Improved Level Curve and EXP Mod is an add-on that makes the leveling-up process more balanced and gives players more experience points for the same level of difficulty. 

This addon is based on a simple idea: if you level up, your experience should increase as well. However, it's not as easy as it sounds, and there are a lot of details that you need to consider.

The main idea is to add more complexity to the leveling process. For every level of difficulty, you need to complete a specific task in order to gain experience points.
