Just how summary says: Earn advancements to expand your world. There was no simmilar mod for Forge 1.20.1, and so I made one.
You start as usual, except you are confined by 100x100 block world border. Complete advancements, goals and challenges to expand your world. Completing regular advancemets (tasks) expands the borders by 10 blocks, goals - 50 blocks, challenges - 100 blocks. Rewards and start borders are configurable.
It works in multiplayer and should be compatible with any modded advancements. I highly recommend playing it with a large modpack with hundreds of achievements for the best experience. ENJOY!
BEWARE: if you run this mod in your already existing world, you might end up outside the world border and die. So check the config before doing something like this.
