Randomized Block & Mob Drops
by Dnydd
Randomized Block & Mob Drops shuffles which items come from breaking blocks and killing mobs, including drops from modded content, on a server.
What it does
The mod randomizes the drops of blocks and mobs in Minecraft, covering both vanilla and modded entries. Each world gets its own shuffle, seeded from the world seed, so the same block always yields the same substitute within that world. The mapping is saved with the world and does not change between sessions. Modded blocks, mobs and items are picked up automatically.
The shuffle pool holds only items that already drop naturally in the game, found by scanning loot tables. Nothing becomes unobtainable, because every item in the pool can be gotten through play. Items such as bedrock, barrier, command blocks, structure void, jigsaw, the debug stick, knowledge books and bundles are excluded by default. A warning appears in chat on join when chaos mode is on.
Only the server needs the mod, and players join without installing it. It is published for Forge and NeoForge across 7 release versions, 1.20.1 – 1.21.1, and the latest files are 1.0.4 for 1.20.6 on Forge and 2.0.4 for 1.21.1 on NeoForge. The code is not open source; the project is under All rights reserved and tracks issues in a public issue tracker.
Key features
Block and mob drop shuffling
Drops from blocks and mobs are swapped for other items drawn from the naturally obtainable pool.
Per-world consistency
The randomized mapping is generated from the world seed and saved, so it stays the same across sessions.
Datapack rebuild on change
Changes to the config or mod list are detected on the next world load and the datapack is rebuilt with the same seed.
Lookup commands with tab completion
The rbmdfind and rbmdmob commands suggest matching items and mobs as the user types minecraft.
Blacklist and chaos mode
Entries are removed from the blacklist to return them to the pool, and chaos mode turns off the filters for a fully random result.

What the author says
Every block and mob drop in Minecraft is randomized — vanilla and modded. Just install and play. If you change your config or mod list, RBMD detects the change and rebuilds the datapack using the same seed on the next world load. No manual steps needed.
