Luki's Crazy Chambers

by lukidonu

With Luki's Crazy Chambers installed on a server, the Trial Chambers gain redesigned rooms, mobs and loot, and the structures are much larger.

What it does

The mod is a data pack for Minecraft 1.21 that concentrates on the Trial Chambers introduced in that version. Its rooms, mobs and loot tables were rebuilt from scratch, and the chambers now cover more ground, so exploring one takes longer and returns more reward. Because it is a data pack, it changes world generation and loot on the server; players connecting to the server do not need anything installed.

The data pack was made as a one-week challenge, so the number of room layouts is limited for now. The author has said more rooms may be added later if it is well received. The rarity of the Trial Chambers was left as it is in vanilla, so they still generate as often as the original chambers. Loaders listed for the mod are Fabric, Forge, NeoForge and Quilt, and files cover 1.21 – 1.21.11 with 1.0.3+mod for 1.21.11 as the latest build.

Key features

  1. Redesigned chamber rooms

    The Trial Chamber rooms are rebuilt with new layouts, replacing the vanilla room set.

  2. Reworked mobs

    Mobs found inside the chambers are changed, so encounters differ from the original structures.

  3. New loot tables

    Chests and rewards inside the chambers use new loot, giving different items for exploring.

  4. Larger structures

    Trial Chambers are generated bigger than in vanilla, extending the area a player must cross.
