Noble Phantasms. The qualifying condition is not attributes, but the possession of powerful projectile weapons or special abilities related to projectile weapons. Highly effective as scouts. They have not only the Magic Resistance ability of the Knight Classes, but also the class ability of Independent Action.
Mounted soldier. Heroic Spirits who rode mounts (not limited to living creatures) qualify for this class. Although attributes tend to be lower compared to the Three Knight Classes, this is compensated by the abilities of the mount described in legend. Besides Magic Resistance, class abilities also include high Riding.
Magus. Qualifying conditions only include mastery of sorceries of the highest calibre. Due to this trait, the qualifying Heroic Spirits tend to have low combat abilities. In addition, since the majority of Servants have Magic Resistance, this class is thought to be the weakest of all.
Assassin. The only qualifying Heroic Spirits are the generations of Hassan al-Sabbah's, and one of them would be summoned. All of them do not have glorious legends as heroes, thus possess low attributes. Class ability is Presence Concealment, and the use of this ability during battle is the lifeline of Assassin.
Mad Warrior. Heroes who have gone berserker during battle qualify for this class. Normally it is considered ideal if a Servant can wield power at the level of the original Heroic Spirit, but "Mad Enhancement" allows for the attribute enhancement of the Servant beyond the ability of the original at the cost of sanity. A class originally used to enhance weak Heroic Spirits.
 Fate/EXTRA material - Saber [Servant], p.192-194
One of the Servants who contracts with the protagonist.
A (self-proclaimed to be) crossdressing young swordswoman clothed in a bright crimson dress. Often called Red Saber to distinguish her from other Sabers.
A headstrong emperor who calls herself an omni-talented genius and actualizes (by force) most of the things she wills.
Though often mistaken for a tyrant because of her arrogance and confident proclamations, as a rule she acknowledges the ways of existences of all manners of people, without rejection.
She judges not by society's standards of good and evil, but by the human beauty.
Having dabbled in plays, song, painting, sculpture, and such various arts, upon creating a new work,
“How’s this? It is quite good, no? T-true, it may be a little on the maniacal side, but is it not good nonetheless?”
A little miss attention seeker who tearfully begs for appraisal like so.
Though she would normally not qualify for the Saber class with her parameters, well, she took care of that part somehow with her Imperial Privilege. She would properly be a commander-type Servant.
As a Servant, she has no particular contentions or wishes.
That is because she is perfect by simply existing.
At least, Saber herself says,
“I am consummate simply by thinking, speaking, and sleeping while being myself. No matter the era, the mere fact of my existence symbolizes the might of Rome.”
Since she’s already perfect, there remains nothing more for her to seek.
She has reached the conclusion that simply being herself is the finest reward in itself.
Since she has absolute beliefs and tenets within herself, she isn’t offended by much.
To Saber, the one unacceptable thing is to “for her to not be able to act as herself.”
The reason why the egocentric Saber is fine with being used as a Servant is because a Servant is contracted as that which “must prove her supremacy.”
“Hmm? I am to prove my supremacy, yes? That I have no complaints about. I shall simply fight a fight not shameful to myself.
Even if I had a frog for a Master, if I can fight together with the frog and emerge the victor without shame, it would become a pride of mine.”
Such is her amazingly optimistic outlook.
And so it’s rare for her to scold the inexperienced protagonist. Though she does grumble about the protagonist’s timidity and fecklessness, in her heart she does not truly look down on the protagonist.
To her, saying that the protagonist is “feeble” is simply an honest appraisal.
Thus, when the protagonist grows as a Master and builds the bond of trust, she becomes more straightforwardly affectionate.
“Confound it all, pay more attention to me!
Since you are contracted to me, you shall put me first of all things!”
Thus the attention-starved puppy emperor came to be.
However, in the first place, there isn’t a Master to be found who would summon her.
Her true name corresponds to great evil in a certain religion, and the end of her life was a miserable one.
Just as much as she is an emperor, she is also an artist with unshakable faith in her own genius, and the only absolute justice to her is “beauty.”
