The world contains many dungeons that are spread around the globe.
These dungeons are the home of creatures and monsters that were never seen by humans until 5 years ago.
In these dungeons, humans can obtain powers and items that can help them in fighting the monsters.
However, to obtain such things one has to enter the dungeons and fight.
Fight with the creatures and kill them.
That's the only way.
But, for that, one first has to understand the different kinds of dungeons and their difficulty.
Because not all the dungeons are the same.
They are categorized into three levels.
Low, High, and Super.
However, the difficulty of each category is not the same.
The lowest one is the low category and it is composed of D-Class and C-Class dungeons.
Then, there is the High Category and it is composed of the B-Class and A-Class dungeons.
