TAEL/Abilities

Recollection of a Bygone Past
TAEL retains all the abilities from his previous self and from his Completed self, although he is unable to access a number of those due to his body being permanently incomplete. He can however, no longer use his racial abilities as he used to, instead being replaced wit a similar effect, but with radiant, ever glowing golden light. Some of these moves however, have gotten a large upgrade compared to their previous incarnations due the influence of the Divine Core of the Erdtree.

Lesser Hellblaze -> Loathe
This immense growth this ability has gone through is quite noticable, from appearence, to potency and use. Loathe is a conflagration of deep crimson flames with a thick outline of vanta black which has the ability to burn forever and ever, even after the user has stopped casting it's spell and has lost focus, being often associated with the flame of a deep hatred, never satiated, forever wanting more and more of the body it consumes. Burns from this flame will leave a mark of the same color as the flames on the opponents body, leaving them with an image no different then Oddity Tael' s current left side on whatever body part was burnt or burnt out with it.

Blood Magic: Kreuz -> First Ichor
Another ability that underwent a massive change is Tael's Kreuzblut, his very own style of Blood Magic which ascended beyond mere crosses, and can now be used offensively to control the blood of his opponents upon contact and control his own to minute detail. It has been since named The First Ichor, since it not only works on blood, but it also works on whatever the target's body uses instead of actual blood.

Blackest Night -> Morning Star
Blackest Night used to be the main method of Spacial Magic associated with Dark Cast that Tael owned into one. Since Tael's affinity no longer aligns with the Dark, his body has developed a new form of ability - The Morning Star. Essentially, The Morning Star grants Tael the ability to control gravity and summon forth exact copies of Astral Bodies as he wishes, to whatever proportions he desires, aswell as controlling existing celestial bodies as he pleases through the use of this ability.

Master Curse Weaving -> Eldritch Truths
Due to Tael's touch with being an Eldritch being as of recent times (Refer to literally being CT, an Eldritch God of uncanonical make) and his already large experience with curses and madening spells, he has gained the ability to instil the truest form of Eldritch Fear or even insanity in ever the most stoic and resolute of minds, essentially acting as a stun to the opponent or even as a means of true intimidation or to create openings. Even if the opponent is unable to be feared, specific moves of this art will be able to paralyze at a gaze, such as "Eldricht Glare", which cramps the muscles of the opponent and tries to send visions of Eldritch Nightmares to plague their very mind.

Thunder Nen -> Might of the Golden Thunder
Might of the Golden Thunder is a large upgrade to Thunder Nen, which required the user using the Nen principles to be used and pretty much fell off compared to Thunder magic. Might of the Golden Thunder is perhaps the most destructive weapon on his kit, save for his Explosion magic, being able to rupture through cities with the poewr of bright white Thunder. This specific brand of Thunder is unique to Tael, achieved through blending the principles of the Golden Law and his own abilities.

Vow of Mastery
Through the power of speech and unnatural charisma, he is able to have even the world listen to his pleas and orders. His incantations become truths that must be followed through, sometimes even going directly against the logic of the world. He can, however, only give these orders to the people of Caelum and that are attuned to the Erdtree (THAT DOES NOT INCLUDE PEOPLE BRANDED BY THE BRAND OF GOLD)

Elementary Trichotomy
An evolution to the See-Through World ability that Tael owned - This allows Tael to not only visualize his opponents blood-vessels, muscles and organs to excruciating detail, now he is also able to see one's soul and it's properties to extreme detail, aswell as their Mind, being that what he considers to be the "Truest Trichotomy of the Self"

NOTE FROM TAEL: By "Seeing their Mind" it means not delving into memories of entering one's mind-space or even reading minds, it means that TAEL can identify what the opponent is going to do to him by reading their mood and state of mind, think of it as TAEL contacting your inner self without meddling with memories or reading what you are thinking.

The Golden Law - Perfection
The Golden Law is a concept that is quite mysterious, but it is clear that TAEL can use many of it's principles, one of which is the principle of Truest Perfection. Such principle allows for a concept to be brought to it's utmost top limit. A dull sword would be able to cut through all matter, a broken hammer would become unbreaking, what is imperfect shall become of utmost perfection with this ability.

