Extreme Skyblock is everything from the original and more! It has lots of islands, one for each biome, and each dimension. In this map, your goal is to complete all of the challenges that you can find at spawn, and obtain all of the types of resources. Try to conquer the islands, and make them your own, or have a base on each one. The choice is up to you!
You can even trade on some of the islands. Custom villagers have special trades that you can unlock, and offer a lot of items.
