(From MC Perspective)
I got a good understanding about the system. The System said it will help me to achieve Peak Existence. And its work is very simple. It can raise talent level, for that all I have to do is to make sure to reach that condition. By consuming rare and precious treasure or something related to that.
Other than that the system doesn't have any failure rate while having breakthroughs. That's why it mentioned it can level up the limit. Then the third main ability is also omnipotent. I can use 'n' number of spells without having limitations.
After having some clarity I glanced at another section. My basic stats have increased. The limit cap for Mage at each level is 100. Even if I reach 100 stats in my strength in level 1 Mage. Unless, I met with a condition for breakthrough. It's impossible to level-up just because my stats reached 100.
