⬇ Download on ModrinthChaos Randomizer is a Fabric 1.21.1 mod that turns every Minecraft session into a randomizer full of chaos and objectives.
WARNING : Multiplayer for the mod is not supported yet. It's currently not really playable, even if you try. However, it will be added in the future with both Versus and Co-op modes.
How it works
Pick the number of challenges and a time limit. A roulette animation reveals your objectives — then the chaos begins. You must complete all your challenges before the timer expires, then defeat the Ender Dragon to win.
Random events fire every few seconds: teleportation, random items, potion effects, mob spawns, lightning, time and weather changes, and more.
Features
- 40+ challenge types — kill mobs, mine blocks, reach XP levels, wear full armor sets, get rare items, sleep nights, and more
- Chaos events every configurable interval (default: every 10 seconds)
- Countdown timer with a game over screen when time expires
- Speedrun timer to track your best runs — saved through crashes and reconnections
- Roulette animation when challenges are assigned
- Re-roll system (up to 3 times) before starting
- Custom music — drop
.oggfiles inconfig/chaos_randomizer/music/and they play as background music - Bilingual — English and French, auto-detected from your Minecraft language setting
