What is Clumps?
Clumps by Jaredlll08 merges nearby experience orbs into single entities worth the combined value. Vanilla spawns one orb entity per XP droplet, and a busy mob farm or a death at level 60 floods an area with hundreds of them, each ticking physics and collection checks. Clumps turns that cloud into a handful of orbs.
Bonus effect: clumped orbs absorb instantly on pickup rather than trickling in one at a time, so standing on a pile of XP no longer plays maraca sounds for ten seconds.
Why Packs Always Include It
- Server tick savings: entity count is a primary lag source; mob farms produce XP orbs faster than anything else spawns entities. Clumping keeps grinder rooms from becoming tick sinks.
- Instant absorption: merged orbs grant their full value the moment one touches you — no pickup delay per orb.
- Zero gameplay change: total XP is identical; Mending and XP-consuming mechanics see the same numbers.
- No configuration needed: install and forget, on Forge, NeoForge, or Fabric, server-side where it matters (clients on vanilla can still join in most setups).
It is one of the highest value-per-kilobyte mods in modded Minecraft, which is why it appears in nearly every pack's performance stack.
Clumps FAQ
Does Clumps change how much XP I get?
No. Orbs merge with combined value; you receive exactly the XP you would have collected orb by orb, just instantly.
Is Clumps server-side or client-side?
The merging happens server-side (or in single-player). Matching client installs keep visuals in sync in modded multiplayer.
