Keeper of Gil's Vault wrote:What Raitei said. Objects of ancient origins possess powers matching that of sorcery without being "magical". Basically the accumulation of age can cause animate and inanimate objects to gain almost magical properties. Therefore, a relic such as an ancient spear may hurt a servant without being a NP. The extend of the damage, however, will depend on how potent its mystery is.
You are not entirely wrong in saying modern weapons cannot hurt servants, but also not entirely right. Kiritsugu's br0ken weapon is not quite a pistol. To be more specific, I believe it is a conceptual weapon.
I understand the part about the weapons he traces being magical themselves, but I merely meant in general that weapons Shirou makes can have more effect on a Servant than normal weapons simply because they are made of pure prana. Thats merely speculation on my part, but considering that spells have effect on Servants because they are an attack using prana rather than physical force I think my line of thinking is not far off. And yes, its true that modern weapons have no effect on Servants, but Kiritsugu is a mage and as such has the knowledge to bend this rule. So yes, I am entirely right in saying that modern weapons cannot hurt Servants. I don't think Kiritsugu's weapon falls into the same category as every other "modern weapon."
