“Unleash the terror of the Iron Colossus: a colossal war machine that breathes deadly fumes and crushes foes with unstoppable might!”
The Iron Colossus is a towering behemoth, standing at an imposing 80 feet tall and weighing around 500 tons. Its exterior is a patchwork of reinforced iron plates, each one riveted and welded together, giving it a rugged, industrial appearance. The surface is often scarred from countless battles, with patches of rust accentuating its massive form. Its limbs are thick and muscular, designed for both crushing blows and precise maneuvers. At the center of its body, a massive grinding engine emits swirling plumes of noxious fumes, obscuring its silhouette and adding an eerie glow from the glowing embers of its fiery core. Two heavy ballistae are mounted on its shoulders, each capable of launching deadly projectiles with precision. The Iron Colossus’s eyes glow ominously, often reflecting the fiery hues of its internal machinery, and its formidable flail, capable of sweeping away foes, hangs menacingly from one arm.
Behavior
The Iron Colossus is a relentless and single-minded construct, programmed for destruction. It exhibits a mechanical intelligence, responding to threats and commands with cold efficiency. When activated, it moves with a surprising grace for its size, stomping through enemy lines with calculated aggression. The colossus shows no mercy, crushing anything in its path, and its behavior is often driven by the tactical orders of its creator or operator. While it can act independently, it is typically employed as a siege engine, using its overwhelming force to breach fortifications and create chaos among enemy ranks. The iron giant emits a low, rumbling sound as it moves, the grinding of metal on metal echoing like distant thunder.
Habitat
The Iron Colossus can be found in any war-torn landscape, typically deployed in areas of conflict such as besieged cities, battlefields, or near enemy fortifications. It often resides in a temporary encampment alongside other siege engines and war constructs, where it is maintained and repaired by its creators. These constructs are often crafted in specialized forges or workshops dedicated to the art of war machine engineering. While it does not have a natural habitat, the Iron Colossus thrives in environments where it can exert its dominance, often surrounded by the remnants of destruction.
Modus Operandi
The primary modus operandi of the Iron Colossus is to serve as a front-line assault machine. Upon entering a battlefield, it releases a deadly cloud of toxic fumes that disorients and weakens foes. It uses its incredible strength to crush enemy soldiers and structures alike, favoring powerful melee attacks with its flail and devastating stomps. The mounted ballistae allow it to engage targets at a distance, raining down projectiles on any threats that dare approach. The colossus’s ability to transform its legs into a trample attack mode enables it to steamroll over groups of enemies, causing massive devastation. Its selective antimagic aura provides a strategic advantage, neutralizing spells that might threaten its operations.
Motivation
The Iron Colossus is driven by the singular purpose of warfare and destruction. As a construct, it lacks personal desires or emotions, operating solely on the commands given by its creator or operator. Its primary motivation is to serve as a tool of war, designed to crush opposition and create a path for victory. In a broader sense, the Iron Colossus symbolizes the unyielding advance of industrial warfare, a testament to the power of engineering in the service of conquest. Its presence on the battlefield serves to intimidate enemies and bolster the morale of allied forces, embodying the relentless march of war machines in an age of conflict.

- On a successful save, the creature takes half damage and is not poisoned.
- A poisoned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Trample (Recharge 6)
- If the Iron Colossus moves at least 30 feet in a straight line and then hits a Medium or smaller creature with a Stomp attack, that creature must succeed on a DC 25 Strength saving throw or take an additional 84 (24d6) bludgeoning damage and be knocked prone.
Siege Artillery
- The Iron Colossus can fire its Ballista as a ranged weapon.
- Ranged Weapon Attack: +18 to hit, range 120 ft./480 ft., one target.

Regional Effects
The presence of an Iron Colossus in the region creates the following effects:
- War-torn Landscape: The area around the Iron Colossus is marked by destruction. Terrain may be difficult due to craters, collapsed structures, and areas of poisonous gas lingering in the air.
- Construct Minions: Inhabitants within a 5-mile radius may witness the emergence of lesser constructs, such as Iron Golems or Stone Sentinels, drawn to the colossus’ power.
- Firestorms: Areas within 1 mile of the Iron Colossus are prone to sudden bursts of flame, causing fire damage to creatures caught in the area. Creatures that start their turn within 30 feet of the colossus take 10 (3d6) fire damage.
Lore
The Iron Colossus stands as a testament to the formidable power of ancient engineering, a relic from a time when powerful mages and skilled artisans combined their knowledge to create a war machine unlike any other. Crafted from countless tons of enchanted iron and powered by the very essence of fire, these towering constructs were originally designed as siege weapons to breach the fortifications of enemy kingdoms.
Unique Traits
- Strengths:
- Massive Damage Output: Capable of inflicting devastating damage with each attack.
- Area Control: Its Deadly Fumes and Trample abilities create hazardous zones that hinder movement and pose a constant threat to adventurers.
- Weaknesses:
- Slow Movement: Despite its speed, its colossal size can make it vulnerable to ranged attacks if it is not careful.
- Limited Intelligence: Lacking strategic thinking, it may become predictable in its attacks.
Role in a Campaign
The Iron Colossus can serve as a major antagonist in a campaign, perhaps a guardian of a powerful artifact or a tool of a warlord seeking to conquer a kingdom. Its presence may trigger a quest for the players to either find a way to disable it, destroy it, or perhaps control it for their own purposes.
Conclusion
The Iron Colossus is not merely a mechanical giant; it is a force of nature, an embodiment of destruction, and a pivotal point in any campaign. Encountering this colossal construct will test the limits of any adventuring party, ensuring a memorable battle filled with strategy, fear, and epic heroism!
A siege engineer’s nightmare, this giant machine emits noxious fumes from its grinding engine. These are mainly made by either Hephaestos or his servants.