"For the Golden Law does not allow imperfections, for everything in Reality is perfect in it's own way"

This ability is part of the abilities granted onto TAEL by the Golden Law as it's true current "Master".

NOTE: Joshua is now the only person that is completly unaffected by the Golden Law save for Tael, for he is one of it's writers on an age that is now timeless

The Golden Law - Loyalty
The Golden Law is a concept that is quite mysterious, but it is clear that TAEL can use many of it's principles, one of which is the principle of Everlasting Communication. Such principle allows for telephathy regardless of distance, as long as one is branded by the progenitor of the Golden Law with the Brand of Gold. This brand is incapable of tracking anyone's location.

"For the Golden Law shuns betrayal, and maintains loyalty amongs it's foundations"

Golden Law (EX+++) (Progenitor)
Due to the fact TAEL is the Progenitor of the Golden Law, it's maker and bearer both, it is clear that he would have this skill, which allows him to use all the Principles of the Golden Law without any drawbacks whatsoever.

Mystic Eyes of Oblivion (EX) (Creator)
Being born with eyes unlike to any other, with powers beyond imaginable.

These eyes grant the user the ability to bring back to life people who were not fully forgotten by the masses of reality itself, and kill whatever he perceives as still living, object, concept or person. Of course it does not bring the person back to life like they were before, they body is just "reactivated" with a hollow soul, because no spell in the world, no matter how strong it is, can completely resurrect a soul already broken and lost, using what people thought of them to only recreate the person. Essentially, TAEL owns the power to create Oddities or revive anyone that has not been yet truly forgotten by the world.

Universal Bird's-Eye View (A+) (Magic)
Universal Bird's-Eye View is essentially the ability to see and understand everything ongoing within a territory within a certain category, in this case, the user can essential see and understand everything ongoing about Magic within a territory, being one of the most hightened forms of Magical Sensibility. This skill, at a A+ level, has a vast territory of an entire planet or even a dimension if the user so wishes.

Divine Core of the Erdtree (A)
This is a skill shared only by two people, and it is greatly connected with the conditions of TAEL's rebirth and the Golden Law itself, being what released it in the first place onto the realm of Caelum. Due to not yet being shown, it will be discussed further on. For now, keep in mind that this grants the user with unrivaled, insurmountable magical power on the border of Infinity

Denial of End (EX)
Denial of End is an ability unique to TAEL, which allows him to never truly die aslong as even a singular person or creature in reality retains a memory of his existence, pretty much giving him atomic to quark-level regeneration even if his body completly destroyed or erased, which is only possible due to the aformentioned skill, Divine Core of the Erdtree and the Golden Law. This however, can also be seen as a terrible curse, for he cannot die and his soul will never know True Respite in his neverending journey. Curse of the Eternal Learner is exactly the same skill as this, but viewed in a darker light, on how this skill prevents him from reaching his great desire.

Blessing of True Void/Radiance (EX+)
Due to being the off-spring of the very Avatar of Divine Radiance and Great Void, he is able to control both elements with relative ease without sparing almost any energy on the process. He is also able to override the control of anyone who uses these elements, as those spells would become his own.

Bearer of True Worldly Perfection (EX+)
As it should be obvious, this was granted to him upon birth due to the creation of the Golden Law, effectively turning Caelum into a semi empty paradise in it's wake with The Shattering, and not due to any other feat or spell he has or will have achieved in his life.

Epoch
Nobody really knows what this does, but TAEL claims that this is his Noble Phantasm, original to his spirit, and he has yet to divulge anything else about it except for two very loose incantation of it"Stars; Cosmos; Gods; Animus; Antrum; Unbirth; Anima; Animusphere""O imaginary gods... I hereby declare the victory of The World. From the deep sea of souls, from the farthest reaches of all existant and non existant, from the depths of our collective mind, let all become aware; our story is filled with blessing! Epoch!"

Trivia

 * The Golden Law is based off the Golden Order from Elden Ring, and to an extent, so is the Erdtree and Caelum as a whole.
 * Loathe is based off the flames of the Black Blade, from Elden Ring
 * First Ichor is based of Kekkai Sensen's entire blood arts
 * Mystic Eyes of Oblivion as a reference to the Mystic Eyes from TYPE-MOON, Fate, as is most of the skills that have a "scale"
