'''Monster generation''' determines which creatures appear, where they are placed and which possessions and abilities they begin with. Ordinary dungeon populations, countryside encounters, fixed scenes and [[Draft:Summoning|summoning]] do not all use the same selection rules. A monster's listed level is a template value, not a guarantee of when it can appear or how dangerous it will be.<ref>{{Source|lev.c|11|239}}; {{Source|lev.c|262|399}}; {{Source|effect3.c|7|43}}.</ref>

__TOC__

== Random selection ==
The ordinary difficulty-based selector draws from the beginning of the monster catalogue up to a difficulty-dependent boundary, retrying any template reserved for special construction. It includes lower-level creatures rather than choosing only creatures of the current difficulty.<ref>{{Source|lev.c|280|311}}; {{Source|defs.h|1071|1094}}; {{Source|minit.h|5|306}}.</ref>

{| class="wikitable"
! Difficulty !! Template level bands considered !! Eligible ordinary templates
|-
| 0 || 0 || 8
|-
| 1 || 0–1 || 30
|-
| 2 || 0–2 || 44
|-
| 3 || 0–3 || 58
|-
| 4 || 0–4 || 76
|-

|-

|-
| 8 || 0–8 || 129
|-
| 9 or higher || 0–9 at difficulty 9; all bands at 10 or higher, with no additional eligible templates || 137
|}
Within a permitted range the templates have approximately equal weight, not equal weight per level band. The counts above describe the ordinary pool, not every creature which can appear in that location. The random helper divides 10,000 buckets into the requested range, so fractions such as one third or one twelfth below are nominal weights with slight rounding differences.<ref>{{Source|util.c|26|31}}; {{Source|lev.c|280|311}}.</ref>

=== Difficulty by location ===
Let D be the current dungeon depth. Division in these formulas rounds down. Player level does not directly enter this difficulty calculation.<ref>{{Source|lev.c|465|497}}.</ref>

{| class="wikitable"
! Location !! Difficulty
|-
| [[Draft:Goblin Caves|Goblin Caves]] || floor(D / 3) + 1
|-
| [[Draft:Rampart Sewers|Sewers]] || floor(D / 6) + 3
|-
| [[Draft:Archmage's Castle|Archmage's Castle]] || floor(D / 4) + 4
|-
| [[Draft:HellWell Volcano|HellWell Volcano]] || floor(D / 4) + 5
|-
| Astral Plane, Circle, Magic Isle, main temples || 8
|-

|-
| Rampart; hovels || 3
|-
| Villages || 1
|-
| Arena; ordinary houses || 5
|-
| Dragon's Lair; Star Peak || 9
|-
| Abyss || 10
|}

=== Other random paths ===
The countryside tables' '''wildcard''' is different: it directly chooses a template from bands 0–8 without the ordinary special-template rejection. It can therefore produce a [[Draft:Goblin King|Goblin King]], [[Draft:Great Wyrm|Great Wyrm]] or [[Draft:Historical officeholder|historical officeholder]]. Terrain without a dedicated table instead uses the ordinary difficulty-based selector. Unrestricted hostile summoning draws from all 150 templates, including creatures beyond both of these pools.<ref>{{Source|lev.c|47|66}}; {{Source|lev.c|316|394}}; {{Source|effect3.c|7|43}}.</ref>

Fixed construction does not enforce a global one-living-copy limit on a named creature. A particular quest or map loader can still suppress its own placement after completion. Treat those location flags and the ordinary random-pool filter as separate rules.<ref>{{Source|lev.c|262|277}}; {{Source|lev.c|316|394}}; {{Source|gen1.c|394|431}}; {{Source|gen2.c|412|433}}.</ref>

== Dungeon populations ==
When a dungeon floor is generated, its ordinary population has '''3 × (R(floor(difficulty / 3)) + 1) + 8''' placements, where R(N) returns a value from 0 through N - 1 and R(0) is zero. Add ten in the Castle or Astral Plane and twenty in the Volcano. Fixed inhabitants are additional to this population.<ref>{{Source|gen1.c|87|125}}; {{Source|lev.c|78|239}}.</ref>

