Minecraft challenge
Biome = Effect
One step into the next biome can change everything. Each biome has a fixed effect randomly assigned for your run.
- Java & Bedrock
- Private server
- No extra mods
Your surroundings matter
Each biome has its own effect
Each biome gets a random effect for your run. It stays the same. When you enter a biome, the game shows its effect. Some help you, others harm you.
While you stay in the biome, lasting effects keep refreshing. An instant effect only happens once when you enter. Remember which biomes help you.
The assignment stays stable during the run and is discovered together.
Example round: you get a helpful effect in a forest. Your team remembers the spot. At the next biome, one of you goes in first and tells the others which effect it has.

What to expect from your run
- Rule complexity
- The same biome always gives you the same effect during this run.
