Why do i need so much more xp to level up

Xp to level graph looks like this:

The Exp you need to level keeps going up every few levels. But after 25 levels it goes back down.

Ya, it's super annoying. Created to add that extra addictive hook. One of the worst things of the blue essence overhaul

wait may someone explain this to me? im lv 50 right now and i need more THAN BOTH OF YOU GUYS HOW IS THIS POSSIBLE!?

It resets every 25 levels. And how many point you need per 25 levels slowly goes up until 150 iirc.

Woa... that's... weird.

THanks everyone
