The main methods in harnessing ain were divided into three:
Aura, the act of expunging one's own inner spirit. It is driven by emotions and several other mental factors. The stronger the mentality of the person using aura, the stronger the aura they can control.
Aura is the hardest method to be used as only a few could harness this power, some are only able to create objects using their aura others could go as far as to make their aura intensify around them to the extent that relics lose their powers temporarily.
The next method is doping which is further divided into three.
In speed doping, the user gathers most of his/her ain to boost their reflexes and movement speed.
The stronger the ain of the user, the faster they can go.
In hard doping, the user hardens their very skin to tank powerful attacks with ease. Some even go further to combine hard doping and power doping to create powerful attacks.
