Mirror World adds a separate dimension with vanilla Overworld terrain, biomes, ores, and structures, giving you another world to explore and gather materials in.
Craft a Mirror Stone, right-click, and stand still for four seconds to travel between the Overworld and Mirror World.
The Mirror Stone remembers your last departure position in each dimension, so you can return to your mining spot or continue exploring where you left off. Your saved positions persist across restarts and work with replacement stones.
Mirror World shares your save’s world-generation seed, but its terrain and changes are stored separately. It does not automatically reset.
