It seems you possess the blood of the Uzumaki, a now decimated but once proud and enigmatic clan descended from Asura himself. The Uzumaki were provided incredible abilities through their bloodline of which you have also inherited, but you are no mere member of the clan. Instead you're a paragon of the Uzumaki, their equivalent of Hashirama to the Senju, or Madara to the Uchiha.
You now possess a much more powerful body and life force, granting you effective immortality and regeneration on par with Madara’s after he absorbed the Jūbi, and your chakra capacity and quality has been increased by a factor of 4.
Your chakra has also gained certain properties alongside it, now a lot more dense you can manifest your pure chakra as constructs and you can now channel any unique properties your chakra possess. You start off with the skill and mastery of utilizing your chakra constructs as chains but are by no means limited to it.
Alongside the potency of your chakra, the Uzumaki were known to possess unique qualities within their chakra, such as Karin’s healing, Kushina’s ability to absorb and bind, and more. You can freely modify your chakra properties such as absorbing others chakra or being poisonous at will. You can learn over time to hold multiple chakra properties at once but are only capable of imbuing it with one property to start with.
And now finally the Uzumaki’s greatest skill, the one ability which caused other nations fear them so that they banded together to destroy them, Fuinjutsu. Seals are a unique conundrum in the Shinobi world, do they merely store things or can they do everything just in written form? For you it is very much the latter, you are now capable of with time, research, and practice, capable of doing anything with seals. You have the innate ability to understand the nature and language of seals, able to decipher, read, and write in it as easily as breathing. You start off knowing how to replicate any effect you can produce, whether through your body, powers, chakra or anything else but you can do so much more. You can do anything you put a modicum of effort to.
