Editing Random Map

'''Random Map''' is a game feature that allows the computer to generate a map based on the given settings. The Random Map can be made directly in-game as well as on the Map Editor. 

== How Random Maps are formed ==
* There are several rules that Random Maps always follow, these include, but are not limited to the following. 

=== Towns ===
* Player owned towns will often spawn on their [[native terrain]]. The only exception is Necropolis (often starts underground on Subterranean if the map is 2 layers) and [[Dungeon]] (often starts on dirt).
* The players starting towns start with a tavern, a village hall, the level 1 dwelling, sometimes the level 2 dwelling and almost always a Fort. Players can occasionally spawn with two towns each, but most commonly one town. Neutral towns start with the same as the player towns, but with no tavern and sometimes no Fort.
* A [[sawmill]] and an [[ore pit]] will always spawn within close proximity to all player-owned starting towns. However, due to the naturally generated obstacles around the towns, the walking distances to these resource generators sometimes becomes very long, especially on larger maps.

=== Heroes ===
* Creating a random map before selecting the players' starting heroes will result in some heroes being unavailable as starting heroes because they will be placed in the prisons scattered across the Adventure Map.
* The players' starting heroes will usually start at level 1, but sometimes on higher levels. This can only occur if the player's hero ''was chosen by the player before the random map was created''. Should this happen, it will cause one of the prisons on the map to be empty, because the player's starting hero were meant to be locked in there. The highest level a hero can start in is 20. This is likely a bug, and has been removed in the [[Horn of the Abyss]] expansion. 

=== Adventure Map ===
* All Random Maps are filled with resources, mines and almost everything that can be found in the [[Adventure map|adventure map category]]. There are however some structures that never appear on the world map, such as [[Border Guard]]s, [[Border gate]]s, [[Quest Guard]]s, [[Keymaster's Tent]]s, [[Freelancer's Guild]]s and [[Tavern]]s. 
* [[Spell Scroll]]s are very common and will spawn both with and without guards. The guarded spell scrolls will contain level 2-5 spells, while those that are not guarded contains level 1 spells. The level 2-5 spell scrolls are often poorly guarded even when the monster strength is set to "strong" (an [[Implosion]] scroll can spawn with as few guardians as 24 [[serpent fly|serpent flies]])
* The Map will often contain [[prison]]s, where heroes with 0, 5000, 10000, 15000 or 20000 experience are located.
* There are roads on all Random Maps, connecting most [[Monoliths|portals]], [[Subterranean Gate]]s and towns.
* The world map is divided into regions, where each region has a certain terrain and oftem accommodate a certain faction that is native to that terrain. For example, a region with Grass terrain might contain one or more [[Castle]] towns and Castle [[Creature Dwelling]]s, and all creature rewards from Pandora's Boxes and Seers' Huts in that region will contain Castle creatures. Neutral troops can be guarding the roads between regions depending on what the Random Map's monster strength is set to.
* Wandering Monsters on random maps are set with the aggressiveness level "Hostile", meaning that they will almost never join a hero unless the hero has [[Diplomacy]]. This happens regardless of the monster strength that the creator of the map has declared. Creatures spawned by [[Special month]]s are the only exception; these creatures are more likely to join heroes, and can do so without the use of Diplomacy.

==== Pandora's Boxes ====
* Guarded [[Pandora's Box]]es frequently spawn across the map containing:
**5.000, 10.000, 15.000 or 20.000 [[Experience]] or [[gold]] (the box gives experience '''40%''' of the time, and gold '''20%''' of the time)
**All [[Spells]] of either a certain level, or belonging to a certain school (the box gives spells '''20%''' of the time).
**A number of [[creature]]s, ranging from 250 ([[Peasant]]s) to 3 (High level creatures) (the box gives creatures '''20%''' of the time).
*** The rewards are proportional to the strength of its guardians (the stronger guardians, the greater reward).
***Note that the box may sometimes appear to be empty when opened, and thereby disappear without giving any reward. If this happens, it means that the Box contained spells that your hero either were unable to learn (due to the lack of a [[Spell Book]] or a sufficient level in [[Wisdom]]) or already knew.

