What is Clumps Mod?

What Is Clumps Mod?

Every XP orb in vanilla Minecraft is its own entity. A mob grinder or a big smelting session can spawn hundreds of them, and every one has to be ticked, moved and synced by the server.

Clumps Mod fixes that by grouping nearby orbs into a single orb that carries their combined value. Players also pick orbs up the moment they touch them, instead of one by one.

Nothing is lost: the total XP stays exactly the same. You just get it with a fraction of the entities.

Same XP, fewer entities

How It Works

Clumps brings nearby experience orbs together, keeping their combined XP ready to collect.

  1. Orbs Appear

    Activities such as defeating mobs create experience orbs around your world.

  2. Nearby Orbs Merge

    Clumps groups nearby orbs into fewer entities. Each merged orb carries their combined XP value.

  3. Collect Your XP

    Pick up the merged orbs as you play. You keep the total experience with fewer orbs to collect.

Mod vs. Plugin

Clumps Mod needs a mod loader. If your server runs Paper, Spigot or plain vanilla, here are your real options.

Clumps mod Paper

Paper / Spigot: built in

The Clumps mod can't run on Paper — it's a Fabric/Forge/NeoForge mod. But Paper (via Spigot) already merges XP orbs. Raise the radius in spigot.yml:

world-settings:
  default:
    merge-radius:
      exp: 6.0

Restart the server after changing it.

Clumps plugin

A separate “Clumps” plugin

There's a third-party Paper plugin also called Clumps, by InventoXtar. It merges orbs in a similar way but is not made by Jaredlll08 or connected to this mod.

View it on Hangar ↗

Clumps datapack

No official datapack

Clumps is only released as a mod. There is no official Clumps datapack. For vanilla servers, the simplest route is switching to Fabric and adding the mod, or using Paper's built-in merging.

Is there a Clumps mod for Forge?

Yes. Forge builds exist from 1.12.2 up to 1.21.11, for example 12.0.0.4 for 1.20.1. For Minecraft 26.x, use NeoForge or Fabric.
