True Name: Unknown, The Good Hunter

Alignment: Chaotic Good

Strength: B

Agility: B

Endurance: A

Mana: D (A)

Luck: C

Noble Phantasm: E-EX

Class Skills:

Magic Resistance (A) – Cancels spells of A-Rank or below. In practice, the Servant is untouchable to modern magi, so it would not be an exaggeration to title the Servant a "Magus Killer". This skill is bolstered by one of Saber's Noble Phantasms, which is why it has such a high rank.

Riding (N/A) – Saber has never ridden upon any beasts in life, as such she has no ranks in Riding.

Personal Skills:

Eye of the Mind (False) B (EX): Is a natural talent to avoid danger on the basis of an innate 6th sense, intuition, or prescience, where accuracy of instinct has been augmented by experience.

Eternal Arms Mastership D (B): Prevents degradation of fighting skills when under the effect of mental hindrance. Mastership of combat arts has reached the point of being said to be unrivaled in one's era. By complete merging of mind, body and technique, it is possible to make use of full fighting skills even when under the influence of any sort of mental hindrance.

A Great One is a being of strange geometries, unknown to the mind of man. A body built in the image of man would thus be something unfamiliar. But, should the body of man be remembered, other knowledge might be retained as well.

Clairvoyance B (EX): Saber has been granted eyes on the inside and through them sees the world through the lens of the cosmos. At this rank, Saber can see alternate realities or different layers of this one with much focus, revealing that which is hidden or unknown.

The Good Hunter possessed great Insight in life, revealing much that was hidden. Ascending her existence revealed the Eldritch Truth and the Good Hunter was enraptured.

Summoned as merely the Good Hunter grants Saber access to the Insight she possessed before the end of the hunt, granting Saber a (B) rank. However, the Great One the Good Hunter became noticed the brush against her existence and stepped into the pale shadow of her True self, bringing with her the Eldritch Truth of a Great One, however young she may be.

Bravery (A+): The ability to negate mental interference such as pressure, confusion, and fascination. Not only is Saber immune to mental interference; but she also receives a boost to physical parameters and increased melee damage.

In life, Saber fought in the darkest depths of Nightmare and highest of towers brushing the cosmos. She has slain men, beasts, and Great Ones, insomuch as Great Ones can be slain. There is nothing that exists upon this Earth that can make her falter. But then, this Earth is not all that is.

Pioneer of the Stars (EX): The unique Skill given to heroes that became turning points in the human history. All difficult voyages and challenges which are considered "impossible" turn into "events that can be realized."

The Good Hunter transcended Humanity, becoming a Great One and thus uplifted her fellow humans into a "Second Childhood."

Independent Manifestation (EX): Independent Manifestation is a special Skill that permits unsupported manifestation into reality, without necessity of energy cost or of summoning by a Master; effectively, the Skill serves as an enhanced version of Independent Action. Being that the skill holder is signified as a confirmed existence, a resistance is rendered against the instantaneous imposition of death and attacks affected by time manipulation.

Battle Continuation (A): A skill that allows for the continuation of combat after sustaining mortal wounds. It will also reduce mortality rate from injury. It is possible to fight even with deadly injuries and can remain alive so long as one does not receive a decisive fatal wound. Bonus Effect of gaining a high chance of escaping combat and reaching allied territory alive after being defeated.

The Hunters of Yharnam are a unique breed. Those associated with the Hunter's Dream even more so. The Good Hunter is capable of fighting until her body no longer functions and perhaps even then.

In a normal summoning, that would be her limit. However, as her body is tied to her Great One self, she may even be capable of fighting past death, for the death of a Great One is a queer thing.

Hunter of Beasts (B): In her legend, the Good Hunter fought numerous victims of the beast plague, from new hunters drunk with blood to powerful hunters fully lost to human form, all fell to her blades. The Good Hunter receives a single increase in rank against any beastly opponent or consumer of blood.

Slayer of Great Ones and Kin (B): As with beasts, Saber fought against Great Ones, their worshipers, and many who attempted to become or partially succeeded in becoming Great Ones themselves. All fell to her blades, even if she herself fell many times to them. Saber gains a rank up against any enemy classified as Kin, Great One, or possesses sufficient knowledge of the Eldritch Truth as to make little difference.

Noble Phantasms:

Hunter's Toolkit (E-A): A collection of tools, both weapons and artifacts used by the Hunter in life. This includes numerous trick weapons, multiple arcane focuses, magical gems, firearms, and runes.

Hunter's Dream (A): Were the Good Hunter to be summoned in a standard fashion without a connection to her Great One self, the Hunter's Dream would manifest as a dream plane, home to the Hunter's Workshop. As the Hunter is bound to the dream, she may create a small number of lanterns linking her to the Dream. Upon death, she would return to the Hunter's Dream in a weakened state. However, as the Great One the Good Hunter became is aware of the copy of the Good Hunters human form summoned to fight in the Grail War, the Hunter's Dream instead links to the location where the Ascended Great One truly exists. The Good Hunter will instead return immediately to full strength at the nearest lantern or at least once she figures out how to do so. As few have sufficient eyes to see the Great One manifest, there are not many who might notice her return.

Childhood's Beginning (EX): Before the night of the hunt was over, Saber had consumed three Third Umbilical Cords, granting her great Insight. When she refused a quiet ending to the hunt and cut down the first hunter, a fitful presence descended from the moon. This presence too was slain, and in doing so, Saber ascended into something more, becoming in truth what many had failed to be, rising past Kin and becoming a Great One herself. When the Grail created a copy of Saber from the Throne of Heroes to fight in the Grail War, it caught the attention of the adolescent Great One the Good Hunter became. As such, the Good Hunter reached into the summoned Saber, functionally making her the true Good Hunter, fully empowered by a being far beyond what humans or even Servants could comprehend. In effect, Saber is no longer limited by her master's prana, but by her own abilities and skills as a Hunter and as a Great One. She is sustained by her Great One self, and may manifest abilities not expressed by her legend due to the touch of a being whose abilities can still grow and change beyond a previous legend.

I'm not quite going to say this is open for debate, but if you think any of these are blatantly and massively wrong, let me know as well as why you think so. The rankings for FSN are kind of weird to try to figure out.