Whether ally, enemy, her citizens, or herself, she will not love anything that does not fit into that category.
That holds true even for a Master. For sure, she will never obey someone she finds unseemly.
There’s no magus who would want to make use of a weapon who judges matters based on something like “beauty.” Contracting with this Heroic Spirit is simply too risky.
“……Well, that’s only natural.
Magi are clever and calculating creatures;
certainly not fools who would entrust their lives to me.”
And so she spent her days in ennui in the Throne of Heroes.
Though she gets lonely, her pride overcame that. She decided not to settle for just anyone, planning on only contracting with a genius of her level.
And so, at the end of another round of preliminaries.
Just when she was about to leave, thinking that there was no one to call her this time either, she heard a faint voice.
When she turned, she saw a nameless someone who, despite being on the verge of death, still fought to stand.
Someone who was not strong.
Someone who had no outstanding talent.
Someone who wasn’t even a proper wizard.
But―――Saber saw a kindling that twinkled like a star in the night, a kindling that refused to fade.
Instantly, she rushed forward.
What she had in her chest was not sympathy for that someone, but anger against the high heavens.
She knew that it was the way of the world for the weak to remain weak and perish, their prayers to no avail.
Precisely because she knew this, she couldn’t stand for it.
What kind of heaven would ignore such powerful will?
Even in the death throes, that nameless one chose not to give up but to fight.
“If it would not answer that purehearted wish, the will of the heavens matters not! How can I not answer the cry of that noble soul―――?!”
Rather than answering summons, Saber had come to the place of selection of her own volition.
While groaning inwardly at the offering up of herself that she had disliked so, she speaks to the nameless soul.
“Answer me―――are you my Praetor?”
She appears in a white bridal dress for CCC, earning the nickname of Bride Saber. Since there’s another Red Saber in Apocrypha now, I feel like we need another nickname for her to cover both Extra and CCC.
Tange Saber……no? Okay, I guess not.
Her rival in CCC is Red Lancer.
One hopes that they can become friendly rivals as idols.
After all, having both experienced similar reactions to their performances, it seems like there’s plenty they can talk about.
Also, her voice when the player acquires her swimwear is a must-listen. Therein lies the max endearing charm of the Tange Saber.

真名：木下藤吉郎 ＞羽柴秀吉 ＞豊臣秀吉
属性：混沌・善 ＞中庸 ＞悪
魔術に対する抵抗力。 一定ランクまでの魔術は無効化し、それ以上のランクのものは効果を削減する。 召喚直後はセイバーとしては低い対魔力だが、召喚日数と共に向上。
騎乗の才能。 大抵の乗り物、動物なら人並み以上に乗りこなせるが、野獣ランクの獣は乗りこなせない。 特筆するような騎乗の逸話を持たないため、これまたセイバーとしては低いランク。
希代の人たらしと呼ばれた秀吉の脅威のカリスマ。 あのサルぶっ殺してやると乗り込んだ武将が次の日にはズッ友になって帰ってきた、 とかいうレベルの日本史上稀にみる問答無用のコミュ力。 おまけ効果で上司や敵に気に入られたり、敵の対応がちょっと甘くなったりする。 7日目にはA+となり、ここまで来ると呪いじみた魅力となり、抗うには対魔力：B以上を必要とする。
絶対のピンチをチャンスに変える奇跡の逃走スキル。逃げ足めっちゃ速い。 仕切り直しと似た効果を持つが、判定成功時には必ず有利な状態で戦闘を再開できる。 ノッブの仇を討つために備中高松から全軍を取って返した逸話がスキルとなったもの。
召喚から7日の間、ステータスが上がり続ける。 日を追うごとにパラメータが上昇し、7日目にはまさに日輪そのものともいえる大英霊へと位階を上げる。 ステータスの上昇と共に各スキル、宝具も強化されていき、4日目以降は神性を獲得、最終的には7日目に神性：Aを獲得する。 ただし8日目以降は同じく7日をかけてステータスが下がり続けていく。 落日とともに姿も老成していき、14日目に消滅する。 日輪とともに駆け上がり天下を取った秀吉の生涯そのものともいえる宝具である。
1日目はランク：Eで幸運判定に失敗した相手の武装宝具を極短時間使用不能にするだけだが、 4日目のランク：Bでは判定に失敗した相手の武装宝具を自身のものにして使用可能に、 7日目に最大ランク：EXとなり自身が宝具判定に成功すると奪った宝具の真名開放(一時的に)が可能となる。 秀吉が発したかの有名な「刀狩令」が宝具となったもの。 この宝具のおかげで秀吉はセイバーでありながら特徴的な自身の武装を持たない、という極めて珍しいタイプのセイバーとして顕現している。 ちなみに本人はそれほど武器の扱いが得意ではないので、使用効果は本来の所有者より劣る。
