Extreme Randomizer

Extreme Randomisor shuffles what Minecraft gives you. Break a stone block and get a trident, kill a zombie and get copper grates, open a dungeon chest full of things that have no business being there.

Comes as a datapack, a Fabric mod and a Paper plugin. Pick one, they do the same job.

What gets randomised

Area · Datapack / Fabric · Paper plugin
Block drops · yes · yes
Mob drops (incl. shearing, charged creeper heads) · yes · yes
Chest loot (dungeons, strongholds, villages, trial chambers, vaults) · yes · yes
Fishing · yes · yes
Archaeology, sniffer, piglin bartering, hero of the village and cat gifts · yes · no
Crafting results (crafting table, crafter, recipe book) · no · yes
Smelting (furnace, blast furnace, smoker, campfire) · no · yes

No setup needed

The seed is rolled automatically the first time a world loads with the randomiser. There is nothing to generate and no script to run.

Datapack and Fabric: a clickable settings menu shows up in chat on load, or open it with /function extreme_randomisor:settings. From there you can roll a new seed, type your own (0 to 1023), switch modes and turn each area on or off. Changes apply instantly.

Paper: everything goes through /randomizer (alias /rnd), permission extremerandomisor.admin:

/rnd status
/rnd seed
/rnd mode
/rnd toggle
/rnd guaranteed
/rnd reload

Two modes

Consistent: every block, mob and chest type has its own fixed random item. Same seed, same world. This is the classic randomiser run.

Chaos: every single drop is rolled again.

Things it does not break

• Vanilla rules stay: doors and beds drop once, glass still needs silk touch, fortune and looting still raise the amount.
• Shulker boxes and bee nests keep their contents.
• Donkey chests, picked-up gear and named or enchanted items are never replaced.
• Furnaces keep working with hoppers, because the plugin rewrites the recipes instead of swapping the output.

Versions

• Minecraft 26.2 and 26.3. One datapack covers both.
• Fabric needs the Fabric API. There is a separate jar for 26.2 and for 26.3.
• Paper plugin: Paper 26.2 or newer, Java 25.
