# \ud83c\udfb2 Randomized Block & Mob Drops (RBMD)<\/p>\n
Every block and mob drop in Minecraft is randomized \u2014 vanilla and modded. Just install and play.<\/p>\n
—<\/p>\n
## \ud83d\udcd6 What It Does<\/p>\n
– Every block and mob has its drops shuffled to something completely different
\n– Drops are consistent \u2014 the same block always drops the same thing in your world
\n– Each world gets its own randomization, saved so it never changes between sessions
\n– Works with modded blocks, mobs, and items automatically
\n– Only items that can naturally drop are in the shuffle pool \u2014 nothing becomes unobtainable
\n– If you add, remove, or update a mod, the datapack rebuilds automatically on next world load<\/p>\n
—<\/p>\n
## \u2699\ufe0f How It Works<\/p>\n
Load a world. RBMD automatically:<\/p>\n
1. Scans all loot tables to find every naturally obtainable item
\n2. Shuffles them using your world seed
\n3. Writes a datapack and reloads \u2014 drops are active immediately<\/p>\n
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.<\/p>\n
> \ud83d\udd01 Want completely new drops? Run `\/rbmdreshuffle` at any time.<\/p>\n

## \ud83d\udcdc Commands<\/p>\n
| Command | Description | Both `\/rbmdfind` and `\/rbmdmob` support **tab completion** \u2014 start typing `minecraft:` or `mymod:` and it will suggest matching items and mobs.<\/p>\n **Debug commands (OP only)**<\/p>\n | Command | Description | > \ud83d\udca1 Use `\/rbmddump` to review all changes and copy IDs straight into the blacklist config.<\/p>\n —<\/p>\n ## \u2699\ufe0f Config<\/p>\n File: `config\/rbmd-common.toml`<\/p>\n Changes are detected automatically on next world load \u2014 no need to run `\/rbmdreshuffle` unless you want new drops entirely.<\/p>\n | Option | Default | Description | **Item blacklist defaults** \u2014 excluded because they can’t be obtained naturally: `bedrock`, `barrier`, `command_block`, `chain_command_block`, `repeating_command_block`, `structure_block`, `structure_void`, `jigsaw`, `light`, `debug_stick`, `knowledge_book`, `bundle`. Remove any entry to put it back in the pool.<\/p>\n **Blacklist format** \u2014 use full registry IDs: ### \ud83d\udd34 Chaos Mode<\/p>\n Setting `chaos_mode = true` skips everything \u2014 blacklists, spawn egg filter, and the natural drop filter. Every registered item enters the pool. A warning appears in chat when you join with chaos mode on.<\/p>\n > \u26a0\ufe0f Some items may become unobtainable in chaos mode. Use at your own risk.<\/p>\n —<\/p>\n ## \ud83d\udd27 Notes<\/p>\n – **Wrong tool = no drop** \u2014 same as vanilla. A block that needs a pickaxe drops nothing without one. This mod randomizes all block and mob drops in Minecraft \u2014 including modded ones.<\/p>\n","protected":false},"featured_media":129415,"template":"","meta":{"_minecraft_slug":"rbmd","_minecraft_project_id":"gTOR8pvl","_minecraft_author":"DKLYNTLY","_minecraft_license":"LicenseRef-All-Rights-Reserved","_minecraft_downloads":322,"_minecraft_follows":1,"_minecraft_client_side":"unsupported","_minecraft_server_side":"required","_minecraft_storage_type":"zip","_minecraft_archive_name":"rbmd.zip","_minecraft_size_bytes":113328,"_minecraft_version_count":5,"_minecraft_updated_at":"2026-05-15T17:08:24.249794Z","_minecraft_date_created":"2026-03-25T03:30:20.388320Z","_minecraft_date_modified":"2026-03-22T18:54:23.301028Z","_minecraft_project_url":"https:\/\/modrinth.com\/mod\/rbmd","_minecraft_icon_attachment_id":129415,"_minecraft_imported_at":"2026-06-07T14:55:40+00:00","_minecraft_import_hash":"c2fa3682b8088b997a0ac0197ab4769a","_minecraft_versions":"","_minecraft_links":"","_minecraft_gallery":"","_minecraft_api_metadata":""},"mod_category":[87,89,137,158,159],"mod_loader":[160],"minecraft_version":[37],"class_list":["post-129414","mod","type-mod","status-publish","has-post-thumbnail","hentry","mod_category-adventure","mod_category-game-mechanics","mod_category-mobs","mod_category-neoforge","mod_category-worldgen","mod_loader-neoforge","minecraft_version-1-21-1"],"yoast_head":"\n

\n– **Same seed = same drops** \u2014 two worlds sharing a seed will have identical randomization. Use `\/rbmdreshuffle` to override.
\n– **Each world is independent** \u2014 worlds store their own seed and config hash in `datapacks\/rbmd_randomizer\/`. Switching between worlds never affects each other.
\n– **Adding or removing mods** \u2014 detected automatically. Drops will shift slightly since the pool size changes, but the same seed is reused so existing items stay as consistent as possible.
\n– **Silk Touch** \u2014 randomized by default. Set `randomize_silk_touch = false` if you want Silk Touch to always give the original block.
\n– **Mods with hardcoded drops** \u2014 mobs that skip the loot table system are still covered by an event hook on every mob death.
\n– **Debugging** \u2014 all output tagged `[RBMD]` in `latest.log`. Use `\/rbmddump` to export a full human-readable list of every drop change.<\/p>\n","protected":false},"excerpt":{"rendered":"
