Ultimate Randomizer Multiplier
by snorlaxmax23
Ultimate Randomizer Multiplier changes what breaking blocks and killing mobs produce, replacing normal loot with randomized results on Fabric.
What it does
The mod completely randomizes drops. A block broken or a mob killed no longer gives its usual loot; instead each source is assigned a random result that stays fixed. Each assignment can be a random item drop, a random mob spawn, or a random quantity, and in the chaos variant half the assignments drop items while the other half spawn mobs, so breaking dirt can summon a creature. The mod can also multiply drops.
Assignments are saved with the world and stay consistent until a player decides to reset them. A tool requirement is either removed or set so that every block drops something regardless of which tool it is broken with. Killing a Warden can yield a single potato, which shows how far the results can differ from vanilla loot tables.
Installation needs Fabric API. The mod is for Fabric only, runs on client and server, and covers 8 release versions, 1.21.4 – 1.21.11. It is released under All rights reserved and is not open source.
Key features
Random drop assignments
Each block and mob source receives a random drop result that replaces its vanilla loot table.
Chaos drop mode
Results can mix item drops with mob spawns and random quantities, so a broken block may summon a creature.
Drop multiplication
Drops can be multiplied in addition to being randomized, increasing the number of items a source returns.
Saved, consistent results
Assignments are stored in the world and remain the same until reset, so the randomization does not change between sessions.
Tool requirement changes
Blocks can drop something regardless of the tool used, removing the need for specific tools to collect them.

Use cases
Who it’s for: Players and server owners who want randomized, unpredictable drops in a Fabric world. The mod needs to be installed on both client and server, with Fabric API present on each side.
How it compares
Size Randomizer is a Fabric mod for 1.21.1 – 1.21.11 that is also client and server, but it is not open source. Portal Randomizer is server-side only, released under the CC0 1.0 Universal license and open source, but it targets 1.21.8 alone. DropMultiplier only covers 1.21.11 and does not randomize assignments.

What the author says
Chaos Drop completely randomizes every drop in the game — breaking blocks and killing mobs no longer gives their normal loot. Instead, each source is permanently assigned a random result: either a random item drop or a random mob spawn, in a random quantity. Half of all assignments drop items, the other half spawn…
