The Deep Caverns is a midgame mining island that helps the player level up their mining skill significantly. The Deep Caverns includes an important section, called the Dwarven Mines, for mid to endgame players.

The Dwarven Mines is a massive cave section under the deep caverns. It consists of new ores, such as Mithril and Titanium. It is an ideal place to level up your mining skill, as mining commissions, which give a lot of XP, help a lot. The Dwarven Mines leads to the Crystal Hallows.

The Crystal Hallows is a massive room with 6 parts. In 5 of the parts, the player must traverse randomly generated cave systems to reach and recieve a Crystal, wich can be placed in the 6th section for items and loot.
It is currently the only section of Skyblock where you can break the entire island. The island resets every 2 hours.
