Random Mob Challenge (RMC)
Ready to turn your world into a chaotic survival test? Random Mob Challenge is a lightweight but intense mod that ensures danger is always just a few ticks away.
The premise is simple: a random mob spawns near the player at a set interval. It could be a harmless sheep, or it could be a Ender Dragon.
🛠️ The mod is fully controllable via two simple in-game commands:_
/rmc enable-disable: Toggles the mod on or off. Use this when you need a break or if things get too crowded. With this Command, you also need to Start the Challenge.
/rmc interval <ticks>: Sets the time between spawns. Remember that Minecraft runs at 20 ticks per second. Setting the interval to 400 means a new mob every 20 seconds, while setting it to 20 means a new mob every single second.
Whether you are looking for a new way to play hardcore or just want to spice up your next livestream, RMC provides a layer of unpredictability to your gameplay.
