Helm of Clouded Vision
Machination of the Wicked Sorceress
Type: Anti-Unit (Self)
Rank: C-
Range: 0
Max Target: 1
A magic helmet given to Saber by Morgan Le Fay before she assigned him a mission to slay one of her enemies. Unknown to him, the enemy was none other than Artoria. The helmet was enchanted to conceal Saber's identity, so that he may return to Camelot without tarnishing his reputation. That way, he would be able to destroy her half-sister's great kingdom from the inside.
It may be tought as a "prototype" of Secret of Pedigree. Like it, it hides to other data about his personal skills, his true name and his Noble Phantasm. However, unlike Modred's perfected version, this effect will disappear the second he removes his helmet. Fortunately, he is greatly attached to his loved one's gift and will not remove it unless forced by a Command Code. While some may be able to get a feeling of knowing his identity from clues, they will be unable to reach a definitive conclusion.
It has a far more devastating side-effect. When using it, it also cloud Saber's sight and thoughts. . While he can hear what other people say, react to their actions and superficially interact with them, he sees them only as unidentifiable shades and will not recall their identities. He can recognise his master to an extent and will detect the aura of servants, but he won't remember any further details. It was this effect that prevented him for recognising his king when he fought against her. Furthermore, it even hide from him data about his life, such as his fateful fight against his lord or the True Names or effects of his other Noble Phantasm. The only exception is his beloved Morgana, who he will recognise instantly.
Excalibur Morgan
Sword of Stolen Victory
Type: Anti-Unit
Rank: A++
Range: 1-2
Max Target: 1
Prior to Saber's duel with Artoria, Morgan managed trough trickery to steal Excalibur from her and replace it with a normal sword. She then gave the legendary sword to him so that he may kill the king with her own weapon.
Due to Saber's distorted mind and Morgan's influence over him, Excalibur was changed into its corrupted form. However, Saber doesn't know the true name of this Noble Phantasm and thus may not activate the abilities it would have if used by a corrupted Artoria. Even if he were to learn its true name, he wouldn't be able to use it. To replace it, Morgan has enchanted it to give it nearly equal, if far more insidious, constantly-acting ability. Indeed, she has given it the ability to invoke [an unfair fight that rob heroes of their most precious weapons]. If Saber touches the Noble Phantasm of another servant with it, then their magical power will be negated, reducing them to ordinary weapons only magically-enhanced enough to harm servants. This last until the fight is over. This will obviously not work on Noble Phantasm without a physical form or those with limitless power (in other words, EX-ranked Noble Phantasm). This is a deliberate recreation of his fight with Artoria, where she was forced to fight without Excalibur.
Ironically, if he were to face Artoria again, this Noble Phantasm would be automatically deactivated. Indeed, as she owns the real thing instead of a replica created by the Grail, the falsehood of this Weapon would be revealed and it will itself become a regular sword.
