Deep Rock Galactic Wiki

Among the most spectacular sights on Hoxxes,, the aptly-named Crystalline Caverns are truly a sight to behold. Massive crystals erupt from every surface, glittering and twinkling in the dark. Alas, the larger crystals are mostly worthless silicate, but abundant deposits of valuable minerals dot the caves too.
— Ingame description

Crystalline Caverns is one of the biomes of Hoxxes IV. This eponymous biome consists of caverns filled with many (although worthless) crystals.There are many big, open chambers, connected by tunnels. The crystals produce natural light, allowing more visibility for navigation. The base rock making up the caves is sturdy, taking 3 hits for it to give way.


The biome-specific hazard for Crystalline Caverns is the bright and noisy Electrocrystal, which is charged with electricity. Dwarves or Creatures that come into direct contact suffer high damage and slowdown. If multiple Electrocrystals are close together and have unbroken line-of-sight with other Electrocrystals, electricty will arc in a curved shape between the crystals, causing high damage and slowdown to Dwarves or Glyphids passing through the arc. The Electrocrystals cannot float, so destroying the surrounding bedrock can destroy them.

There is a 15% chance to rain in Length 1 missions, increasing by 3% for every Length. Rain reduces the brightness of flares and other light sources, and dwarves all gain a 100% resistance to all forms of Fire and Heat damage, such as Gas explosions and the Driller's Flamethrower. It does not increase the rate at which Freezing can be applied, however.


Most Glyphids can be encountered in Crystalline Caverns, including Spitball Infectors, Cave Leeches, and Glyphid Dreadnoughts.

Biome Features[]

Crystalline Caverns feature little to no vegetation, as the biome is entirely made out of rock material.

As with every biome, some of the Ores that can be found in Crystalline Caverns are determined by the mission type, such as Morkite Morkite and Aquarq Aquarq. The crafting materials found in Crystalline Caverns are Jadiz Jadiz and Bismor Bismor, with Bismor being abundant and Jadiz being scarce.
