Keep in minds Noble Phantasms are "crystallized mysteries", powerful armaments made using the imagination of humans as their core, and weapons or abilities owned by Heroic Spirits. They are the embodiment of the ultimate mysteries of a hero that symbolizes his existence through historical facts and anecdotes. They can be physical weapons, such as swords, lances, and bows, or support items, such as rings and crowns. They can also be abstract concepts, like unique abilities, unique means of attack, curses, and changes to the environment and its physical properties. When summoned as Servants in the Holy Grail War, they are the trump cards of the heroes that allow them to overcome others in battle. The problem here is what do these guys have that can fit these profiles and categories.
