Bite. The bite of an arctic worm deals normal damage to TL 3 vehicles, and minimum damage to TL 4 vehicles.
Melt Metal. The metabolism of the arctic worm produces high heat all around the creature. The heat can melt metal and metal alloys in an average range of 10 meters. Soft metals like lead, gold, or aluminum melt in 1d4 rounds. Hard metals like iron or iron-based alloys melt in 10 minutes. This ability can be activated once per scene. The heat generated around the arctic worm cause 1d4 cumulative heat damage per
round for 1 minute. The heat damage is cumulative only if the Arctic Worm does not move from its position.
Swallow. The arctic worm swallows a target if it scores a hit roll 5 points higher than the minimum required. Once the target is inside the worm, it automatically suffers 1d4 cumulative heat damage per round until killed or expelled.
COMBAT & TACTICS
Arctic worm’s main attacks are its bite and its heat. They do not attack living beings unless threatened but they perceive electronic components as a potential meal especially if this stuff contains rare metals. Arctic worms prefer to ambush their targets other than carrying direct attacks. They usually melt the ice under any potential target and then fight with bites and heat waves to finish it off.
DESCRIPTION
Arctic Worms are 6 to 12 meters long worm-like creatures covered by a chitinous plating composed of highly conductive metals. They vary in color from a deep blue to a shallow green, with some specimens turning white in advanced adulthood. They have a pair of hooked limbs for each meter of length, which they use to climb on difficult terrains. The head has one or multiple sets of eyes, depending on the
evolutionary strain and the local planetary circumstances.
HABITAT
Arctic Worms evolve in cold and icy planets, usually with high gravity and high atmospheric pressure. They prefer to make their lairs in subterranean caves located under the ice plateau and thanks to their ability to produce heat they do not need to dig, but they simply melt the ice and let them sink to the desired depth. They are excellent climbers, even if not very quick.
BIOLOGY
Despite their fearsome appearance, arctic worms are not predators. They feed on melted ice with an extremely high concentration of minerals and salts. The ice can be water ice, ammonia ice, or other icy compounds, within the planet’s environment. Arctic worms are the object of savage hunts by bands of gatherers that want to extract rare metals from their chitinous plates. A single specimen of arctic worms can yield 1d4 x 100 credits of rare metals per hit die. If a band of hunters ever wants to hunt these creatures, they would better equip themselves with proper vehicles and weapons.
