Differing from that of Karna's spear meant to bring about destruction with immense weight, it is a simple spear with sturdy workmanship that is well designed for close combat. Pierce the chests of heroes, he holds it lightly in one hand as a means of using for its original purpose as a throwing weapon. Having been able to pierce through all other heroes, he feels it is superior to any other weapon in the aspect of its thrust, allowing it to pierce hearts and penetrate skulls with every strike he makes.
When summoned as a Lancer, this spear would also gain abilities similar to Gáe Buidhe, in which wounds inflicted by this spear cannot be healed as long as it exists. However, since Achilles would not have access to his chariot, he would need to rely on his feet for mobility.
During his life, he developed an ability with the spear that not even Chiron knew of, using magecraft to create a Duel Field (決闘場, Kettō-ba?), a fair battleground between two opponents, where no gods, outside help or elements of luck can intervene. It creates an arena cut off from all of the surrounding environment and time, which isn’t released until one of the combatants is defeated. In terms of magical theory, it is virtually the same as Aestus Domus Aurea. It is a separate dimension outside of time that is comparable to a Reality Marble, so when the duel within concludes, it will have lasted only a second from an outside perspective. Due to Hector not wishing to fight Achilles with the advantage of his immortality, he developed the ability so that they could evenly fight. The dueling rules must be agreed upon by both parties so it is useless against someone refusing to duel. While the fight against Chiron in Fate/Apocrypha involves only fists, weapon usage can be permitted. Achilles must descend his chariot to make this Noble Phantasm function usable. And due to the nature of this Noble Phantasm and the curse by the Amazonian Queen, it can neither be used on someone weaker than himself or on a female. The three people that Achilles never wants to have a rematch with regardless whether it is before or after his death are Hector, Penthesilea and Chiron.
In the original light novel of Fate/Apocrypha, the design for the spear was incomplete and it wasn't fully seen until the anime adaptation. The spear bears a teal tip and rings upon its handle in A-1 Pictures' adaptation of the Fate/Apocrypha anime.

Spear-tip of the Star Traversing the Skies [Noble Phantasm]
Diatrekhōn Astēr Lonkhē. The Noble Phantasm of Rider of Red, Achilles. To describe it in a single phrase, it is a spear for fighting one-on-one. It creates an arena cut off from all of the surrounding environment and time, which isn’t released until one of the combatants is defeated. In terms of magical theory, it is virtually the same as “Aestus Domus Aurea: Golden Theater of the Flamboyant” that Red Saber-san from “Fate/EXTRA” creates.
It can be called the ultimate contest of pure strength and skill that negates even “flukes” caused by things like divine blessings or luck. Achilles used this when he fought Hector. Furthermore, while he fought barehanded in his fight against Chiron, nothing prevents either combatant from using weapons in this arena.
Also, since Achilles killed the Amazoness Queen Penthesilea with this spear, he cannot use it against women. In the first place, this spear can only be used against “those who Achilles wants to fight one-on-one against”. In other words, if Achilles doesn’t “wish to fight them” and the opponent doesn’t have enough courage and skill to respond to his challenge either, Achilles won’t use this spear. Furthermore, even if Achilles himself wants to fight them, he won’t try to forcefully bring his opponents into the one-on-one arena if they don’t want to. It is a Noble Phantasm with a narrow range of enemies it can be used against.
Also, if Achilles should be summoned as a Lancer, it will gain an additional ability separate from the arena creation ability; it is a power that resembles “Gáe Buidhe: Yellow Rose of Mortality”, which “makes healing impossible when one is wounded by this spear”. He doesn’t have his chariot in the Lancer class, but he can wield this spear with divine speed while dashing around the battlefield with equal swiftness, so he is an unmanageable threat in either class.
 Fate/Apocrypha material - Encyclopedia: Hektor [Person's name], p.183 [T]
Hector [Person's name]
The greatest rival of Rider of Red, Achilles, during his lifetime. He was the strongest hero on the side of Troy during the Trojan War. Also, his younger brother Paris is the perpetrator who caused the Trojan War to happen.
He is the exact opposite of Achilles as a hero, a bearded middle-age man who likes to play the fool. He refers to himself as “mister” (old man) in his speech, and always fights on the battlefield with an easygoing attitude.
He’s ruthless, but not cruel; skilled, yet not gifted. He faced other famous heroes besides Achilles, without retreating a single step… or not; rather, he would often retreat two or three steps and then strike the enemy when their guard’s down, before running away again, and just when they think he’s far away, he throws mud at them; a-anyway, he prided himself at being the strongest when it comes to siege battles.
He uses dual long-sword/throwing spear called Durindana, and by throwing it he managed to pierce through six of the barriers of “Rho Aias: Seven Rings that Cover the Fiery Heavens”, which boasts the greatest rank of toughness against projectiles.
In order to settle things once and for all with him, Achilles challenged him to a sink-or-swim duel, where he temporarily gave up his immortality. Unable to resist the temptation of getting the chance to take Achilles’ life, Hector accepted the one-on-one duel and was defeated by a paper-thin difference in skill.
To Achilles, Hector is one of the top three people he never wants to fight again, whether it is before or after his death. The remaining two are Penthesilea and Chiron.
