[Since you have reached level 90, the experience points you need to level up will greatly vary.]
[Level: 90 (16,400/3,000,000)]
The experience points required right now were actually not bad, but for example, it would likely take an additional 200,000 experience points for level 91 instead of only 100,000 with Leon's curse active.
Then for level 92, it might be 400,000 experience points, and so on, the requirements growing exponentially with each level.
Leon didn't care much though, because he had other ways to grow stronger besides just leveling up, and his focus was on overall power rather than just numbers.
His experience points gains were slowing down drastically, but if he kept going, he could still manage to reach higher levels eventually with enough time and effort.
And leveling up quickly wasn't his main goal to begin with, he simply needed to be stronger overall to face the challenges ahead.
