💡 Pro Tips & Customization
- Use /rc exclude add minecraft:... to prevent a chunk from turning into a lag-fest.
- Chunk Walker Boots: They protect you from all world-randomization and effects, but they lose 10 durability per chunk.
- Status effects/curses are disabled by default. Enable or disable them using
/rc effects. Active chunk effects are removed immediately when you leave the chunk, use Chunk Walker Boots, stop the challenge, or disable effects.
