Sha Naqba Imuru: The Omniscient Omnipotent Star (全知なるや全能の星, Zenchinaru ya Zen'nō no Hoshi?) is the mentality of Gilgamesh sublimated into a Noble Phantasm, said to have "spread across all corners of the world as if the brilliance of the stars, seeing through all creation." It is a "continuously active-type Noble Phantasm" that does not require its name to be invoked, but it is assumed that Gilgamesh keeps it intentionally restrained. Possessing tremendous efficiency, it can discern heavily concealed truths with a single glance, from that of the opponent's True Name and Noble Phantasms to possibly even seeing through a piece of the truth of the demise of human history in the Grand Orders of Fate/Grand Order. Upon releasing its True Name, it will work as a form of "instruction" for him to guide others with the most optimal tactics, simultaneously increasing the attack power and defense power of his whole team near his position.
Gilgamesh is a clairvoyance user with a "sense of 'sight' several levels above the ordinary." When facing him in a game like chess, he claims that even someone making advanced predictions and reading the flow of the game will have already lost at that moment. He does not read the future of the chess board, but instead gazes down upon and oversees it, allowing the correct move to always be visible to him. Even in something like a card game, the very minimum requirement to play against him on equal terms would be to draw the precise hand required. He can also see the possibilities of various parallel worlds should he so choose, such as being able to see his participation in the Fourth Fuyuki Holy Grail War and even glimpse the world of Fate/hollow ataraxia, albeit accidentally. But, as a Heroic Spirit, the Throne of Heroes normally adjusts his memories and knowledge to the world in which he is summoned in to keep him from being confused by multiple sets of memories. Even with this ability, his personality would cause him to reject certain world lines as nonsense, such as using clairvoyance to see something like a possibility of a world where he is swallowed by the mud of the grail. Grail mud is also able to block his view.
The Noble Phantasm was first introduced in the Toraburu Hanafuda Travel Journal mini-game in Fate/hollow ataraxia as the Noble Phantasm Skill of Child-Gil, allowing him to view some of the cards in the opponent's hand and deck. It was not classified as a plot-related Noble Phantasm until Child-Gil was released in Fate/Grand Order over ten years later.

Gate of Babylon: King's Treasure
Type: Anti-Unit Noble Phantasm
The King of Heroes of Uruk. Mankind's oldest hero.
His nature is cruel and heartless. Never hearing people's opinions, a tyrant who holds only his own standards as absolute-- such disposition is not applicable to him in this form.
Fundamentally, a polite and modest boy.
Level 1 Bond
Source: Historical fact, Epic of Gilgamesh

His type of woman goes along the lines of a "flower that blooms in the wild".
Level 2 Bond
It is not sure if this is something in which "he", who manifested in his usual state, became younger by eating the miracle drug of rejuvenation, or if he had manifested in the form of his younger days from the beginning.
It is believed that what is acting as the model for his mentality is the heart from when he was called a wise ruler in the past.
Level 3 Bond
- Pretty Boy of Rosy Cheeks: C
A Skill that denotes the disposition of a pretty boy that attracts people.
It works as a fascination magecraft-like effect regardless of gender, but evasion is possible by means of Magic Resistance Skill. Even without Magic Resistance, one can abate it so long there is a will to resist.
Level 4 Bond
"The Omniscient and Omnipotent Star"
Rank: EX Type: Anti-Unit Noble Phantasm
Sha Naqba Imuru.
The mentality of the King of Heroes - which spread across all corners of the world as if the brilliance of the stars, seeing through all creation - sublimated into a Noble Phantasm.
A continuously invoked-type Noble Phantasm. In regards to this work, the only Noble Phantasm he performs the release of True Name is "The Treasury of the King".
Level 5 Bond
The efficacy of the Noble Phantasm, Sha Naqba Imuru, is tremendous; not to mention the opponent's True Name and Noble Phantasm, it can even see through a heavily concealed truth with a single glance.
Although it is in a condition of being continuously invoked, one can also assume that it is being intentionally restrained.
Thus, maybe he has even attained a piece of the truth regarding the demise of human history.
Yet, he won't say a thing.
He only watches over the Master's fight and smiles.
He may spare no efforts in his assistance, but still--

Question: So there is still quite a bit of background information that has yet to be revealed.
Narita: That’s right. One of the most core pieces of information had been about the conditions for becoming a Heroic Spirit. This was revealed in a bonus novel that came with the UBW 1st season BD box. About how Merlin is still alive in the present so he can’t become a Heroic Spirit. As Gilgamesh is also a fellow clairvoyance user, I asked about the state of Gilgamesh’s memories when he’s summoned. The answer I got was that Gilgamesh can see the possibilities of various parallel worlds if he so chooses, but the Throne adjusts the memories and knowledge of the Heroic Spirit according to the world they are summoned in, so he won’t be confused by having multiple sets of memories. I was told that even if he did use clairvoyance to see the possibility of a world where he was swallowed by the mud of the grail, Gilgamesh would reject that world line as being nonsense. I heard a bit of the workings of the Greater Grail, what it was based on, and other bits of important background information for Fate, but I believe Nasu will one day write the story of how the Greater Grail was disassembled!
