Any type of attack against him is nullified, physical damage, the "normal attacks" of Servants, and even great Noble Phantasms like the A+ rank Balmung. It cannot be pierced by power alone, but rather only those who possess the blood of a god within their veins are permitted to harm him. 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. Without there being someone able to harm and defeat him, it can be said that the Black Faction cannot win the Great Holy Grail War. 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. He has second weakness in that his invincibility does not apply to acts that display friendship. The act of being bitten by a vampire is a act meant to make him into a comrade rather than kill him, so his body will respond making part of himself weak in response to that request.