6日目以降に召喚可能となる城塞宝具。 城塞中心にある黄金の魔力炉から無尽蔵の魔力を放出し、固有結界ともいうべき天下人秀吉の黄金大魔術城塞が顕現する。 黄金炉のバックアップにより自身はほぼ無限ともいえる魔力を行使でき、さらには城塞から豊臣恩顧の英霊を軍勢として出撃させることも可能。 但し、彼らの召喚は黄金炉の魔力によって賄われているため城塞の外では短時間しか戦う事は出来ない。 日本史上最高といわれた防御力を誇る鉄壁の巨大黄金城塞である。 ちなみに徳川はこないよ、五大老だけど仕方ないね。

Master: Illyasviel von Einzbern
Alignment: Chaotic Mad
Noble Phantasm: A
A demigod hero of Greek Mythology, he was born between the King of Gods Zeus and a human girl. He received the violent hatred of Zeus' wife Hera because of his origins and was tormented by the goddess at every turn. However, he entirely overcame the difficulties he had been given, and was enshrined as a god in the end.
Heracles had an extremely violent temperament as an infant, and grew up as a shepherd in order to obtain a gentle heart. Having grown into a fine adult, Heracles was recognized for several feats, and gained two children as well as the right of succession to the throne. However, Hera made Heracles go temporarily insane and he killed his wife and children, ending up in the role of a slave to the king to atone for his sins. Here the jealous king gave him a challenge, the famous Twelve Labors. The Labors were all things that a human could not achieve but Heracles completed them safely, and at the same time he was freed from slavery, he received an immortal body.
However, the adventures of Heracles and Hera's hatred did not end there. Hera's numerous artifices resulted in Heracles' poisoning by his own wife from his second marriage. In his final moments, Heracles cremated himself, surrendering to Zeus's judgment. The gods after consulting recognize Heracles' feats, and he was recruited as a god like his father, becoming a constellation.
An excellent warrior, he possesses the qualifications corresponding to six classes excluding Caster. Other than specializing with the bow, he has mastered every weapon. However, all that is talk about times when he is not Berserker. Heracles as a Berserker has lost his rationality, and exists only to utterly defeat the enemy from the front as directed by Illya. Naturally, there is no such thing as detailed tactics, leaving it to physical ability and brandishing an axe-sword to strike. Astonishingly, with just that, it is a fact that he demonstrates hand-to-hand combat abilities superior to every Servant. Without breaking to even think about defense, he leaves it to his Noble Phantasm "God Hand."
Mad Enhancements: B
The Class Skill that characterizes Berserker, it reinforces ability at the cost of reason. As Heracles' possesses the skill at Rank B, in compensation for losing most of his sanity, the levels of all his abilities rise. Heracles beat his harp instructor to death when he was a child, and had many episodes when he killed people in his rage without even hearing them speak. It seems that for Heracles, Berserker that receives "Mad Enhancement" was an easy class to adapt to. Focusing on controllability when out of combat, the rank of "Mad Enhancement" is suppressed by Illya.
Being close to the strongest Heroic Spirit, even restricted to simple direct melee as consequence of Mad Enhancement, Heracles was undoubtedly the strongest among the Servants. However, because of Mad Enhancement, a variety of sword techniques and skills, and a part of his Noble Phantasms was lost. Having his emotions also sealed off and not able to perform any personally motivated actions, only the reason within his core was not lost, having occasions when he felt something like the will to protect Illya.
