Magma Core

"Among the deepest of our mining sites, the Magma Caves are a mellow 250-400 degrees and helpfully lit by the churning, molten innards of the planet. We advise that you do not touch anything not mandated by the mission objectives, as your employee insurance does not cover burns."

- Ingame description

is one of the biomes of Hoxxes IV. It features many hazards relating to fire and/or magma. The rock forming the caves is sturdy, taking 3 hits to destroy. Many of the caves feature large rooms with 2 layer plateaus and large circular indents in the surrounding terrain.

Hazards
The most common and prominent hazard in Magma Core is the Hot Rock, which can cover much of the floors of caverns. When stepped on, it will cause burning damage periodically. Additionally, more Hot Rock is created when explosions destroy the natural rock of the terrain, leaving more hazardous floor in their wake.

Another hazard are Lava Geysers which erupt fire at regular intervals. Destroying the center of a Lava Geyser will instantly cause an explosion dealing a massive amount of damage, leaving a crater where the geyser used to be. An imminent eruption announces itself with a rumbling noise. There are also groups of small lava geysers or jets, which deal a minor amount of damage while standing in the lava jet, which activates periodically.

Occasionally, the entire cave shakes violently in a quake, dramatically slowing all dwarves and creatures movement speed to a crawl. The quake may crack the ground open, exposing large crevices of Magma Rock.

Magma Core also has Explosive Plants, which explode violently when sufficiently damaged. These explosions are able to trigger other nearby plants, which can then cause a deadly chain-reaction. These however are not entirely unique to Magma Core, as the same or similar explosive plants are located in other biomes.

Quake
Quakes makes Dwarves x0.5 slower, and creatures x0.75 slower. The start (in seconds) of the first Quake of a mission is decided by squaring a value between 3 and 60, with later Quakes having a delay of 2 - 6 minutes.

Enemies
Most Glyphids can be encountered in Magma Core, including Spitball Infectors, Cave Leeches, and Glyphid Dreadnoughts.

Ores
As with every biome, some of the Ores that can be found in Magma Core are determined by the mission type, such as Morkite and Aquarq. The crafting materials found in Magma Core are Magnite and  Croppa, with Magnite being abundant and Croppa being scarce.
