Demon Construction Matrix by Dave Cecil (ZIP 133Kb)
From the vile depths of the lower planes boil forth horrific monstrosities beyond the comprehension of mortal men. Wizards, sorcerers and some powerful adventurers have seen and battled these fiends; yet they have only managed to scratch the surface of the abominable diversity of evil that lingers in everlasting hate in the seething bowels of the multi-verse. In the forgotten recesses of these tainted realms, there are more types of demonic entities than even the most studious sage could hope to study or document. Those adventurers that would dare venture into the most remote dimensions of evil will be unable to predict the kind of enemies they would face. The only constant is that all these beings are horribly, absolutely evil.
And now, the DM has a tool to allow the generation of an awesome diversity of demonic beings. Seasoned players know what to expect from a Vrock, and they are rarely fooled by a succubus, but now there will be no way to predict the onslaughts of their cackling dungeon master. The tables below permit the generation of random powers and traits for evil outsiders. Though the hit dice, and specific spell-like abilities, as well as resistances must be determined by the DM, these tables can provide a wealth of ideas for the form, appearance, and function of as many new demons as you care to create.
In order to create balanced creatures, the DM may wish to determine himself factors such as skill points and spell/like abilities. These abilities usually correlate with hit dice.

The Ferrulanguine is a chaotic evil, spherical mass of blood. The fiend floats of its own accord; and its unfortunate victims can see the heads of lions, goats, crocodiles, and assorted rare carnivores rising, surging out from within the bloody orb. It can attack but once with a single, bestial head inflicting 1d8 damage, but beware! For the Fiend hungers for the life-force of the living, and those bitten by the beast-heads will find their very essence drained from them! Many small weapons, daggers and the like cannot harm the bloody orb, with damage reduction 5/+1, it resists most causal harm. Beware, for the abomination may cast the following spell-like abilities 3 times a day each: Enervation; Scare; Stinking Cloud; Vampiric Touch. (Suggested CR; 3-5)

The Aurahmour is an alluring fiend of evil. In its natural state, it resembles a shapely human female of human or elven descent, yet its flesh is composed entirely of some glittering, golden alloy, with hooves for feet. Its reptilian tail marks it as a creature with a greed for treasure rivaling that of a dragons.’ and it conceals its true nature to achieve its designs. The Aurahmour possesses a magical alternate form; that of an entirely human-like woman, always of seductive beauty. In battle, a mighty weapon is required to penetrate the fiends’ 25/+3 damage reduction, though its own ability to deal damage is a mere 1d8; forcing it to depend on spell-like abilities.
The demon seeks men of wealth, or men on the verge of obtaining greater wealth. Its soft touch can drain a mortal of 2 points of wisdom, which never return unless the Aurahmour wishes it. After marrying a wealthy mortal, the fiend tempts him into greater acts of depravity and evil in the pursuit of wealth, for the entity craves riches for their own sake with a supernatural passion. It has no fleshly needs, yet it craves to live in luxury, until the demons’ deluded husband is finally destroyed by the crime and corruption it lured him into. The demon always manages to escape; revealing its true visage to its husband before the end. An Auramhour can cast the following spell-like abilities 3 times a day: Charm Monster; Leomund’s Secret Chest; Lightning Bolt; Mind Fog; Wall of Iron; Unhallow These abilities are cast as though by a 13th level sorcerer. (Suggested CR; 5-7)

The Terroreyn is the quintessential fiend; a skulking humanoid form composed of living darkness, with huge bat-wings to travel through the lower planes; in search of creatures to torment. Better still are those rare occasions when it finds a path to the material plane; that it might ravage mortal men. While the demon is quite capable of unleashing horrific damage with its spell-like abilities; it prefers to use nightmares and illusions to drive its prey into insane acts of self destruction. Few indeed can resist the madness and terror wrought by such a monstrosity.
The demon travels at night; its non-corporeal body gliding into homes of sleeping families, creating illusionary horrors and nightmare images to torment the unwary. It trusts in its virtual immunity to most conventional attacks as it challenges the puny humans to halt its depradations. Those that do manage to harm the fiend will find that the dark essence of absolute evil flows in its veins. Anyone inflicting damage in melee must succeed at a DC 15 reflex save or suffer 2d4 cold damage from the release of evil vapors. Once unleashed, a spree of terror and murder drench the lands in blood. But soon enough, those with power will surely marshall their forces against such a monstrous menace as the Terroreyn. All spells are cast as though by an 18th level sorcerer. (Suggested CR; 10-14)

The Vermindlith is a vile demon of sinister aspect. When loosed on the material plane; it travels in the form of a comely, young woman. Its true nature is similar in shape; also like that of a human female. But the flesh of the Vermindlith is a writhing; squirming mass of poisonous maggots and parasitic larvae; bound into the form of a shapely girl. The demon has black, vulture-like wings, through which the occasional maggot crawls, down towards the lengthy tapeworms that form the demon’s hair.
The Vermindlith prefers isolated rural villages; especially those preparing for a festival of some kind. It arrives during the festival in human form; dancing and joking and drinking and carousing with the local men. When dancing closely with a mortal man, or otherwise intimately entwined, the demon takes the opportunity to use its Contagion ability. The demon can choose to delay the onset for up to a week; giving her paramour the chance to spread his affliction to others before symptoms appear. Festivals are best for this purpose; the demon has an excuse to indulge itself in all manner of sensual pleasures while wreaking havoc.
They can be captured however; because a Vermindlith always returns to the scene of its ravages. It returns to revel in the pestilential carnage wrought by its plague; to exult in the horror of the shattered joy of the people. When annoying adventurers show up to spoil its fun, the demon assumes its natural form; releases a few maggots from its feathery wings, and casts Giant Vermin to keep its enemies busy. If an enemy gets too close, they must contend with the poisonous bites of the vermin that compose the demon’s body. All spells are cast as though the Vermindlith were a 13th level
