Inferno

The Inferno is the demon town of Heroes of Might and Magic 3, an evil town native to lava whose heroes are the Demoniac and the Heretic; it recruits Imps, Gogs, Hell Hounds, Demons, Pit Fiends, Efreet and Devils, each with an upgrade, and is known for the Arch Devil, the Castle Gate and the Pit Lords' raising of Demons.

The Inferno is the town of the Kreegan demons of Eeofol in Heroes of Might and Magic 3: native to lava, led by Demoniacs and Heretics, and recruiting Imps, Gogs, Hell Hounds, Demons, Pit Fiends, Efreet and Devils, which upgrade to Familiars, Magogs, Cerberi, Horned Demons, Pit Lords, Efreet Sultans and Arch Devils. It is known for the teleporting Arch Devil, for the Castle Gate that links its towns, and for Pit Lords that raise fallen stacks as Demons; the official strategy guide also warns that it has the weakest creature in the game, the Imp, and no flyer below level 7. It is one of the eight towns of the 1999 game, The Restoration of Erathia.

Inferno creatures

The numbers below are The Restoration of Erathia's, from the official strategy guide, pp.115 and 138-141: attack, defense, damage, health, speed in hexes, weekly growth of the basic dwelling, and cost. The Shadow of Death manual lists no changes to Inferno creatures (SoD manual, pp.24-25).

Level	Creature	Attack	Defense	Damage	Health	Speed	Growth	Cost (gold)
1	Imp	2	3	1-2	4	5	15	50

7	Arch Devil	26	28	30-40	200	17 (teleports)	1	4,500 + 2 mercury

Imps are, in the guide's words, "the weakest creature in the game". Familiars Channel: when an enemy casts a spell, 20% of the spell points spent go to the Familiars' hero (pp.138, 141). The Birthing Pool adds 8 Imps a week (p.115).

Gogs shoot; Magogs throw a Fireball that also hits the hexes next to the target, allies included (p.138).

Cerberi strike the target and the hexes on either side of it with their three heads; the Cages add 3 Hell Hounds a week (pp.115, 139).

Pit Lords can, instead of attacking, raise a slain allied stack of any creature as Demons, no more Demons than there are Pit Lords. The guide's tip: "convert dead stacks of Imps and other low-level creatures into level 4 Demons" (pp.140-141).

Efreet and Efreet Sultans are immune to Fire Magic and do 150% damage to the Tower's Genies; Sultans carry a Fire Shield that returns 20% of the damage they take (p.140).

Devils and Arch Devils teleport across the battlefield, lower the enemy's luck by 1, can't be struck back when they attack, and do 150% damage to the Castle's Angels, which do the same to them (Castle; p.141). Every creature's full entry is on Creatures.

Inferno heroes

The Inferno's two classes, from the official guide (pp.40-41 and 44-45); each has eight heroes in the 1999 game (Heroes):

Class	Starting Attack / Defense / Power / Knowledge	Starting skills
Demoniac	2 / 2 / 1 / 1	Combat and scouting skills such as Offense, Armorer, Tactics
Heretic	1 / 1 / 2 / 1	Wisdom with a second skill, for every Heretic

Which class is the might class is muddled in the guide: its text calls the Heretic "the might-oriented Hero of the inferno town" and says the Demoniac's skills split "60/40 ... in favor of magic", but its own tables give the Demoniac the starting statistics of the other might classes (2/2/1/1, like the Knight) and combat skills, and give every Heretic Wisdom, like the magic classes (pp.40-45). Read by those tables, the Demoniac is the might class and the Heretic the magic class.

Demoniacs: Calh (Gogs), Fiona (Hell Hounds), Ignatius (Imps), Marius (Demons), Nymus (Pit Fiends), Octavia (+350 gold a day), Pyre (Ballista), Rashka (Efreet) (p.41).
Heretics: Ash (Bloodlust), Axsis (Mysticism), Ayden (Intelligence), Calid (+1 sulfur a day), Olema (Weakness), Xarfax (Fireball), Xyron (Inferno), Zydar (Sorcery) (p.45).
Xeron, a Demoniac of Armageddon's Blade, gives Devils and Arch Devils +4 Attack, +2 Defense and +1 Speed (AB manual, p.9).

