Crystal

Difficulty: Class 1
The Crystal level is the third level of the of the underground. It is the second layer to contain new ores (the Maze level is the first).

The terrain here is composed of caves and ravines of similar sizes and densities to those in the Overworld. However, the caves are equally large and frequent at all depths, resulting in caves extending longer than normal and intersecting with other caves more often, creating a maze-like structure it is easy to get lost in.

The ores in this level include the default vanilla ores, as well as the crystals: Aquamarine Ore, Ametrine Ore, and Sapphire Ore.
