Random Effects
Every Chunk has a random Effect signed to it. Every time you close and reenter the world the effects will be randomized again. This could later be changed in newer versions, but for now it's a hardcoded feature, to make it not too easy.
Effect Modes
You can choose the Timer Mode or the Chunk Mode. Open the UI simply by pressing K. Chunk Mode: Every chunk has its own effect, so every chunk you enter could give you a good or bad effect with a random value, so everything from Haste 5 to Weakness 6 is possible.
Timer Mode: You can select a timer and every 5 minutes for example you will get a new random effect that has its own duration. So you can select every 1 minute a new effect, and can get speed for 10 seconds or 55 seconds and when 60 seconds are over, you will automatically get a new random effect.
