The * sign marks servants that are completely unchanged from canon. Will also appear on canon noble phantasms and skills in other stat sheets to avoid repetition.

^Not going to be revealing phantasms for now because some will be spoilering, and because I have to tweak the others a bit. Skills and stats are a-go though.
Thank you, RavingScholar and Mook91 for creating stats sheets for the non-canon servants. Honors to Mook for creating the majority of Zealot Hassan's new Zabaniyas.

Class: Assassin
Alternate Classes: Berserker
True Name: Jack the Ripper
Alignment:Chaotic Evil

Parameters
Strength:
B
Agility: A+
Endurance: C
Mana: C
Luck: D

Class Skills
Presence Concealment (A+): It is possible to disappear completely and become almost impossible to be detected, even their heartbeat quieted. However, efficacy will decrease once preparations to attack are taken.

Personal Skills
Eye of the Mind (False) (C): A natural ability to sense and avoid danger. Assassin, in life, regularly made use of her innate sixth sense to survive in the dangerous warrens of London. She has a good chance of reading enemy enemy's moves and can sense most lethal blows so long as the attacker is within line of sight. Surprise attacks against her have a lower success rate inside of combat, and a slight chance of being sensed outside of combat.

Information Erasure (B): After battle, all information about Assassin, including true name, abilities, and appearance, are removed from all witnesses, even opponents. Evidence of the battle however does not disappear, and identity may be deduced through logical deduction.

Mental Pollution (C): Provides a probability that mental interference magecraft will be rendered ineffective.

Murderer of the Misty Night (A): A skill associated with Jackie's nature as a serial killer rather than as an Assassin, which permits preemptive strike against all opponents. Provides unconditional success of the skill at night. Requires a successful Luck Check for use during daytime.

Surgical Procedure (E): Despite the techniques being 100 years old or older, and somewhat unreliable by visual appearance alone, the procedures manage to attain their intended effect, boosted somewhat with application of prana.

Class: Assassin
Alternate Classes: Archer
True Name: Simo Hayha
Alignment:True Neutral

Parameters
Strength:
D
Agility: C
Endurance: B
Mana: B
Luck:A

Class Skills
Presence Concealment (A+/A++): It is possible to disappear completely and become almost impossible to be detected, even their heartbeat quieted. However, efficacy will decrease once preparations to attack are taken. Receives a bonus when surrounded by white material such as snow.

Personal Skills
Clairvoyance (B): Superior visual acuity: Assassin is able to see up to 10 kilometers away, including extreme detail.

Instinct (C): The ability to "feel" the most favorable direction of battle. At this rank, the skill is used by Assassin to determine whether or not an attack will be useful at the time, and deciding whom to attack.

Protection from Ice (A): Assassin withstood subfreezing temperatures for days with only mundane protection. Any ice- or snow-based Thaumaturgy cast at him is greatly reduced, or even negated entirely if it is weak enough.

Tracking (C): Grants Assassin the ability to find Servants with Presence Concealment (D) or less. With a successful Luck check, he can find those with Presence Concealment of higher ranks.

Noble Phantasms

While lacking special properties, Assassin carries a Mosin-Nagant sniper rifle and a machine gun capable of harming Servants.

Class: Assassin
Alternate Classes: None
True Name: Aabidah
Alignment: Lawful Neutral

Parameters
Strength: C
Agility: A
Endurance: C
Mana: B
Luck: D

Class Skills
Presence Concealment (A+): It is possible to disappear completely and become almost impossible to be detected, even their heartbeat quieted. However, efficacy will decrease once preparations to attack are taken.

Personal Skills
Bio-Analyzation (A): A natural gift Assassin was born with. She has the ability to analyze biological components within a certain distance. The closer it is and the more time she spends near it, the greater her understanding of the target's components becomes, to the point of near-molecular comprehension. It has a maximum range of ten meters, while touching the target grants complete knowledge of its biology. Also grants a Presence Detection of a high enough rank that requires conceptual effects to avoid her senses, but only within a range of ten feet. Originally, it was only for flesh-and-blood entities, but upon ascension as wraith then a servant, it is now usable on fellow servants and spirits.

Mental Pollution (C): Assassin has the incredibly distorted worldview of a true zealot. Greatly reduces mental interference Magecraft, but makes her hard to understand save for others with an equal rank of distortion.

Projectiles (Daggers) (B): Thrown daggers are now comparable to bullets.

Self-Modification (A): In a few years, Aabidah made her body capable of accommodating the Zabaniyas of the first eighteen Hassans, each of which was an ability gained through a lifetime of trial and error. Though it is unknown whether she can push her body even more, if given reason, there is no doubt she can do similar things to others.

