Shil'gon Zayin
Snowfall Sword
Rank: C
Type: Anti-Unit
Sword of Joab. While undercover in Kinsari Saber commissioned a blacksmith for a new sword to replace one that had shattered in battle. Upon the blade's completion Saber asked the blacksmith who he wished to kill with it. When he answered
"Joab" Saber replied
"Suppose I am Joab" and mercilessly killed him with the very sword he forged. According to legend the slice was performed with such speed and skill that the man didn't even realize he'd been cut, only feeling a cold sensation like snow in his belly before his body fell in two.
Reflecting this wounds dealt by this Noble Phantasm won't inflict any pain, but simply a pleasant numbing cold as the target's life slips away, making them imagine a gentle shower of snow falling upon them. A merciful blade that kills without leaving pain or regrets, befitting one who dedicated himself utterly to serving his liege and God. Nonfatal cuts will temporarily sever the opponent's nerves to disable them, as if the relevant part of their body was covered in ice. Saber can also use this ability on himself as a form of anesthetic.
Matsor Al Kinsari
Forty Days In Kinsari
Rank: B
Type: Anti-Barrier/Anti-Mind
A reproduction of the episode where Saber infiltrated the Amalekite capital of Kinsari in disguise to bring it down from within. Even though he went out every night to kill the city's mercenaries by the hundreds, the family taking him in never doubted Saber's innocence until the moment they saw him walk back home holding a bloody blade.
As a Noble Phantasm this carries two separate effects. First is that Saber can bypass any barriers meant to keep him out of a particular place. Locked doors open, keycard-readers register Saber as the intended entrant, even magical defenses like Bounded Fields momentarily dissipate to allow him passage.
The second aspect of this Noble Phantasm is that as long as Saber is somewhere he "shouldn't be", people will subconsciously accept his presence. A subtle mental charm that makes others instinctively perceive Saber as "having a reason to be there", no matter how implausible it might be objectively. For instance assuming he's a janitor in the VIP-only section of an office, or an apprentice at a Mage's workshop. This effect is dispelled if anyone actually witnesses Saber perform an action that contradicts his "role", like killing somebody.
Ashmedai Gilgul Neshamot
Demon-King Incarnation
Rank: A
Type: Support
The buried secrets of Saber's lineage combined with the legends where his ferocity in battle was likened to the demon-king Asmodeus and sublimated into a Noble Phantasm. By embracing these depictions Saber may shed his humanity to transform into a fearsome demon, a veritable avatar of Asmodeus. Upon invocation Saber's skin reddens, his musculature becomes more prominent, his hair grows longer and silvery unkempt, finger-and-toe-nails sharpen into bestial claws and he gains a pair of prominent fangs.
In this form all of Saber's parameters are ranked up and his
Shedim-Kind Demon Skill is raised to A+, granting a variety of powers that stem from his inhuman ancestry. However he also suffers a clouding of the mind akin to B-ranked
Mad Enhancement. The constant roaring of his demonic instincts overwhelms whatever sanity Saber possesses, reducing him to a state where he can only act on his most primitive urges; to kill, to feed, to defile.
Furthermore as an avatar of Asmodeus Saber obtains the Skill
Cardinal Demon (Lust) at rank A, emitting an aura that erodes inhibitions while compelling enemies' selfish desires to rampage out of control. This isn't necessarily sexually but more on the basis of amplifying the target's worst character-faults, like for instance one who hungers for fame might become a raging gloryhound who'd endanger even their own allies in order to get the "first kill".
This effect only lasts in the proximity of Saber/Asmodeus and wears off once the target strays from his presence. Can also be overcome by high amounts of willpower as well as Skills and Noble Phantasms granting mental resistance. As the opposite side of his authority Saber may also call on the whirlwinds that punish Lust in Judeo-Christian mythology, expelling searing gales that strip flesh from bone and send foes flying with every swing of his sword. Due to embodying the human side of Saber's legend, his first two Noble Phantasms are sealed while this one is active.
This Noble Phantasm is somewhat analogous to the "Inversion Impulse" phenomenon held by mixed-blood clans in the Far East, where one obtains greater power by surrendering to their demonic instincts. Following his transformation Saber is unable to disengage this Noble Phantasm's effects on his own, requiring a Command Seal to revert him to normal. As it means taking a form unsightly to his king Saber dislikes using this Noble Phantasm, only doing so when directly ordered by his Master or if he can be sure no one else can see him.
