Randinium
by torchy
Randinium changes the drops of blocks and mobs, so ordinary breaking and killing can yield rare custom items on a Fabric game for 1.21.8.
What it does
The mod makes drops random. Blocks and mobs both release random items, and blocks drop their own items except where the mod makes an exception. Leaves can drop saplings through decay. Across all of this the mod is meant to reach more than 1600 possible items, including some that a player would normally not obtain in survival.
A new custom drop called Randinium is about three times rarer than other items. Tools made from it can multiply random drops up to four times, and looting and fortune enchantments still change how many items come out. Stable Randinium Tools form an endgame toolset that prevents random drops. Crafting a Stable Randinium Ingot takes three Randinium Ingots and six gold ingots in the crafting grid, and a Stable Randinium Rod is made from one stable ingot placed among four Randinium Rods with a sign. The mod is intended for Skyblock maps.
Randinium is a Fabric mod for 1.21.8 only. It is released under All rights reserved, so it is not open source. Both the server and every player need it, and the latest Fabric file is 1.0.0, published 2026-06-21.
