Melee Attack: +7 to hit, reach 10 ft., one target. Hit: 20 (3d8 + 3) piercing damage.

Magnetic Wave

Monster Description

The Magnetron is a bizarre construct shaped from a liquid metal alloy that coils and shifts like mercury. Glimmering under the light, its form is an ever-changing mass of smooth metallic surface, reflecting its surroundings with shimmering hues. Standing large and imposing, it can change its shape seamlessly, adapting to fit any environment, even squeezing through narrow openings, making it a master of stealth and surprise. Its ability to manipulate magnetic forces allows it to attract and repel metal objects at will, making it a formidable opponent.

Monster behavior

The Magnetron is instinctively drawn to technological sites, constantly seeking to absorb resources to sustain itself. In battle, it prefers to surprise its foes with its shape-shifting capabilities, intimidating with spikes formed from its own body while utilizing its magnetic wave to disrupt the formation of enemy ranks. Known for its cunning tactics, it often retreats to regroup or alter its tactics if it senses it may be overwhelmed or harmed significantly. It can divide itself into smaller versions to confuse enemies, turning a single foe into multiple targets.

Ecology

Within the ecosystem, the Magnetron serves as both a scavenger and a destroyer, feeding on remnants of technology and machinery. It plays a vital role in recycling metal materials and can often be found around abandoned or decaying technological sites such as factories or research labs. This construct is chiefly responsible for ensuring that no significant source of technology is left unused, contributing to an ongoing cycle of destruction and renewal in its domain.

History

The Magnetron was first discovered in the ruins of a long-lost civilization, thought to have been highly technologically advanced. Legends tell of a race of metal-shaping beings that manipulated magnetic fields to create living constructs. Over centuries, as the civilization collapsed and technology fell into disrepair, these constructs became solitary wanderers in search of purpose. Some believe they are guardians of forgotten secrets of technology and magic. Today, they can be found in various desolate areas where technology and nature collide, embodying both the majesty and the dangers of a potent merging of forces that many would like to harness for their own purposes.
