# XP Multiplier
**XP Multiplier** does one thing and does it properly: it changes how much experience you earn. One number for mob kills, another for everything else — enchanting, mending and repairs stop being the bottleneck, or become a real one if you turn the rates down instead.
Everything runs **server-side**. Players join with a vanilla client and get the full effect: no client mod, no resource pack, no config sync.

## Features
### 🎚️ Two rates, or one per mob
Mob kills and the rest of the game are separate settings, so you can quadruple mob experience without touching ore or furnace output. Then override any mob that deserves its own rate.
```json
"multiplier": 2.0,
"other_multiplier": 1.0,
"per_mob": {
"minecraft:enderman": 4.0,
"minecraft:blaze": 3.0
}
```
### 🌍 Every source, not just mobs
`other_multiplier` covers **ores**, **furnaces and smokers**, **fishing**, **breeding**, **villager and wandering trader deals**, **grindstones** and **thrown bottles o' enchanting** — because they all award experience through the same place in the game, and none of them was left out by accident.
### 🎲 Fractions actually work
A rate of `1.5` isn't rounded away. The whole part is guaranteed and the remainder is a chance, so 7 experience at 1.5× pays out 10 points half the time and 11 the other half. Over many awards that averages to exactly 1.5× — any single award is a coin flip rather than a promise, which is the honest cost of allowing fractions at all.
### 📉 Or make it harder
Rates go down to `0.0`, not just up. Halve every award for a slower server, or set mob experience to `0.0` and force players to earn levels from ores and trades instead. The same fraction handling applies, so `0.5` is a genuine coin flip per award rather than a rounding rule.
### 🚫 Blacklist and boss safety
The **ender dragon** and the **wither** are excluded by default, because a single kill worth thousands of points is exactly the wrong thing to multiply. Delete them from the list if you disagree — nothing is hardcoded.
The dragon is a genuine special case: it hands out its experience during the death animation instead of the usual drop, which is how it slips past most mods of this kind. It is handled explicitly here, so blacklisting it actually works and a per-mob rate for it actually applies.
### 👤 Player kills only, or everything
By default only kills **credited to a player** are multiplied. Vanilla already withholds mob experience unless a player damaged the mob recently, so this mainly decides what happens to the finishing blow — turn `require_player_kill` off and a mob a wolf finished for you still counts.
### 🛡️ Never duplicates a player's levels
The experience a player drops on death is a slice of what they had already earned, not a fresh reward. Players are excluded unconditionally — there is no config option that can turn dying into a way to print levels.

## Commands
| Command | Permission | Description |
| --- | --- | --- |
| `/xpmult` | level 2 | Shows the current settings and the config file path |
| `/xpmult status` | level 2 | Same as above |
| `/xpmult set ` | level 2 | Changes the mob experience rate and saves |
| `/xpmult other ` | level 2 | Changes the rate for every other source and saves |
| `/xpmult enabled ` | level 2 | Turns multiplication on or off |
| `/xpmult reload` | level 2 | Reloads the config after hand-editing the file |
---
## Installation
1. Install **Fabric Loader** and **Fabric API**
2. Drop the jar into your `mods` folder
3. Start the server — `config/xpmultiplier.json` generates on first launch
Required on the **server only**. Installing it client-side in singleplayer works just as well (singleplayer runs an internal server).
---
## Configuration
The file lives at `config/xpmultiplier.json` and is written with a comment header explaining every option.
```json
{
"enabled": true,
"multiplier": 2.0,
"other_multiplier": 2.0,
"require_player_kill": true,
"per_mob": {
"minecraft:enderman": 4.0
},
"blacklist": [
"minecraft:ender_dragon",
"minecraft:wither"
]
}
```
| Field | Meaning |
| --- | --- |
| `enabled` | Master switch. `false` means vanilla experience everywhere |
| `multiplier` | Rate for mob kills without a `per_mob` entry. Fractions are honoured as a chance |
| `other_multiplier` | Rate for ores, furnaces, fishing, breeding, trading, grindstones and bottles o' enchanting. `1.0` leaves them alone |
| `require_player_kill` | Only multiply kills credited to a player |
| `per_mob` | Per-entity rates, keyed by entity id. Overrides `multiplier` |
| `blacklist` | Entity ids that are never multiplied, whatever else is set |
Reading is lenient, so you can keep your own `//` notes in the file — they are dropped the next time the file is rewritten.

## Compatibility
- **Minecraft:** 1.21 – 1.21.1, 1.21.9 – 1.21.11, and 26.2
- **Loader:** Fabric
- **Dependencies:** Fabric API
- **Side:** server-side (clients need nothing)
- Works with modded mobs: rates are keyed by entity id, so any mod's mob can be given its own rate or excluded
- Modded experience sources are multiplied too, as long as they award experience the normal way — they land under `other_multiplier`
