Random effect
Random effect is a chaotic and exciting Minecraft mod where the goal is simple — survive.
Random status effects hit you at configurable intervals, and not all of them are friendly.
Some will help. Others will definitely try to kill you. It’s the ultimate test of luck, skill, and endurance.
Whether you play solo, with friends, or on stream — this mod brings unpredictable fun to your world.
