EntropyMod
by etie09
With EtiesChallengesMod, survival worlds get a set of toggleable challenges, a timer and randomized drops for solo runs or runs with friends.
What it does
The Fabric mod adds challenge options that change how a survival world plays: a challenge clock, randomized block and mob drops, and a random item handed out on a schedule. Players pick which challenges are active from an in-game menu, and the selected ones stay highlighted so it is always clear what is running. Global mod preferences and a reset option sit in the same menu.
Installation needs Fabric on the loader side, and the environment is server required with client optional, so the server must run the mod while players may add it for the in-game menus. Files target 1.21.5 and 1.21.11, with the latest Fabric build a0.1.155t for 1.21.11, published on the alpha channel on 2026-06-29. The mod was first published on 2025-08-03 and is released under a custom license, so it is not open source.
Key features
Timer controls
A challenge clock can be started, paused, resumed and stopped, and its color is changed in a dedicated menu during play.
Randomized block drops
Each block type drops one completely random item, and the drop stays the same for the whole challenge.
Configurable drop amount
A text field in the challenge menu sets how many items, from 1 to 64, receive the random drop.
Randomized mob drops
Mobs drop random replacement items in the same quantity as their original drops, so a cow that normally drops 2 leather drops 2 random items.
