XP Config
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
XP Config
Adds configurable multipliers to various xp sources.
Configuration
You can configure multipliers in the config file: `xpconfig-server.toml`. It appears after the first visit to the world. (If you use a number less than 1 in the configuration, for example 0.6, you can reduce the experience gained).
Formula: vanillaExperienceGained * youreNumber in config.
Right now, you can change the following experience multipliers for:
- **Ore Mining
- **Mobs
- **Smelting, Blasting, Cooking
- **Fishing
- **Villager and Wandering Trading
- **Xp bottle
- **Fishing
- **Advancements
- **Grind Stone
- **Mob Breeding
