King of Conquerers vs King of Heroes?

Allows the planar manifestation as Servants of Iskander's personal guard, who vowed allegiance to him even after death and became Heroic Spirits together with their lord. The summoned warriors are all Master-less Servants, however each have the rank E- equivalent of the "Independent Action" skill, allowing materialization possible for a maximum of 30 turns.

The name "Ionioi Hetairoi" means "Ionian Companions", where "Companions" refers to elite shock cavalry of the Macedonian army. Alexander was known to personally lead his royal guard Companion squadron to battle.

Strictly speaking, the Noble Phantasm is the Gordius Wheel (ゴルディアス・ホイール, Gordius Wheel?), Wheel of Heaven's Authority (神威の車輪, Shin'i no Sharin?); just like what Enuma Elish is to Ea, Via Expugnatio is the trampling attack performed with the Gordius Wheel.

The damage is decided by two rolls, for the hooves of the divine bulls and the wheels of the chariot. Along with all physical damage, there also is the effects of lightnings, the manifestation of Zeus. Should the target fail its STR check, additional damage will be dealt.

The key-like sword (which is the Noble Phantasm itself, not the vault) to enter the golden capital of Gilgamesh. It opens a portal in space that allows him to take out the items inside as he pleases. Goes without saying that the more wealth he has, the stronger a Noble Phantasm this is. Weapons in it can be thrown out like projectiles or taken out normally. Strictly speaking, the weapons inside it aren't Noble Phantasms but the prototypes of them, or one way of putting it, nameless/fameless Noble Phantasms. The most dangerous thing for other Servants though is as Gilgamesh has most of the weapons that became Noble Phantasms in his vault, most often he'll have a weapon that had been their weakness when they have been alive.
Rank: E-A++ (of course Ea is also in the Gate so technically he does have one EX weapon in it)
Type: Anti-personnel

By compressing and accelerating wind pressure, it becomes a fake space-time dislocation that pulverizes any opposition. With an output power surpassing Saber's Excalibur, it is the "sword that cut the world apart". Strictly speaking, the Noble Phantasm is Ea, and Enuma Elish is the name of the attack at its highest power.

Its attack power is so strong that an elimination rank AC or a counterattack with an equivalent damage level is needed to defend against this Noble Phantasm. Damage is STRx20 but MGI can be added to STR at random. The maximum damage is 4000, but it can increase even further with the support of the Noble Phantasms in his treasury. The wealthier, the stronger.

The Noble Phantasm that Gilgamesh trusted the most, even more so than Ea. One of the few anti-god weapons that has the power to "reign over the gods". The higher the divinity, the stronger it is. Against those with no divinity, it's about as much trouble as a tough chain.
