Here is how the power system looks:

Apprentice levels 1-20

Intermediate Levels 21-40

Expert levels 41-60

Master levels 61-90

Grandmaster levels 91-100

After you hit 100 there is a trial given to everyone and once they do they tier up

There are 5 tiers which are considered the mortal limit by the Gods (there are rumored to be more than 5 but none have broken the mortal limit) and for humans they are also given the chance to evolve into higher beings depending on their bloodline. After get to tier one they are slowly adapting traits from their bloodline till they change into what ever their bloodline is as they level up to tier two and from there they can still evolve to the limit of their new species. For example if they have an Elven bloodline they will slowly change into one as their ears and skin tone start changing or becoming more fair and so on.

After you hit tier one it's noted to be a little harder to even level up more and hit the next tier everytime you tier up. Those that say that are lazy though. There is only a small handful of people that are above tier 5 and are known as A or S ranked powerhouses. After you hit tier 5 then it goes from E—SS. After SS that is the realm of the gods. It is very difficult to break that wall that separates mortality from the Divine Realm.

Also there are various types of elements tied to ones bloodline or class.

Light - White

Darkness - Violet

Fire - Red

Water - Blue

Wind - Green

Earth - Brown

Space - Silver/Grey

Time - Yellow

Gravity - Purple

There are also various sub elements that one can gain as well but you'll find out through the novel. Now the brighter the color during an awakening the stronger connection to the element you have and vice-versa for the dimmer it is. Also to note Space, Time, and Gravity are all extremely rare elements that only a very rare few have ever gotten through the entirety of the world life. Lastly you should know that you can gain a second element from your bloodline if you are lucky besides just the one from your Class if you even get one.

The sub elements are as follows:

Light - Life and Holy

Darkness - Shadow and Death

Fire - Lightning

Water - Ice

Earth - Nature and Metal

Wind - Sound

Space - None

Time - None

Gravity - None

That is what is known by the world so far and the reason for the last three not having any is that no one knows what they could be due to the rarity and secrecy of each element. There are probably no sub elements due to how powerful the element already is.
