Andres Amarantos: Amaranth of the Brave (勇者の不凋花, lit. Brave Amaranth?) is Achilles' gift of immortality from his mother, the goddess Thetis, not including his weak-point, his heel. Although his mother had wanted to make him fully immortal by warming him within holy flames, her husband, Peleus, opposed it because it would "destroy him as a human", so only his heel remained human. It kept him from receiving any wounds in life until his weak-point was exposed during his fight with Hector, and later utilized by Paris to kill him under the guidance of Apollo. Any type of attack against him is nullified, even including great Noble Phantasms like the A+ rank Balmung, and it cannot be pierced by power alone. It can only be negated by those with Divinity of a certain rank, at most C-rank, or higher, allowing those of that rank to harm him with any attack. Saber of Black, with no Divinity, is unable to give him a single wound in drawn-out combat, while Archer of Black, with C-rank Divinity, is able to draw blood with a simple arrow. Invasive acts that are considered to be "friendly actions" like a being bitten by a vampire are not negated.
