Ark: The Ark of the Covenant (契約の箱, Keiyaku no Hako?) is a wooden box that contains the original engravings of the Ten Commandments issued to Moses by God. As a Noble Phantasm, its effect is narrow but absolute; besides the Servant that carries them, all those who would deem to touch the box without authorization are drained of their magical energy unto death. Upon seizure of Jerusalem and the removal of the Philistines, King David of Israel appointed the city as his capital, and situated within it the Ark of the Covenant. It is summoned into the world independently from Archer, and it cannot be changed into spiritual form. It is powerful enough to overcome even Heracles's stock of lives from God Hand, killing him instantly.
In Fate/Grand Order, it is a powerful artifact sought by Jason to grant him ultimate power in the Okeanos Singularity by sacrificing a god to it, but it is revealed that it is a lie by Medea Lily under the command of another magus. Sacrificing a god, an avatar of the world, to the Ark is considered the same as sacrificing the world, so the Ark will bring calamity to the world in the same way it would to a person who touched it. While it would only normally destroy the surrounding area, the fragility of the Singularity would bring about more destruction.
In ~turas realta~, though he was incapable of touching it, David was able to pull the Ark in his direction by reciting the chant: "That 'Holy Box' should never be touched. He who is neither priest, nor bears the name of Levi, be ready to sacrifice your life. For that is the Ten Commandments, protected by Cherubim. The testimony of our faith, bestowed upon us from the peak of Mount Sinai. Come, Ark of the Covenant."

King of Israel
David is based on the king of ancient Israel who appears in the Old Testament. Placing his duty as an agent of God first and foremost, he possesses the strength of will to maintain an extreme calm in the face of utter desperation, clear-mindedly evaluating his situation in a realistic manner. To his view, "All humans upon this earth have a place within God's plan," and should be regarded with appropriate respect. Typical of many heroes, however, he has a weakness for women with nice bodies, occasionally muttering, "I wish to take a wife for myself ..." Though he is considered an unparalleled genius in his talent with a harp, he possesses little skill in dancing. However, he favors both as his pastimes.

As a shepherd, he was told by the prophet Samuel that he had been given a special role from God. He is famous for episodes such as performing with a harp in front of Saul, king of Israel, to exorcise him from an evil spirit, and defeating the Philistine giant Goliath. Saul soon became jealous of David's glory in battle, and he became the target of assassination attempts. However, after Saul dies in battle with the Philistines, David ascends the throne and conquers Jerusalem. David's only disgrace is his disregarding the law to pursue the married woman Bathsheba. He murders his vassal to obtain her, and he endures God's punishment for it in his last years.

- Divine Protection
The form and flesh of a man prophecized to be king, bearing the quick-wittedness and brute strength to defeat beasts unaided. Though he has been resurrected by the power of the Grail, Servant does not regard himself as a vessel to the soul of his original -- merely as an instrument of God. He does not terribly mind this existence, content merely to feel the grace of his Lord.
- Harp Performance
In life, the Servant is said to have exorcized evil spirits on the behalf of King Saul of Israel with use of his harp alone. His skill with the instrument is such that he is capable of purging mental interference and restoring psychological stability to those who listen to his music. However, the accuracy of projectiles and polearms suffer a large Rank Down within hearing range. The Servant's act of exorcism may have a modern analogue in musical therapy.
Though the Servant was originally a mere shepherd in life, as an ancestor of Christ, he qualified weakly as a being of divine nature -- perhaps equivalent in rank to Joseph of Nazareth. He possesses some defense against the action of conceptual relics and Noble Phantasms based in the divinity of Christ (though not those based in the divinity of God) -- for example, "holy shrouds," "the stakes of the Crucifixion," and "the Lancea Longini"; possibly even "the Holy Grail."
A prodigy of military tactics and command in life, the Servant called to arms a force of 320 thousand men to seize the city of Jerusalem. For the long path of bloodshed that he wrought as a military leader, he later deemed to seek the forgiveness of God by building a place of worship in his capital. (Due to certain circumstances, it was not built until the reign of his son, Solomon.)
- Hamesh Avanim: The Five Stones
The slingshot that defeated the giant Goliath. A Noble Phantasm that consists of five decorated stones bound by the line of a sling, normally carried behind the Servant's waist. Hamesh Avanim expresses David's generosity: As projectiles, the first four stones are used as warning shots as the Servant attempts to persuade his opponent to lay down arms. If said opponent fails to comply, the fifth stone may be launched -- a rapid, nonlethal attack that is extremely difficult to evade. Normal Heroic Spirits are rendered unconscious on impact, and their belongings are "redesignated" to the possession of the user of the Hamesh Avanim; that is, even if they take hold of their former Noble Phantasms, usage is disallowed by divine authority. The sling itself is the true Hamesh Avanim, and the five projectiles are merely normal stones that have undergone transfiguration; they may be unendingly replenished.
- Sacrifice: Flames Upon the Altar
The "flame that carries the hottest heat, shinning brightly, which flared up by God's commands" which appears in the Book of Numbers of the Old Testament. A phantasmal incense burner in deactivation. Ketoret is burned within, and when the violet fumes that issue have enveloped the target, thunderclouds and mist gather overhead -- giving the impression of Mount Sinai; from them, a fire descends from the heavens, incinerating without a trace all those who would oppose the will of God. The flames are shaped like an altar.
- Ark: The Chest of the Covenant
A wooden box that contains the original engravings of the Ten Commandments issued to Moses by God. As a Noble Phantasm, its effect is narrow but absolute; besides the Servant that carries them, all those who would deem to touch the box without authorization are drained of their magical energy unto death. Upon seizure of Jerusalem and the removal of the Philistines, King David of Israel appointed the city as his capital, and situated within it the Ark of the Covenant.
