Random Mob
by NikkiSh
Random Mob is a NeoForge minigame for 1.21.1 in which a new mob with a random modifier spawns every 30 seconds, turning survival into a timed challenge.
What it does
Players start a vanilla survival world, and the mob spawns repeat on a timer. Each spawned mob carries one modifier chosen at random from 81 possibilities, which can make a fight far harder. The goal is to beat Minecraft by defeating the Ender Dragon before the chaos wins. Installation needs NeoForge for 1.21.1, and the environment is client and server, so the server and every player need the mod. It is released under All rights reserved and is not open source.
Key features
Timed mob spawns

81 random modifiers
