Writing attempt 3 - power system

Idk, it’s an attempt at making a powersystem that is vivid, lifelike, adds a touch of magic while remaining mostly rooted in logic, has limitations, costs, different uses, wierd quirks you have to consider,backlashes if you make mistakes, the backlash being a natural cause of what happened and not just spitting blood and becoming pale, complex combinations, different levels of proficiency within different categories, an overall substance that fuels the whole system overlaid the mortal world, items neccecary to maintain for some cost that will help you conduce that power, and so on and so forth, if you want to use the powersystem i invent here for your own use, you are free to, aslong as you credit me for it in your synopsis. As for the power scale; it is not confirmed yet, but due to the general knowledge of the world, it is assumed that while excrutiatingly difficult to attain, eternal life should be possible. This is the kind of eternal life where no outside force can affect your lifespan and no inside force can affect it either, you can get pretty close to omniscience, but it will never be perfect, and as for omnipotence? Just like omniscience, it will never be perfect, but you can get pretty close, after all the concept of omniscience and omnipotence are self-defeating. So this power system is for novels with characters that want to be immortal, once you reach a certain level you can’t get off the tigers back, as the chinese sometimes say, this means it’s very hard to stop cultivating if you want to survive, and even still, it is hard to survive even if you want to survive. Uhh there is also a bunch of other stuff there, like just cause i wanted to write and had nowhere else to put it.