Battle Continuation: A
A skill that allows for the continuation of combat after sustaining mortal wounds. It will also reduce mortality rate from injury. Cú Chulainn’s Battle Continuation represents “never give up no matter what”, while Hercules’ represents the ability to survive. The Noble Phantasm that allows for resurrection after death, God Hand, has exceptional compatibility with the “will not die easily” skill Battle Continuation.
The best result is achieved when a resilient body is combined with this skill.
Eye of the Mind (False): B
A danger avoidance ability based on Intuition/Sixth Sense, gained through many ordeals and adventures. Even though Hercules’ sanity was lost due to Mad Enhancement, this skill remained effective as it is nearly an instinct. When crossing swords with a seasoned swordsman like Artoria, he would not fall for half-hearted feints. It is such a troublesome ability for Hercules’ opponents.
Although monstrous in size, Hercules has the highest rank in Agility. As a result, it is very difficult to corner him.
With his brave and daring spirit, Herakles is able to neutralise mental interference such as suppression, confusion and charm. However, under the influence of Mad Enhancement, this skill is unable to take effect. While operating correctly, Bravery also increases the damage inflicted upon the opponent during melee combat. This skill allowed Herakles to defeat several monsters empty-handed.
Even the brave warrior’s heart was painted over by the insanity of Mad Enhancement.
Being a mixed-race child of the King of Gods Zeus and a human, and becoming a god after death, Herakles naturally possessed the highest level of the Divinity skill. However, this matter became a disaster, ending with his complete entrapment in Gilgamesh's Noble Phantasm "Chains of Heaven" that grows in strength proportionate to the enemy's Divinity.
God Hand: Twelve Labors
A blessing of Gods, as well as a curse. It is a Noble Phantasm given to Heracles, representing immortality. This Noble Phantasm does not have an overt external manifestation such as a weapon or armour, but if you hazard to put a shape to it, the body itself can be called the Noble Phantasm. God Hand turns one’s body into a tough suit of armour and nullifies all attacks Rank B or lower, regardless the attack being physical or magical. It also has the effect of automatic resurrection after death. Because the resurrection effect has 11 uses, Heracles cannot perish unless killed 12 times. In addition, due to Illya’s immense magical energy, given enough time, the lives lost can also be regenerated.
Resurrection as well as attack-nullification. Besides these two effects, God Hand also possesses a third effect: rendering an attack that it has experienced before useless. Regardless how powerful is the Noble Phantasm that defeated Heracles, it would be completely nullified after he resurrects.
Nine Lives: The Shooting Hundred Heads
Maximum Targets: -
Among Hercules’Noble Phantasms, he trusted this one the most. It was the Noble Phantasm which Hercules used to slay the immortal nine-headed serpent Hydra once upon a time, taking the form of bow and arrow. After killing the Hydra, Hercules could even utilise techniques that emulate the ability of this Noble Phantasm when wielding other weapons. In essence, it is “a high speed attack consisting of nine consecutive strikes, as swift as if the attacks are overlapping”. Even when delivered via sword, spear, or axe, this technique still boasts power on the level of Noble Phantasms. Also, just like Cú Chulainn’s demonic spear Gae Bolg has a technique called “Gae Bolg – Piercing Death Thorn”, Hercules’ technique shares the “Nine Lives – Shooting of Hundred Heads” name with the Noble Phantasm.
Shirou projected this secret sword technique while projecting Hercules’ Axe Sword, thus annihilating the Blackened Hercules. While summoned as a Berserker, Hercules could not use Nine Lives.
 Fate/complete material IV: Extra material - Fate/Apocrypha - Joan of Arc, p.343
Joan of Arc, the Standard-Bearer who Correctly Guides the Holy Grail War
Joan of Arc is a Servant of the Ruler class, with the additional classification of the Saber class, designed by Kinoko Nasu. She is a Catholic saint born in Domrémy, France, and the heroine of France who liberated Orléans in the Hundred Years' War. She is a special Heroic Spirit summoned by the Holy Grail itself to act as the administrator of the "game" unlike other Servants. She is taciturn and cool when acting as a Servant, but her natural self is a plain and quiet sixteen-year-old girl. She puts order first, and will wield a sword for the sake of the rules, but fundamentally believes "all people and Heroic Spirits participating in the Holy Grail War are important".
