Linear XP
The Linear XP modification offers a straightforward solution for Fabric servers that fundamentally alters Minecraft's level progression system. Instead of the standard progression where each subsequent level requires increasingly more experience, this mod establishes a fixed experience cost for every level.
The balancing is configured so that the total amount of experience required to reach level 30 remains approximately the same as in the base game version. This means that each level will cost exactly 46 experience points - the same amount needed in the original version to advance from level 17 to level 18.