Buildings and the Grail

The Inferno's own buildings, from the guide (p.115):

Brimstone Stormclouds (1,000 gold and 5 sulfur): +2 Power for the garrison hero in a siege.
Castle Gate (10,000 gold, 5 wood and 5 ore, needs a Citadel): a visiting hero can teleport to another of the player's Infernos that has a Castle Gate.
Order of Fire (1,000 gold and 5 wood, needs Mage Guild I): +1 Power, once per hero.
Birthing Pool (1,000 gold): +8 Imps a week.
Cages (1,000 gold): +3 Hell Hounds a week.
Forsaken Palace, the Devil dwelling: 15,000 gold, 10 wood, 10 ore and 20 mercury.

"In terms of construction cost, the Inferno is dead middle in the pack," the guide says; mercury "is in high demand", for buildings and for recruiting Devils and Arch Devils, and the Resource Silo gives 1 mercury a day. It also notes how fast the level 4 Demon Gate goes up: an Inferno start very likely has its prerequisites built on day 1 (pp.109, 115). The Inferno's Grail building, the Deity of Fire, makes every week a Week of the Imp, besides the +50% creature growth and 5,000 gold a day every Grail building gives (p.111). General building advice is on Town Build Order.

How the Inferno plays

The guide's assessment (p.141): the Imp is "a major disadvantage to low-level Inferno armies", but the multi-hex attacks of Cerberi and Magogs "can be quite effective", so use Imps to guard the Magogs or to soak up counterstrikes before the Cerberi attack. Demons, Pit Fiends and Efreet are "average hand-to-hand attackers for their levels", and the upgrades to Pit Lord and Efreet Sultan are worth their cost, "especially" for the Pit Lords' raising of Demons. With no flying or teleporting creature below the Devil and no strong shooter, Inferno armies are "at quite a disadvantage when attacking fortified towns"; the guide suggests a hero with Ballistics, or Earth Magic and the Earthquake spell. Like the Archangel, the Arch Devil "is fast enough to cross the battlefield in a single move". More on fighting is on Combat.

2:10 Quick Save's town ranking puts the Inferno eighth of nine: it likes the demonic design but finds most units weak for their cost, singling out the Pit Lords' raising of Demons, the Efreet's fire spells with Armageddon, the Hell Hounds' three-headed attack and the Castle Gate, "extremely useful in larger maps". That is Quick Save's opinion, not the official guide's.

The Inferno in the campaigns

7:45 The Inferno is the town of Eeofol and its Kreegans. In The Restoration of Erathia's first evil campaign, Dungeons and Devils, Nighon and Eeofol attack Erathia, ending with Steadwick's Fall: "capture the city of Steadwick within three months" (p.297). Catherine's Liberation campaign answers with a scenario called Deal with the Devil (p.311). Armageddon's Blade is the Inferno's story: after the slaying of King Xenofex, Lucifer Kreegan rules Eeofol and has the legendary Armageddon's Blade forged, "which has the power to set the world on fire", and Catherine invades Eeofol to dethrone him (AB manual, pp.2-3, 9). In the end Gelu claims the Blade and slays Kreegan (Wikipedia). The Remake keeps the story: its gameplay overview promises that players will "face the apocalyptic threat of Armageddon's Blade" in its new campaign cinematics. The full stories are on Campaigns.

The Inferno in the Remake

Ubisoft's store screenshots for the Heroes of Might and Magic 3 Remake show horned devils and demons on the steps of a fiery fortress, and a horned, red-skinned devil stands beside a crowned, red-haired swordswoman in its key art. Ubisoft says "from day one, players will have access to all factions", and on Oct 7, 2026 said it had "begun refining several creature models" after feedback on the units' designs (Ubisoft on Steam). It has not listed changes to the Inferno's creatures or buildings, as of Oct 21, 2026.
