XP Works

XP Works    Updated Description as of 11/1/2026:

Liquid Experience for Minecraft 1.21.1, on NeoForge and Forge. Store your XP in a tank, pipe it around, and collect it from mob farms with a drain.

• Liquid Experience: a glowing green fluid with a bucket. 20 mB = 1 XP point (1 bucket = 50 points), the community standard. It’s in the c:experience tag, so other mods’ XP fluids and machines work with it.
• Experience Tank: holds 100 buckets (5,000 points) of any experience fluid. Tanks that touch join into one big tank, any shape: 10 tanks hold 1,000 buckets.
• Experience Drain: stand on it to pour your levels into the tank below. It also soaks up XP orbs, so it makes a mob-farm collector.
• Works with any pipe mod that moves fluids (on NeoForge: Pipez, Mekanism, Create, …). JEI info pages for every item.

Experience Tank

I G I      I = Iron Ingot
G B G      G = Glass
I G I      B = Bottle o' Enchanting

• Empty hand, right-click: take exactly 1 level.
• Sneak + empty hand, right-click: put all your XP in.
• Buckets in and out. Pipes on all six sides.
• Comparator output: the fuller it is, the stronger the signal.
• Keeps its contents when broken. The tooltip shows how much is inside.
• You can see the fluid level through the glass.

Bigger tanks: just put them together

Tanks that touch, side by side or stacked, in any shape, become one shared tank. Each tank adds 100 buckets.

• Pipes, buckets, the Drain and right-clicks work on the whole group, through any of its tanks.
• A comparator next to any tank reads how full the whole group is.
• The liquid settles bottom-first, with one surface across the whole build.
• Break a tank and it takes its share of the liquid with it (never more than 100 buckets). If that splits the group in two, each part keeps the liquid in proportion to its size.
• Place a tank between two groups and they merge, liquid and all.
• Safe across chunk borders, unloading and restarts: no lost or duplicated XP.

Experience Drain

Shapeless: Iron Trapdoor + Hopper + Bottle o’ Enchanting.

• Stand on it in survival (or adventure) and it drains about 1 level per second. It never drains players in creative or spectator mode.
• It absorbs XP orbs that touch it, merged orbs included.
• It pushes the liquid into the tank (or any fluid block) below it, and keeps a small 4-bucket buffer that pipes can pull from on any side.
• When there’s nowhere left to put the liquid, it stops: you keep your levels and orbs stay on the ground.

Config

serverconfig/xpworks-server.toml in your world folder:

Requirements

• Same features and the same save format on both loaders.
• Install it on both the client and the server.
• Pick the file for your loader: each jar only runs on its own loader.

For mod and pack makers

The fluid id xpworks:liquid_experience and the c:experience tag are stable, and the ratio is 20 mB per point. Any machine that pushes into a fluid handler can fill an Experience Tank.
