Enkidu: Chains of Heaven (天の鎖, Ten no Kusari, spelled "Erukidu" in some versions?) is the Noble Phantasm most trusted by Gilgamesh, even more so than Ea, and the "greatest secret" stored in the Gate of Babylon. It is a chain named after his closest friend made to bind the gods so they cannot escape, making it one of the few anti-divine weapons that holds the concept of "reigning over the gods." The strength and durability of the chain grows stronger with the target having higher divinity, but is no more than a tough chain to a target without divinity. Divine targets are completely held in place, allowing him to bind the "Bull of Heaven" that brought seven years of famine in Uruk. It does have some sort of limit, as even he is able to tell that the chain is not enough to completely bind the demi-god Heracles strengthened by Mad Enhancement.
Gilgamesh is capable of taking out the entire length of chain from the Gate of Babylon to use in conjunction with Ea when he is serious about fighting, or he can simply summon part of it from the Gate. The chain can be summoned from anywhere the Gate of Babylon can reach, elongate and contract without any shown limit, and multiple individual sections can be summoned at one time. The blade on the front of the chain is capable of acting as a striking weapon when launched at a high speed, and he can summon a single length to wrap around an opponent so he can drag them towards him by pulling it. Even against non-divine targets like regular humans, it is still a Noble Phantasm nearly impossible pry off once it has gotten a hold of them.
Once activating it as a Noble Phantasm, numerous segments instantly appear to wrap around the opponent in order to bind them for his projectiles. It is shown both descending from the sky and appearing directly from inside the Gate of Babylon. He generally binds the opponent's weapon, limbs, shoulders, neck, and abdomen, rendering them completely immobile. The chains continuously twist and tighten with enough force to attempt to tear off Berserker's head and bend his arms past their limits in a normally impossible direction. It appears to even bind the space around itself, and it is capable of rendering transportation ordered by a Command Spell, which is capable of magecraft close to that of True Magic, completely useless and nullified. It is possible for a divine target to break the chain, such as when Berserker pulls off the impossible by using the last ounces of his strength. That doesn't actually destroy it as Gilgamesh later uses it again to grab the arm of Shirou Emiya.
