The power system of this world follows a simple progression, it isn't anything new.

1. Initial (0-20%)
2. Early (20-40%)
3. Mid (40-60%)
4. Late (60-80%)
5. Peak (80-99%)
6. Half-step (99.n)
Major Realms
SPOILERS AHEAD!!!
Warning!: This scaling is flawed, in some instances it might not correspond to the novel at all, but this is the general progression of the characters. I decided to add my scaling in the end so I might get you fired up for what is coming.