Surgical Procedure (B): Though a trained killer, Aabidah is a learned woman, whose strange power led to startling leaps in medical knowledge surpassing the modern age that were unfortunately lost to time. The medical techniques possessed by Aabidah are beyond the means of current medical technology; procedures that are currently only theoretical can be performed by her with a high chance of success provided she has the chance to set up a secure room to operate in.

Noble Phantasms
Zabaniya- the Eighteen Deaths of the Mountain Men
Rank: Varies
Type: Varies
Assassin modified her body to contain the Zabaniyas of the Hassans who came before her. Though some might be a bit different in use (such as Delusional Heartbeat being of a lower range and actually a third arm she attached to her back), they are fundamentally the same. As such, Aabidah, for all intents and purposes, contains the equivalent of eighteen noble phantasms of the Hassan-i-Sabbah in her body.

Zabaniya: Delusional Heartbeat (C rank) Number 13
Type: Anti-Unit
Range: 5 m

Zabaniya: Delusional Heartbeat is the arm of the evil spirit Shayṭān, the cursing hand of the Middle East magecraft specialized in curses, it emerges as a third crimson arm extending from her back. The arm's ability is one of the purest magics and simplest curses. It creates a mirror image of the heart of the assassination target with an ether clump, a dual existence that resonates with the original one. By crushing the fake heart, she can crush the real one with this curse without laying a finger on it. It is also possible to switch the two existences by touching the target's chest, allowing Assassin to devour the heart and gain the opponent's intelligence.

The ability completely neutralizes all physical barriers and armors by only interacting with the fake heart, meaning that all physical defense and distance is rendered meaningless. It would simply bypass an armor with a defensive rating of one thousand, and directly deal damage. The way to resist the curse does not fall under endurance, but rather, the target must simply stay out of True Assassin's range and have a high enough magic statistic to prevent the overlaying existence from even being created or have high enough Luck to avoid it without any problem. It can be considered a convoluted and indirect way of kill a target that is more akin to trick used by a magician. The ability, bearing the name of a fallen angel, is only able to target and punish humans. It is unable to curse its own kind, rendering it ineffective against evil spirits or those affected by their curses.

Zabaniya: Ichor of Reverie (D++ rank) Number 14
Type: Anti-Magus
Range: 15 m

Zabaniya: Ichor of Reverie is a Magus Killer technique. Thanks to special modifications to her body Assassin can release special pheromones that will cause a magus to lose control over their Magic Circuits. Once Ichor of Reverie is activated a pulse of prana will be sent throughout the pheromones that Assassin has previously released and any magus who breathes them in will suddenly have their Magic Circuits channel several thousand times more prana than they can safely channel. In addition to completely destroying their Magic Circuits beyond any form of repair the sudden burst of heat will also cause the magi's body to spontaneously combust and they will swiftly perish from the combination of burn injuries and mutilated Magic Circuits.

Zabaniya: Blood of Metamorphose (C+ rank) Number 17
Type: Anti-unit

Zabaniya: Blood of Metamorphose was developed by the seventeenth Hassan, who, alongside his incredible skills typical of the Hashashin, was an avid scholar of the workings of microbiology. Specifically, viruses. He modified his body to produce blood that at any moment could change into viruses whose form and properties he could change at will to suit the situation. This meant that not even poison-immune enemies could last, as he could change the virus into a heterofore unknown breed that they could not defend against. A single drop of blood into the target's food or something they regularly came into contact to thus ensured death.

Aabidah improved upon this even more by gaining the ability to actually direct the viruses even after application. This is possible only due to her Bio-Analyzation ability, which lets her 'see' the viruses even after separating from her body.

Zabaniya: Delusional Lance (E rank) Number 10
Type: Anti-Unit
Range: 5m max

Zabaniya: Delusional Lance was developed by the tenth Hassan, a man who valued basic skills more than flashy special abilities. Since developing a Zabaniya was necessary in order to gain the position of Hassan he created a Zabaniya that just barely possessed the traits required to be called a Divine Miracle. Despite the fact that his competing candidates possessed superior Zabaniyas he still attained the position due to his superior skill and intellect. The Delusional Lance is nothing more than the ability to make one's nails (both on hands and feet) extend rapidly to a variable length in order to pierce or slice an opponent. While the nails are abnormally sharp and capable of cutting through steel like paper, they are not especially durable and can easily be broken by more powerful phantasms and the application of superior strength, although the stumps can easily be lengthened back to proper conditions as long as prana lasts.