- Class: Ruler (Saber)
- Source: Historical fact
- Region: France, Domrémy
- Alignment: Lawful Good
- Sex: Female
- Height: 159cm
- Weight: 44kg
- Armament: Flag
- STR: B
- CON: B
- AGI: A
- MGI: A
- LCK: C
- Noble Phantasm: A++
- Magic Resistance: EX
In addition to the Magic Resistance of the Saber Class, she demonstrates a high anti-magic from her unwavering piety. However, since it is just averting (evading) the Magecraft, only Joan will be saved against a wide-range magic attack. It cannot cope with the sacraments of the Church.
A Skill equivalent to "Instinct". Instinct is a sixth sense regarding battles, but "Revelation" accommodates all matters related to the achievement of a goal (for instance, choosing the most suitable path while traveling). Because there is no basis (so she thinks), it cannot be explained well to others.
The natural talent to command an army. Joan's figure participating in the assaults hoisting a flag raised the morale of the soldiers to the limit and united the troops. Thanks to her charisma, it is possible to make others believe in the contents of the "revelations" without basis.
Indicates being acknowledged as a saint. When summoned as a Servant, the ability of saint is selected one among "raising the effectiveness of sacraments", "automatic HP recovery", "1 Rank-Up to Charisma" and "production of a holy shroud is possible".
- La Pucelle: The Crimson Holy Virgin
A holy sword that manifest flames which uses the line of a death poem "O Lord, I entrust this body to you---" as activation incantation. A conceptual crystallization weapon that interpreted Joan's burning at the stake in an attack-like fashion. A subspecies of Reality Marble, an imagined landscape crystallized as a sword. This sword is Heroic Spirit Joan of Arc herself and after the battle in which this Noble Phantasm was manifested, Joan will be extinguished.

 Fate/Apocrypha material - Encyclopedia: Berserker of “Red” [Servant], p.151-152 [T]
Berserker of “Red” [Servant]
One of the Servants of the Red camp. A Servant truly worthy of the title of mad warrior, who completely ignored the plans of the other Servants and Masters and disappeared like a star after merely rampaging around. His true name is Spartacus, the strongest gladiator who raised a large-scale rebellion of slaves in Ancient Rome.
Spartacus was the leader of a revolt and led the other slaves as a skilled leader, but he always fought at the head of the front lines, and even when the revolt was subjugated by the army, he fought until his death. Perhaps due to that, Spartacus’ corpse is said to have been torn to pieces and never found anywhere on the battlefield afterwards.
Having been summoned as a Berserker, Spartacus is always thinking of only “rebellion”. Because of that, it is widely said that he is a Servant who wouldn’t hesitate to kill his own Master and whose “defeat is certain from the moment he is summoned” among the regular subspecies Holy Grail Wars—However, in truth, Spartacus wouldn’t actively revolt against his Master. His Mad Enhancement is EX rank and it is virtually impossible to come to a mutual understanding with him, but he is capable of judging whether his Master is an “oppressor” or not.
…The problem is that pretty much all the Masters who participate in the subspecies Holy Grail Wars are magi in the first place, and they are categorized as oppressors in the eyes of Spartacus.
If his Master was someone who “accidently got involved in the war”, it would be fully possible for Spartacus to fight at their side right until their defeat. Though I will not give names, he is particularly compatible with a certain red-haired boy. His battle is always against those above him and against himself, after all. Of course, it’s another matter entirely whether or not they would be able to achieve victory in the Holy Grail War.
Though the chances of it are low, should Spartacus be summoned as a Saber, even more caution (in terms of rebellion) would be needed against him, demonstrating how troublesome a Servant he is. But he might still have a chance of winning if he was chosen by a child who doesn’t know anything.
