View source for Imp or minor demon

The '''imp or minor demon''' is a [[monster class]] that appears in ''[[NetHack]]'', and is represented by the lowercase [[i]] glyph ({{white|i}}). Imps and minor demons are designated internally by the macro '''S_IMP'''.{{refsrc|include/monsym.h|23|version=NetHack 3.6.7}}

The class contains the following monsters:{{refsrc|src/monst.c|467|version=NetHack 3.6.7}}

* {{monsymlink|manes}}
* {{monsymlink|homunculus}}
* {{monsymlink|imp}}
* {{monsymlink|lemure}}
* {{monsymlink|quasit}}
* {{monsymlink|tengu}}

==Common traits==
All monsters in the class except the tengu are vulnerable to [[silver]], taking an extra d20 damage when struck with a silver item{{refsrc|src/mondata.c|307|version=NetHack 3.6.7|comment=<code>hates_silver</code> function}} - this makes the tengu fairly distinct from other members of its class. The minor demons themselves are distinct from the "major" [[demon]]s due to lacking the <code>[[M2_DEMON]]</code> flag{{refsrc|src/mondata.c|594|version=NetHack 3.6.7}}{{refsrc|src/mondata.c|599|version=NetHack 3.6.7}} - for instance, minor demons do not [[Death resistance|resist death magic]] or take damage from {{! of|holy water}}.

===Generation===
The imp or minor demon is the first [[quest]] monster class for [[Knight]]s, and makes up {{frac|24|175}} of the monsters that are randomly generated on the [[Knight quest]]. Random imps and minor demons are also generated on some levels of the quest below the home floor at level creation: one each is generated on the locate and lower filler level(s), and two are generated on the goal level.

Random imps and minor demons are also generated on all levels of the [[Wizard quest]] at level creation: two are generated on the home level; four are generated on the upper filler level; eight each are generated on the home level and goal level; and three each are generated on the lower filler level(s).

==History==
The imp, homunculus and quasit first appear in Hack for PDP-11, which is based on [[Jay Fenlason's Hack]] - all three are included in the initial bestiary for [[Hack 1.0]] alongside the tengu, which makes its debut in this version. In [[NetHack 2.3e]], the quasit only appears if the KAA [[compile-time option]] is ''not'' defined, and is otherwise replaced by the [[quantum mechanic]] (who is introduced in this version).

The imp or minor demon monster class first appears in [[NetHack 3.0.0]] - the imp, homunculus, quasit, and tengu are moved to the {{white|i}} glyph, the [[manes]] and [[lemure]] are introduced, and the quasit is made part of the default bestiary.

==Variants==
===SLASH'EM===
[[SLASH'EM]] introduces a few new monsters to the class:

* {{monsymlink|dretch}}
* {{monsymlink|rutterkin}}
* {{monsymlink|nupperibo}}
* {{monsymlink|blood imp}}

The imp or minor demon is the second quest monster class for [[Necromancer]]s, and makes up {{frac|6|175}} of the monsters randomly generated on the [[Necromancer quest]]. Several of them are also generated on floors above the goal level of the quest branch at level creation: two are generated on the home level, four are generated on the upper filler level, and five each are generated on the locate and lower filler level(s).

===xNetHack===
In [[xNetHack]], all minor demons including tengu hate the touch of [[iron]], taking an extra d6 damage when struck with an iron item.
