Demons Type I-VI

[The Red King]

Note that this is not the case in original D&D - Eldritch Wizardry, where they were introduced.

Seven demons and two demon princes are in that book, and what sets the succubus apart from the "type" demons is that the Succubus is encountered alone, whilst the Type I-VI demons are encountered typically in numbers (1-6 in lair, 1-3 when roaming); there was a 25% chance that if encountered in the lair there would be 1-6 demons, with the type of each determined by a die roll!

Not one of the "type" demons has a name in their descriptions, nor the possibility of names.

Cheers!

I think thats right. They Typed demons couldnt have names, while the others could.

Wasn't there also something about true, greater, lesser, and least demons?

The quasit, a frequent servant of demons, also first appeared in the original Monster Manual.

Lolth, the Demon Queen of Spiders is described under the demon entry in the Fiend Folio (1981)

Several new demons debuted in the module Lost Caverns of Tsojcanth (1982), including the alu-demon (demi-demon), the bar-lgura (minor demon), the chasme, the dretch, and the rutterkin (minor demon), and new demon lords Baphomet, Fraz-Urb'luu (Prince of Deception), Graz'zt (demon prince), and Kostchtchie (demon lord).

In the 1E Monster Manual lesser demons are destroyed when killed on the Material Plane while greater demons are only banished back to the Abyss. Lesser demons were types I-III (or maybe I-IV) while the higher types were greater demons. In Monster Manual 2 Gary seems to have gone from "lesser" and "greater" to "minor" and "major" but its the same idea I suppose.

"True" as an adjective for demons is a second edition thing. Of course deomns were "tanar'i" by then, but stil...