Placement searches for an unoccupied, nonsecret floor square. Water-only creatures have their starting square changed into water. The selector does not require a square outside the player's view, and its ordinary floor search has no check excluding the player's own coordinates.<ref>{{Source|util.c|578|639}}; {{Source|lev.c|89|92}}; {{Source|lev.c|214|229}}.</ref>

=== Goblin Caves ===
For each placement, the game tries the shaman roll first, then a separate chieftain roll, then the goblin roll. Define S = clamp(10D - 51, 0, 100) / 100 and C = clamp(10D - 1, 0, 100) / 100.<ref>{{Source|lev.c|94|103}}.</ref>

{| class="wikitable"
! Selection branch !! Weight
|-
| [[Draft:Goblin shaman|Goblin shaman]] || S
|-
| [[Draft:Goblin chieftain|Goblin chieftain]] || (1 - S) × C
|-
| [[Draft:Goblin|Goblin]] || (1 - S) × (1 - C) × 49 / 100
|-
| Ordinary random pool || (1 - S) × (1 - C) × 51 / 100
|}
The random branch can itself select one of the goblin types if its difficulty permits it, so the table is not the final species probability. At depth 1 the direct branches are 0% shaman, 9% chieftain and 44.59% goblin; the remaining 46.41% uses the ordinary pool.

=== Sewers ===
One third of placements use the ordinary random pool immediately. Otherwise roll an index from 0 through D + 2 and consult this table; any index beyond 15 also uses the ordinary pool. Each available listed index therefore has nominal branch weight '''2 / (3 × (D + 3))'''.<ref>{{Source|lev.c|104|126}}.</ref>

|-
| 7 || [[Draft:Acid cloud|Acid cloud]] || 15 || [[Draft:Rodent of unusual size|Rodent of unusual size]]
|}

=== Astral Plane ===
Half of placements choose from the first list below. A further quarter chooses the current plane's elemental on depths 1–4, or a creature from the deep-Astral list on depth 5. The remaining quarter uses the ordinary difficulty-8 pool. Each member of a twelve-entry list has nominal branch weight 1/24 or 1/48 respectively, before any additional chance through the ordinary pool.<ref>{{Source|lev.c|127|165}}.</ref>

{| class="wikitable"

|}

=== Volcano and Castle ===
In the Volcano, half of placements choose an ordinary template from bands 4–9, irrespective of the current ordinary difficulty ceiling. Otherwise choose an index from 0 through floor(D / 2) + 1. The following are the reachable indexed entries within the twenty-level dungeon; each available index has nominal branch weight '''1 / (2 × (floor(D / 2) + 2))'''.<ref>{{Source|lev.c|166|196}}; {{Source|defs.h|156}}; {{Source|aux2.c|1078}}.</ref>

{| class="wikitable"
! Index !! Creature !! Index !! Creature
|-
| 0 || [[Draft:Haunt|Haunt]] || 6 || [[Draft:Fire elemental|Fire elemental]]
|-
| 1 || [[Draft:Incubus and succubus|Incubus or succubus]] || 7 || [[Draft:Lich|Lich]]

|}
The source has further indexed cases starting at 12, but the normal depth limit never selects them. This does not exclude those species from the Volcano: eligible ordinary templates can still arrive through its first, level-4–9 branch or later wandering checks.

In the Castle, one quarter of placements chooses an [[Draft:Enchanter|enchanter]] at difficulty below 5, a [[Draft:Necromancer|necromancer]] at difficulty 5, a [[Draft:Fire elemental|fire elemental]] at difficulty 6–7, or a [[Draft:High thaumaturgist|high thaumaturgist]] at difficulty 8 or higher. The other three quarters use the ordinary pool.<ref>{{Source|lev.c|197|210}}.</ref>

=== Later arrivals ===
Ten-minute checks, including the hourly check which replaces every sixth one, try to add a wandering creature when the current environment is the current dungeon. The test is R(maximum dungeon levels) < difficulty, giving nominal chance difficulty / maximum levels, capped at certainty. This uses the ordinary difficulty pool, not the initial themed table. Waiting on a cleared dungeon floor can therefore bring new occupants.<ref>{{Source|aux3.c|11|47}}; {{Source|lev.c|246|257}}.</ref>

