The Ironclad prefers to attack targets who are not marked in this way.
Appearance Ironclad are constructs of metal and fire. They are comprised of two legs, two arms, two shoulders and a torso with a diminutive, double-horned head nestled on top. It's body is a dull silver and onyx and various sigils, of unknown origin, are etched into it in a uniform fashion. Most predominately, a large one on it's chest. It's structure moves loosely but freely, in a vaguely humanoid form, with a singular floating orange ring connecting each body part together. Fire erupts upward out of the gaps the rings occupy and out of the top of it's head, continuously. The hands and feet are crude, three-pronged claws. The right claw usually carries a large, blunt instrument, a wide greatsword or great club, the same coloration as it's body.
Tactics Ironclad tend to lie dormant in scrap heaps until they detect movement. Although they are slow, they chase relentlessly. Even if they pursue their quarry to an empty hollow into which they cannot reach, they will simply stand at the opening until they can no longer detect movement. If their target manages to evade detection or is slain, the Ironclad slowly returns to its resting place unless another humanoid crosses its path. Despite its low intelligence, it appears to have an analytical fighting style, choosing attacks that maximize the number of combatants that it can hit (Although, it seems to disregard creatures struck by it's Ballistic Kick action or sometimes it's Arm Cannon action). After the defeat of its body, its head can sometimes switch into a state of hibernation and attempt to play dead or immediately rocket out of the torso and back to its haunt to attempt to forge a new body. The body cannot function without its head. Should the head of the Ironclad be cornered or is found out as it attempts to play dead, it will usually choose to become aggressive.

Lore Ironclad are otherworldly constructs from a ruined dimension where ragtag bands of refugees stranded in the harsh borderlands struggle for their survival against ungodly fiends and the wrath of the land itself, the land of Abyssea. These constructs tend to lie close to the burning wreckage of airships or large armoured vehicles. The keen observer would note that over the course of a week or two, the Observer Unit (head) of this creature can be seen amongst the scrap, carefully twisting together metal limbs and fashioning a chassis for itself with some kind of telekinetic force. While, at first, refugees took the inhospitable environment and lack of fauna as a sign of safe travels through the site of a downed airship, it is these wretched automaton that met the hapless survivors. Although, no one knows their true origin, one popular theory suggests that a will-meaning but misguided Puppetmaster or Artificer, intending to turn the loss of the airship fleet into an asset, created these self perpetuating weapons.
