The science areas are made for adventure: explore, face challenges, get loot and grow stronger over time!
There's an increasing difficulty order to the main challenge areas; it is recommended to visit them in order to learn how they work and build up your equipment.
In order to aid in ensuring you get the most out of your Science explorations, the Collectibles system was introduced. For full information, visit the news post.
You can visit the Cavern of Science, under the Creeper Citadel, to see the full list of items that can be obtained. Bring a shulker box filled with sheets of paper to the cavern, tap the box against one of the chests, and obtain a blank copy of its content! You can then bring that back home, replace the named sheets of paper with your actual items, and view your current progress. It's like filling a collectibles album, one item at a time!
There are various bonus areas in each of the previous locations.
