Saber as well lowered her sword, measuring the distance between her and Lancer with greater caution.

Exposing one's Noble Phantasm can have two different kinds of effects.

One type is the demonstration of the large power of one's deadliest move as they announce its true name. Take Saber's ultimate secret move. She has "Excalibur • the Sword of Promised Victory" currently protected behind a bounded field of invisibility, but if she throws away the camouflage and shouts its true name, her sacred sword would shoot a stream of light that can mow down a thousand soldiers. As it truly is an anti-fortress Noble Phantasm that can turn the ground into scorched earth, it cannot be used just like that but as a last step.

Along with that, there can also be how the weapon already carries the nature of a Noble Phantasm. In Saber's case, her "Invisible Air • Barrier of the Wind King" is an example. That alone doesn't have the capacity to annihilate the enemy; it is more a Noble Phantasm suitable in battle as a "sharp tool". It isn't particularly used for strength, but to put it differently it is easier to use, and a trump card that can bring victory if used well.

And so, Lancer's red spear is—

Probably, the latter. So said Saber's intuition. Lancer will keep exchanging continuous blows with Saber. She doesn't suspect the next strike to be decisive for the fight.
