EXP scales with level so at some point you would stop getting EXP, right?
Would a beginner even be able to reach 250 just on these mobs alone?
Nope, got this from orangemushroom:
Monster experience rates based on the difference in level have been reorganized.
You will now gain more experience from monsters close to your character’s level.
Based on the data from this user on Insoya, I made a graph showing the effect of a level difference on the EXP acquired. At -10 and +10, you’ll get 100% exp, between -9 and +9, you’ll get 105% exp, and between -4 and + 4, you’ll get 110% exp.
When fighting monsters a certain level higher than your character or a certain level lower than your character, the experience and mesos you will receive will be decreased in proportion to the level difference.
Starting at -11 until -40, you’ll gain less and less experience until its 70% exp, continuing until -200.
Starting at +11 until +20, you’ll gain less and less experience until its 90% exp. Starting at +21 , it will be 70% exp and decrease much faster, until it is 10% exp at +32 or higher.
This does not apply to bosses.
