This file was originally automatically generated.

DIF is the monster's difficulty value. Monsters will start being eligible for random generation when the average of your experience level and your dungeon level is equal to DIF; they will be considered too weak for generation when your dungeon level is 7*DIF or greater. (For this purpose, once you have the Amulet of Yendor your dungeon level is considered to be that of the Sanctum, and in the endgame to be the depth of the Sanctum plus half your experience level.) The level of your god's appreciation of a sacrificed corpse is also dependent on the corpse's DIF.

FREQ is the relative frequency of monster generation. An X in this field means the monster will not be randomly generated, and only appears in certain circumstances or on predefined levels. A monster with 0 frequency will only be randomly generated in a dungeon branch or on a dungeon level biased towards a specific alignment (not necessarily its own). '*' denotes monsters that will not be randomly generated in Gehennom; '#' monsters that will not be randomly generated outside it.

The GRP field indicates if monsters are generated in large groups (2 to 11 monsters at a time) or small groups (2 to 4 monsters at a time). These groups will be smaller if you are at a low (less than 5) experience level. Large-group monsters have a 1/3 chance of being generated in a small group instead; small-group monsters a 1/2 chance of being generated as singletons.

ALN is the strength of alignment of the monster: positive numbers denote lawful monsters, negative chaotic, zero neutral. The Wizard of Yendor is non-aligned. Certain special levels and certain dungeon branches are biased towards creation of monsters of a specific alignment (see the NetHack Gazetteer for details); furthermore, lawful monsters will not be randomly generated in Gehennom.

The SIZE field shows the physical size of the monster. Though establishing a realistic scale for NetHack isn't something that can be easily done, the following guidelines are given (metric conversion approximate):

SIZE tiny small medium large huge gigantic
Scale < 2' 2'-4' 4'-7' 7'-12' 12'-25' "off the scale"
  (< 0.5m) (0.5m-1m) (1m-2m) (2m-4m) (4m-8m)  

WGT specifies the weight of the monster or its corpse (100 zorkmids weigh 1). Statues of that monster weigh (1.5 * WGT). NUTR specifies the nutrition value of a corpse when eaten (a monster swallowed whole gives half its nutrition). GEN indicates if a monster is able to be genocided.

CORPSE% gives the percentage chance of a monster leaving a corpse when killed (assuming the circumstances are such that it can leave a corpse at all; not disintegrated, digested, drowned, stoned...). No corpses will be left by monsters dying on the Rogue level. '#' indicates that the corpse left will be of a different monster (the human form of lycanthropes, the basic race for undead). Monsters marked with a '*' are less likely to leave corpses on levels with graveyards (for this purpose, the Castle and all levels of the Priest Quest are considered graveyard levels, as is any level on which undead have been summoned by the cursed Book of the Dead or Bell of Opening): 1/9 the chance if killed by you, 1/3 otherwise (eg, by a trap or another monster).
