The leveling system is divided by 6 known class rank, There are some beings that are powerful enough to break the highest class rank that is known for people and they are called the ascenders or the transcended beings.
The E class was known for the lowest class as it's territory was in Level 1 to Level 50, Most of the class E adventurers were soldiers and 50% of the total population of adventurers came from them.
The D class was known as the real adventurers since all of them tried to do go as far as to fight D class monsters which were unreasonably powerful. This class was called the tribulation as many adventurers died here.
The C class was the Elite class as most of them succeeded in the D class and this made them strong and powerful.
The B class was called the master class as all of them had their own techniques made by experience and were powerful enough to roam the galaxy.
The A class was the most powerful class that could be reached by the ordinary man. Most of them stopped their progressed and built an organization to have a good life. All of them are prideful and arrogant but they had the power to back it up.
The S class was the highest class that could be reached by using conventional methods such as leveling all of them are powerful that if they use they're all strength in one attack. Their attack is so powerful that they could simulate the power of the asteroid that killed the dinosaurs. but most of them don't use their full power as they would get exhausted and if the enemy is alive then they would be doom.
The last class but wasn't included in the 6 known class was the Ascended or Transcendence class. Most of the beings that achieve this class were powerful that they could slap a planet to death but most of them were known leaders of each race or empires.
-----------
The attribute distribution of each class is different.
The E class would get 2 to 5 attributes for level but some can reach 10 via bloodline. The level of E class is level 1 to 50
The D class would get an average of 20 to 50 attributes but as I said some could reach 100 attributes per level via bloodline. The level of D class is level 51 to 100.
The C class would have an average of 100 to 250 attributes per level and as I said some could reach 500 via bloodline. The level of C class is 101 to 200.
The B class would have 400 to 1000 attributes in each level and like normal some could reach 2000 attributes in each level via bloodline. The level of B class is 201 to 400.
The A class has an average of 1200 to 3000 at each level and I'll say it again some could reach 6000 attributes per level via bloodline. The level of A class is 401 to 800.
The S class or the known final class with an average of 12000 attributes per level and 30000 each level and For the sixth time some could reach 60000 attributes via bloodline. The level of A class is 800 to 999.
The ascended or transcendence class had no limit but each level is 12000000 and 30000000 attributes with the assistance of bloodline the attributes could reach 600000000. The level is 1000 to No known limit. Leveling this class is very hard only some could level the class but the highest was 1005. It came from a very crazy demon lord that killed many demon lords in hell but was stopped by the leaders of other races ganging up to him. (This was why they could slap a planet to death.)
