An Infernal armour is a monster first featured in Dragon Quest III: The Seeds of Salvation. Like the restless armour, it is a mass of moving metal that has taken up its sword against humans, but if much more dangerous than its wandering counterpart. Formerly depicted as staunch lone wolves, they have learned to summon allies in battle like their contemporaries as of the eighth game.
Ambulatory suits of cursed armour. Beware their swords. When driven into the ground, they can stun a group of adversaries with powerful lightning bolts.
Empty suits of armour possessed by the souls of soldiers, and fated to fight till their deaths are avenged. The armour itself was forged in an infernal furnace—rumour has it that they mass produce them in purgatory.