== Countryside encounters ==
An outdoor tactical population makes '''(R(5) + 1) × (R(3) + 1)''' placements. This is a product, not a uniform choice from 1 through 15. Each placement independently chooses one of ten slots from the applicable terrain table. Repeated entries below are shown as weights out of ten; ''wildcard'' has the less restricted meaning explained above.<ref>{{Source|lev.c|11|70}}.</ref>

{| class="wikitable"
! Terrain !! Ten selection slots
|-
| Plains || Rabbit ×2; hornet, quail, hawk, deer, wolf, lion, brigand, wildcard ×1 each
|-
| Forest || Deer ×2; rabbit, quail, hawk, badger, wolf, bear, brigand, wildcard ×1 each
|-
| Jungle || Giant soldier ant ×2, hyena ×2; anteater, parrot, mamba, elephant, lion, wildcard ×1 each
|-
| River || Trout ×2, striped bass ×2, giant crocodile ×2; quail, man o' war, brigand, wildcard ×1 each
|-
| Swamp || Striped bass ×2, giant crocodile ×2, giant soldier ant ×2, wildcard ×3; bog thing ×1
|-
| Desert || Hawk, camel, hyena, lion, wildcard ×2 each
|-
| Tundra || Wolf ×2, bear ×2, deer ×2, wildcard ×4
|-
| Mountains, passes, volcano terrain || Hawk ×3, wolf ×2, wildcard ×3; rabbit and sheep ×1 each
|}
These weights describe one placement inside an encounter, not the chance that travelling on a terrain square triggers a fight. All resulting creatures receive awareness equal to the map width. Coordinates are chosen without the dungeon's empty-floor search, so placements can collide; the number requested is not a promise of that many distinct visible occupied squares. Water-only creatures receive water at their starting position.<ref>{{Source|lev.c|35|70}}; {{Source|aux2.c|1160|1186}}.</ref>

== Construction and variants ==
Ordinary construction copies the species, applies identity-specific changes, and may set it awake. With no pre-existing awake flag, a sleep rating S is beaten when a random 0–99 roll is strictly greater than S: a rating of zero is initially awake on 99% of constructions, while 100 never passes this roll. Wakeup on approach is a later [[Draft:Monster behavior|behavior]] check.<ref>{{Source|lev.c|316|394}}; {{Source|mon.c|12|30}}.</ref>

A fixed starting item is copied from its current base definition when its uniqueness state permits it. Additional random possessions number from zero through treasure allowance minus one, with zero allowance giving none. Those additional objects must be ordinary items; a reserved unique object is rejected and another is tried. Fixed equipment and extra random loot are thus different sources. Possessions also do not replace the creature's innate attack ratings.<ref>{{Source|lev.c|373|394}}; {{Source|mmelee.c|8|51}}.</ref>

[[Draft:Historical adventurer|Historical adventurers]] and [[Draft:Historical officeholder|officeholders]] use their own constructors. [[Draft:Were-human|Were-humans]] can later change form while retaining some earlier values. The [[Draft:Rampart Coliseum|arena]] instead copies a selected template directly, skipping ordinary starting loot, adds its exit opener, makes the opponent awake and named, adds ten HP per monster level, doubles hit, and adds half the original damage rating rounded down. Its late random matches exclude dynamic human templates and zero-damage templates; its fixed sequence and champion use separate rules.<ref>{{Source|lev.c|341|394}}; {{Source|mon.c|529|750}}; {{Source|mspec.c|407|440}}; {{Source|guild1.c|349|450}}; {{Source|env.c|63|76}}.</ref>

== Strategy ==
Use the location's actual population rules when judging risk. The early Volcano can select high-level ordinary creatures through its dedicated broad range, while an ordinary summoning spell in Rampart uses difficulty 3. A countryside wildcard can bypass exclusions that would protect the ordinary dungeon pool.

Do not assume a cleared floor remains clear indefinitely, or that seeing a familiar glyph guarantees an ordinary specimen. Arena and historical forms can have different stats and loot. Consult the [[Draft:Monster|creature directory]] for the actual species and [[Draft:Monster remains|Monster remains]] for death rewards; killing a creature and retrieving a quest trophy are separate stages.
