ExpChunk adds a unique XP multiplier system to Minecraft Forge 1.20.1. Each chunk has its own multiplier that gradually decreases the longer it stays loaded, down to a configurable minimum. When a chunk unloads, its timer pauses, and its progress is saved across server restarts.
The mod also includes commands and configuration options to manage multipliers, check chunk information, and customize how the system works. Perfect for servers looking for a different way to balance XP and progression.
