XP Multiplier
by Prunty
XP Multiplier, a Fabric server mod, scales the experience players gain from every source with one global config value.
What it does
The mod applies a single multiplier to experience gain across the server. Mob kills, mining, smelting, fishing and breeding all feed into the same setting, so one value changes how quickly every player levels up. Owners can raise it for a double-XP survival server or lower it to slow progression in hardcore or challenge worlds.
Because the change is made in one config value, it avoids editing commands, datapacks or the many systems that award experience. It suits modpacks that want smoother levelling, and it lets a server adjust balance later without maintenance work on other parts of the game. XP Multiplier requires Fabric API and is published for Fabric only, with 12 release versions 1.21 – 1.21.11 and the latest file for 1.21.11, released under the MIT License. The mod is not open source.
Key features
Global experience scaling
One multiplier scales experience gain for the whole server rather than for individual sources.
Common XP sources covered
Mob kills, mining, smelting, fishing and breeding all pass through the same multiplier.
Single config value
The adjustment lives in one config entry, so balance changes need no other edits.

How it compares
DropMultiplier scales item drops rather than experience and is a client and server mod under All rights reserved, published for 1.21.11 only. ZoomX Smooth is a client-side only Fabric mod under the MIT License for 1.21.1 – 26.2, so it changes visuals on the player's side and does not touch experience. Sizesteal is a client and server mod under the MIT License for 1.21.7 and is not an experience multiplier.
