Enuma Elish

Star of Creation that Split Heaven and Earth.
The cutting of space with the Sword of Rupture, Ea.
Air pressure faults, compressed and smashed against each other, become a pseudo-fault in time and space that pulverizes all who oppose it.
With output matching or even exceeding Excalibur, it is without a doubt the sword that “cut the world.”
Strictly speaking, the Noble Phantasm is actually Ea, while Enuma Elish is the name of Ea’s maximum output state.
…By the way, the sword’s drill shape is modeled after the bedrock excavators used when making underwater tunnels.
Though normally you’d think of a drill as something that tapers down to a point like a spear, the drills used to bore out enormous holes actually look more like numerous overlapping gears.
The way the blades rotate individually and shave away at the bedrock… just imagining it is so cool!

Fate/side material: Fate Encyclopedia

Anti-world noble phantasm that destroys everything. This noble phantasm is the maximum power state of Ea, Sword of Rupture. Dislocations of compressed intertwined layers of wind pressure create a pseudo time-space dislocation to cut through space. This unbelievable power cuts the World itself, completely pulverizing all enemies. It can only be offset by a simultaneous blow delivering an equivalent level of damage. Using this attack in combination with launching other noble phantasms from the treasury further increases its lethality.

Star of Creation that Split Heaven and Earth.
A freaking strong Noble Phantasm. An official cheat that will one-hit KO almost every Heroic Spirit if shot from the beginning.
If it’s Gilgamesh himself, he won’t draw it recklessly due to personal restraints, but Angelica-san, who didn’t know a damn about the dignity of a hero, fired it quickly. Shirou attempted to offset it by mobilizing all the swords within the Bounded Field, and failed. He succeeded in attenuating it considerably, but was defeated with the breaking of the Bounded Field. At this time, the wound inflicted in the space of the Great Cavern by Ea did that to the location and became like this, and Illya’s world and Miyu’s world were shifting or something like that. As expected from an Anti-World Noble Phantasm!
A simple method of calculating the output is STR×20, in short, the power will increase the higher the Strength. It’s a real relief that Angelica isn’t beefed. By the way, when Child Gil shot it against Illya, it was considerably weaker than the original.
