What is the magic system for this setting?

I'm debating whether actual [i]magic[/i] Magic will be present; if it is, it'll likely be an esoteric and difficult system.

As for the primary "gimmick" power though, that would be [b]Aura[/b]. In this setting, when a warrior attains a certain level of physical/mental/spiritual balance and a certain level of mastery in their chosen art, they can "Awaken" their Aura. [b]It takes the form of a colored (unique to individuals) gas-like "energy" that coats their bodies.[/b] Once one is able to Awaken their Aura at will, they can enhance their physical attributes to become stronger, faster, more durable, etc. However, the amount of Aura one possesses is much akin to cardiovascular fitness---it takes further training to develop it, and overuse of Aura not only tires a person out, but can put dangerous levels of stress on their muscles and bones.

After Aura has been Awakened, however, it can be further refined into a number of specialized [b]Types[/b]. Before the Demon War, it was generally considered impossible to use more than one Type of Aura---those incredibly rare few who could perform such feats were considered irregular existences or legendary prodigies. However, war tends to drive innovation, and when humans learn something is no longer "impossible," it tends to rapidly become more prevalent. After Players begin their Second Life, they may very well reach heights far beyond what was possible before!

The types are:[list][*]Augmentation: The most common type. Coating anything in Aura makes it more durable, better at its function, etc. A sword becomes sharper, a shield can absorb more damage---even a wooden stick could become like a bar of steel. The Aura [b]crystallizes[/b].
[*]Sensation: The least exhausting type, but also considered to be the weakest. One's five senses become superhuman in nature, but one of the five will also become able to detect "life" and Aura, even from a distance. Users of this type can also suppress their own Aura, which makes them supernaturally harder to detect. The Aura's [b]center[/b] becomes a [b]dark shadow[/b].
[*]Shaping: The second rarest type, equally as exhausting as Augmentation. The Aura itself becomes malleable and stronger. Once one has "fixed" a shape in their mind, their aura will take on that physical quality. It could be used to extend the reach of a sword, or to add a dense ball of spikes to the end of a chain, and so forth. [b]Note that a fixed shape can't be changed[/b]. The Aura's [b]texture[/b] matches that which it imitates.
[*]Projection: The second most exhausting type, as rare as Sensation. From a channeled object, the Aura is released over a distance. Using this type with a sword could create a crescent shaped wave of cutting force, or if you covered an arrowhead in Aura you might cause it to release a sort of explosion on impact. The Aura's [b]center[/b] brightens like a [b]white-hot[/b] flame.
[*]Conversion: [b]The rarest and most exhausting type of Aura[/b], it converts one's auric energy into another type of natural phenomenon. One might cause icy frost to cover their weapon and spread from contact, or it might burst into flames. Like Shaping, [b]only a single phenomena can be "fixed"[/b] by the user, but its uses are quite versatile. The Aura takes on the [b]physical qualities of the phenomenon[/b] while maintaining its color.[/list]

[b]Note that I am very open to feedback on this because I know I have a habit of making things overly complex! Any questions, suggestions, and concerns are welcome![/b]
