According to Saber's judgment, even using it seven times in succession would not require replenishing mana.
An ordinary Servant would have to rest after several battles, but Lancer could fight six consecutive one-on-one battles, all thanks to this Anti-Person Noble Phantasm's extremely low mana consumption.
If Cú Chulainn threw it, the Noble Phantasm became an Anti-Army Treasure Tool that could only be resisted through a frontal defense.
A specialized Noble Phantasm unleashed by releasing Gae Bolg's curse to its utmost power and throwing it with all one's strength.
Gae Bolg had originally been a throwing spear. This was its proper use, Cú Chulainn's Strongest Attack and the move that had made his name.
Because Gae Bolg's curse had reached its absolute limit, unlike the "Piercing Death Thorn Spear," the only ways to defend against this spear were to erect a barrier with greater mana than the spear itself or prevent Cú Chulainn from using it. Otherwise, it could not be avoided.
After the Death Thorn Spear struck, regardless of whether it hit the heart, it would unleash a thousand barbs, and the wound could not heal .
That was why the dog spear in FGO reduced defense. According to Fate settings, the dog spear was carved by Old Woman from the skull of an incredibly badass sea monster. Even if it was not a divine artifact, as Old Woman's favored weapon, it was still at the level of a divine artifact.
Old Woman had even researched an entire set of spear techniques and throwing techniques.
Cú Chulainn hurled his demonic spear at Chang Wei.
The crimson demonic spear turned into a streak of red light, bypassed several Golden Men blocking its path, and finally reached Chang Wei, only to be stopped by the last Golden Man standing close to him.
