The five evolution stages are also called:
beginning tier:
01 up to level 500
Basic: 01 to 150
Intermediate: 151 to 300
Advanced: 301 to 500
First evolution
King tier: 01 to 1000.
Second evolution:
Emperor: 01 to 1500!
3rd step
Mythical: 01 to 2000
4th evolution
Legendary tier: 01 to 2500
5th!
Demi-god tier.
After each evolution step passes, the player's level is reset to restart to one before continuing to the next stage.
But the points of the stats and skills remain, also undergoing evolutions in turn.
You will understand more as the story progresses.
Ps: there are some inconsistencies at the beginning, but they are tiny, and those who notice it will be geniuses. Anyway, just to say that they will not hurt history.
For any kind of questions, do not hesitate.
Have a great lecture.
