Crystal Speed
by cutebow
With Crystal Speed installed, the end crystal rotation on the client can be tuned for each part of the crystal, from the outer glass to the core.
What it does
Crystal Speed lets the rotation of an end crystal be changed separately for its outer glass, inner glass and core. Each part has its own speed and direction, and a value of 0 stops that part from turning. A bounce speed setting also adjusts how the crystal moves up and down, and parts can be skipped from rendering when they are not wanted.
An orbit tab in the settings can spawn small crystals that circle around the main crystal, with a setting for how many appear. The settings are reached through Mod Menu. The mod works alongside a crystal opacity mod, which makes crystals see through, and the author notes that it draws its rotation idea from Custom End Crystals. The author has said more features may come later.
The mod is client-side only, so players install it alone and servers do not need it. It targets Fabric, with builds for the 12 release versions from 1.21 up to 1.21.11, and the latest file is for 1.21.11, published on 2026-03-07. It is released under All rights reserved and is not open source.
Key features
Per-part rotation speed
Outer glass, inner glass and core each take their own rotation speed, so the parts can turn at different rates.
Direction and stop control
Each part's speed can be set to run in either direction or to 0 to keep it still, with the rotation direction chosen by sign.
Bounce speed and part skipping
The up-and-down bounce of the crystal has its own speed, and individual parts can be left out of rendering.
Orbit crystals
An orbit tab spawns small crystals that circle the main one, and the amount of orbiting crystals can be changed.

Use cases
Who it’s for: Players who want to change how end crystals look on their own client. Because the mod is client-side only, it suits single-player players and people who join servers without needing the server to run it.
