DISCLAIMER: This will be updated and changed throughout the story, don't read through if you don't want spoilars after there are about 20 or so chapters as I'll be adding no indication of when the abilities are Acquired.
However the first three will be Acquired during the first chapter so you can read that if you want.
Abilities are classed into levels which are
Low level -> Intermediate level -> Advanced level -> Master Level -> Demi-God Level -> God Level -> Existence Level
Each of these levels is then classed in to small sub-sects
Weak -> Medium -> Strong -> Peak
They aren't dependant of the power itself but based off of the total potential they have, the weaker the abilities at the start, the more they can grow, when reaching Peak at a level it is significantly hard to move it to the next one.
