Hierrmagon, the Four-Armed Forge Tyrants of Avernus
The Hierrmagon is a towering four-armed devil-smith of Avernus, a master armorer of the Blood War who forges enchanted weapons from damned souls and wields four warhammers in a relentless, furnace-lit storm of iron and flame. Equal parts artisan and executioner, it empowers infernal legions with hell-tempered steel and crushes intruders beneath a rhythm of perfectly measured destruction.
Appearance
A hierrmagon stands over nine feet tall, its massive frame sheathed in bronze-hued, heat-scorched flesh that gleams like forged metal. Four heavily muscled arms sprout from its broad torso, each capable of wielding a full-sized warhammer with terrifying precision. A pair of backward-curving horns crowns its furnace-hot brow, while a thick, scaled tail drags behind it, scoring sparks across stone floors.
Its mouth gapes wide with jagged, iron-hard fangs, exhaling sulfurous smoke with every breath. When enraged, magma-like light flickers from its nostrils and between the seams of its plated skin, as though a forge burns within its chest.
Behaviour
Hierrmagons are methodical, disciplined, and obsessively industrious. They move with deliberate efficiency, whether hammering at an anvil or crushing a foe’s ribcage. Speech is curt and transactional, delivered in a low, grinding cadence like stone dragged over steel.
They prefer structure and hierarchy, rarely acting without purpose. Even in combat, their strikes fall in measured rhythm — as if the battlefield were merely another workshop.
Habitat
Hierrmagons dwell in the infernal foundries of Avernus, within vast basalt forges lit by rivers of molten iron and chained soul-furnaces. These industrial hellscapes resound with hammer-blows, clanking chains, and the screams of spirits bound into weaponry.
They are almost never encountered far from their forges unless summoned, assigned to a war effort, or overseeing the delivery of particularly powerful armaments.
Modus Operandi
In battle, a hierrmagon enhances allies before entering the fray. It summons lesser devils, fortifies weapons with infernal enchantments, and then advances with devastating coordination.
Its four warhammers strike in seamless rotation, overwhelming opponents through relentless impact rather than reckless fury. Should a fight turn unfavourable, it withdraws strategically — often teleporting away to preserve its invaluable expertise.
Motivation
The hierrmagon exists to sustain Hell’s war machine. It is driven not by rage, but by duty — an unyielding compulsion to craft ever-deadlier weapons for the eternal Blood War.
Souls are raw materials. Battlefields are proving grounds. Perfection in metallurgy is devotion.
To disrupt its forge is to disrupt Hell’s supply lines — and such interference invites swift, calculated annihilation.

Description
A towering, four-armed devil of bronze-hued flesh, the Hierrmagon hammers molten weapons in the infernal forges of Avernus. Its corded muscles flex with perfect rhythm as each warhammer strikes red-hot metal, sulfurous smoke curling from its fanged maw. Backward-curving horns crown its head, and a thick, spiked tail drags sparks across the stone floor. Rarely leaving its forge, it empowers infernal legions with enchanted steel while crushing any who dare approach.

Teleport. The hierrmagon uses Greater teleport to move up to 120 ft. without provoking opportunity attacks.
Behavior
Hierrmagons rarely enter combat unprepared. They summon allies, cast defensive buffs, and use their four-armed mastery to dominate the battlefield. If threatened beyond their control, they retreat via teleportation, preserving their invaluable infernal craftsmanship.

Hierrmagon (Hellsmith)
Theodor Hummel
This four-armed, bronze colored creature stands 9 feet tall. It holds massive hammers in all of its four hands.
With an oddly beautiful rhythm, it alternates each arm as it strikes the red, hot metal before it. Sulfurous smoke billows from its gaping maw, which is lined with cruel pointed fangs. A pair of curving horns crowns its head, while a long, thick tail drags behind it. Magma bubbles from its flared nostrils when the creature notices you, and it advances with sudden speed, each arm poised to strike.
The hierrmagon is the armorer of Hell. It endlessly toils at its forge, churning out weapons for the Blood War. As such, one is almost never summoned to the Mortal Coil (and woe betide those who do attempt to take one away from its work.) With the help of the Soul Forges, it creates magical weaponry for the elite of Perditions society from the spirits of damned mortals.

Combat
If a hierrmagon is actually involved in combat, which is rare, it immediately summons more devils and uses its buff spells before wading into combat with its hammers. If it is pressed, it will use mages sword to add to its already impressive amount of attacks. Finally, if it looks as if the tide has turned against the hierrmagon, it will use summon monster spells to add even more combatants to the fray before teleporting away.
Eldritch Smithing (Su): The hierrmagon is capable of creating magical items. It has an effective caster level equal to its HD. It can use its spell-like abilities as the prerequisites for special item abilities. A hierrmagon must still have access to the proper spells in this manner or from scrolls to create magical items. A hierrmagon must still possess the proper feats to create magical items. Hierrmagons with 21 or more Hit Dice may take epic Item Creation Feats. Gold and XP costs are not reduced for the hierrmagon, although most work with a Soul Forge.
Quick Creation (Ex): Because of its 4 arms, a hierrmagon is capable of producing items at a much faster rate than normal. Its Craft checks to determine progress per day are done in silver pieces rather than copper, and its checks per week are done in gold pieces rather than silver. This has no effect on time spent enchanting weapons.
Spell-like Abilities:
- At will – greater teleport, scorching ray (3 rays);
- 3/day – bull’s strength, fireball, keen edge, mage armor, resist energy, resistance, shield;
- 1/day – mages sword, orders wrath, summon monster VI, unholy blight.
Caster level 12th; DC 10 + spell level.
Summon Devils (Sp): Once per day, a hierrmagon can attempt to summon 2d4 Bearded Devils with a 60% chance of success. This is equivalent to a 5th level spell.
Skills: A hierrmagon receives a +4 racial bonus on all Craft checks dealing with metal.
Feats: In combination with its natural abilities, a hierrmagon’s Multiweapon Fighting feat allows it to attack with all of its arms at no penalty.

BEHAVIOR
Hierrmagons are tireless infernal artisans, rarely engaging in combat directly. They summon devils and cast buffs before striking with their four-armed mastery. If threatened beyond control, they retreat via teleportation to preserve themselves, leaving summoned devils and apprentices to defend the forge. Their motivation is purely utilitarian: perfection in weapon crafting fuels Hell’s war machine, and they defend their forges ruthlessly.
