Demon

Demons are a class of monster mostly found in Gehennom. The class is not synonymous with the monsters represented by the & symbol: the riders and djinn are not demons, and the i class is comprised of minor demons. The mail daemon is technically a member of this class, but is not generally viewed as an actual monster.

Although minor demons are not a significant threat, major demons are quite strong opponents, and can summon other major demons (with the exceptions of balrogs, incubi and succubi). Sacrificing your own race can summon a demon lord, as can angering your god when on an altar (by praying with negative alignment, or praying too often, amongst other effects) if you are chaotic.

The minor demons are:

• i, manes
• i, lemures
• i, homonculi
• i, imps
• i, quasits
• i, tengu

The ordinary major demons are:

• &, water demons
• &, horned devils
• &, succubi
• &, incubi
• &, erinyes
• &, barbed devils
• &, mariliths
• &, vrocks
• &, hezrou
• &, bone devils
• &, ice devils
• &, nalfeshnees
• &, pit fiends
• &, balrogs

Unique demons and summoning

The named demons are divided into two ranks: demon lords and demon princes.

The demon lords are:

• &, Juiblex
• &, Yeenoghu

The demon princes are:

• &, Orcus
• &, Geryon
• &, Dispater
• &, Baalzebub
• &, Asmodeus
• &, Demogorgon

Every major demon has a 1/13 chance of summoning another major demon each turn. The difference between demons, demon lords, and demon princes lies in which other demons they can summon, and how often. See the Demon summoning spoiler for details.
