| “ | 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 |
Magma Core 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, Hot Rock is created when explosions destroy the natural rock of the terrain, where Hot Rock will line the entirety of the border of the explosion. These include even extremely small explosions, such as the ones created by the Thunderhead Autocannon.
Another hazard are Lava Geysers which erupt fire at regular intervals. An imminent eruption announces itself with a rumbling noise. 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. There are also groups of smaller lava geysers or jets which periodically erupt, dealing a minor amount of damage on anyone standing on the erupting jet.
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. What is unique to Magma Core however is that because of how ground broken by explosions create Hot Rock in the area carved by the explosion, each plant explosion will create Hot Rock under the plant, and their chain reactions can create entire fields of intermittently placed Hot Rock.
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.
Biome Features[]
| Item | Description | |
|---|---|---|
| Functional | ||
 Exploding Plant |
Glowing plants of varying size that explode violently when damaged. The larger the plant, the less damage needed to detonate it and the larger the explosion. Also found Dense Biozone and Fungus Bogs. | |
 Lava Geyser |
Rocky geysers which periodically spit out lava upward and burn anyone near it or in direct contact with it. Once destroyed they will explode violently, dealing large amounts of damage to any enemy or dwarf in the vicinity. | |
 Hot Rock |
Hot rock that damages and slightly speeds up anything stepping on it. It can be found naturally in large patches, but also appears from explosive damage made to the terrain. Enemies will attempt to avoid hot rock patches and craters when pathfinding. | |
 Quake |
The cave violently shakes, slowing down the dwarves and creatures movement. It can also create crevices around the dwarves. | |
 Small Lava Geysers |
Groups of small holes in the ground which periodically shoot lava a short distance upwards and deal a small amount of burn damage to anything standing in the jets. | |
| Vegetation | ||
 Yellow Tubel |
Tube shaped plant sucking in particles through the yellow tip. | |
 Chromepuff |
Puffy flowers with chrome coloring. | |
| Rocks | ||
 Mineral Chimney |
Tubular rock formations letting out smoke from their holes. Also found in Crystalline Caverns. | |
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.
