Crazy Chambers: Bigger Trial Chambers Data Pack
DATAPACKA data pack overhaul that turns trial chambers into huge, unique layouts filled with trial spawners and vaults—no two chambers alike.
Crazy Chambers reworks the generation of trial chambers so every instance is significantly larger and far less predictable. Instead of the vanilla game's handful of pre-designed rooms that repeat in every chamber, you get sprawling, multi-room dungeons with complex hallways, vertical drops, and dense clusters of trial spawners and vaults. This directly solves the problem of chamber fatigue—where after one or two chambers you've seen everything the structure has to offer.
This pack is ideal for any player who wants more engaging exploration and longer combat sequences. Server administrators and map makers will get extra mileage from it when combined with chunk protection and automatic reset tools, because the high spawner and vault density turns each chamber into a renewable loot farm that can be cleared, protected, and reset for dozens of players. Solo adventurers benefit from genuinely fresh layouts on every expedition.
This is a community-updated re-release of lukidonu's original “Crazy Chambers” project, which was discontinued. I've updated it to work with current Minecraft releases, corrected features that were misbehaving, and repackaged the content as a vanilla data pack (plus an optional mod version for major loaders). All original design credit goes to lukidonu.
- Generates chambers that are up to three times larger than vanilla, with many more branching paths and rooms.
- Replaces the repetitive oval room loop with varied shapes, multi-level floors, and connecting corridors unique to each generation.
- Increases trial spawner and vault counts dramatically, so combat is sustained and rewards are worth the risk.
- Integrates with third-party snapshot and reset tools for multiplayer dungeon farming without manual rebuilds.
- Functions as a zero-dependency data pack; optional Fabric/Forge/NeoForge/Quilt mod package also provided.
Requires Minecraft 1.21 or later. No additional files or mods are necessary for the data pack. Simply install in the datapacks folder of your world.
