Crazy Chambers
by ESMP
Crazy Chambers changes the trial chambers of the world generator, with larger chambers, a built-in loot editor and fixes to features that behaved unexpectedly.
What it does
The mod enlarges trial chambers during world generation, so each one holds more space to explore. Its built-in loot editor lets server owners tune the contents of chests, barrels, pots and vaults without editing data packs by hand. Several features that did not work as intended have been fixed and improved in this release.
The server must run the mod, while players may leave it out and still join. It is published for Fabric, Forge, NeoForge and Quilt, and a data pack build is available for servers that prefer that route. Files cover game versions 26.1 – 26.3, and the 1.3.0 file for 26.3 is the latest release. Crazy Chambers is released under All rights reserved, though its source code and issue tracker are publicly linked. Its data pack and mod versions are repackaged together, so one copy works on each loader and on every release in the range.
