@Isaiah Cockerham ... Already knowing? You don't know anything, you didn't read it and by now it's obvious you're incapable of understanding mathematics. It says in the first 3 chapters that the monster provides 1,000 xp and it not enough after level 1 because it gives less than 1%. Everyone knows the exp doubles for everyone who has a legendary or unique class. That is except for MC, up until level 10 he is the same, exp requirement doubles. Chapter 3 is where you can derive the equation for triple exp requirements. Chapters 1 and 2 show his leveling before 10. You can calculate the 512,000x3^(Level-10) by the exp the goblin gives and what MC says about the triple requirements