==== Seer's Huts ====
* [[Seer's Hut|Seers' Huts]] spawn with no guardians, searching for a random artifact usually somewhere on the map. In return for the artifact they, they give rewards from a reward pool similar to that of the Pandora's Boxes (with the exception of spells, which they don't give at all). Creatures are given approximately '''50%''' of the time, while Experience and Gold are, respectively, given approximately '''25%''' of the time. 
** Unlike the Pandora's Boxes', the Seers' Huts' rewards are not proportional to the artifact they look for (it is for example possible that they give 3 [[Archangel]]s for a [[Centaur's Axe]], but merely 30 [[Harpy Hag]]s for the [[Mystic Orb of Mana]]). Instead, the rewards are proportional to the guardians of the artifact. For example, a Seer's Hut can give as many as 5 [[Devil]]s for the nearly worthless artifact [[Cards of Prophecy]] if it was found on the map being guarded a strong group of monsters (such as several [[hydra]]s). As such, if you find a common inexpensive artifact with powerful guardians on a Random Map, you can expect that a Seer will look for this artifact and give a significant reward in return for it.
**If a seer is looking for a particular artifact, that artifact will almost always be present somewhere on the Random Map, but never more than 1 artifact of the same type will spawn in this case. Note that Seers always will accept the type of artifact they are looking for, even if it was not found on the adventure map. This makes the [[Artifact Merchants]] structure in the [[Dungeon]], [[Conflux]] and [[Tower]] town extra valuable on some Random Maps.
** The rewards can include the following: 
*** Creatures: The creature rewards range from small rewards such as 80 [[Troglodyte]]s, 50 [[Wolf Rider]]s or 35 [[Obsidian Gargoyle]]s, to larger rewards such as 15 [[Mighty Gorgon]]s, 10 [[Champion]]s, 5 [[Devil]]s or 1 [[Rust Dragon]]. Measured in [[AI value]], these rewards range between about 5000-25000 in total. 
*** Gold: 5000, 10000, 15000 or 20000
*** Experience: 5000, 10000, 15000 or 20000.

== Customizing Random Maps == 
Before creating a Random Map, the player can specify how it will look.

;Size
* The player may choose between Small (36x36), Medium (72x72), Large (108x108) and Extra Large (144x144) map size.

;Levels
* The player may choose between one or two levels on the map. The underground [[layer]] will never contain water, only [[Subterranean]] and occasionally [[Lava]] (if an [[Inferno]] town is located there, as they will spawn on lava terrain). The overworld can contain anything except Subterranean terrain. 

;Human/Computer Players
* The player may choose how many human players can be avalible on the map. Up to eight players may be in the game (humans and computers included).

;Computer Players
* The player may choose the amount of computer players that is on the map. These players can only be played by the computer AI.

;Human/Computer Teams
* Between 1 and 8 human or computer teams can be choosen by the player. 

;Monster Strength
* The player may choose the neutral monsters to be weak, medium or strong. Choosing weak will cause most mines, dwellings and artifacts to have no guardians, while choosing strong will cause all mines (except sawmills and ore mines), all artifacts (except [[Spell Scroll]]s) and all primary skill increasing structures (like [[Mercenary Camp]]s) to be guarded.

;Water content
* The player may choose between no water at all, some water, or islands. Choosing islands will cause the majority (75%) of the map to be covered with water, leaving each player with an own island. All islands will have a [[Shipyard]] and very commonly portals connecting the islands to each other.

== Bugs ==
* The Random Map will sometimes spawn with water even though "no water" was not selected.
* Sometimes a player will spawn completely surrounded by obstacles, making it impossible to reach him/her unless [[Fly]], [[Dimension Door]]   or [[Angel Wings]] is avalible.
**This bug is very rare on smaller maps, but occurs occasionally on larger maps.
* Resources, artifacts and Pandora's Boxes will sometimes spawn with insufficient obstacles around them, making it possible to take them without defeating their guardians. This can easily be game-ending especially on smaller maps.
* Valuable resources, mines, artifacts or Pandora's Boxes will sometimes spawn with no guards at all, or with weak guards (e.g. 30 [[Wolf Rider and Wolf Raider|Wolf Raiders]] guarding [[Resurrection]] spell scroll).

== Horn of the Abyss ==
Adds a random map [[Template Editor|template editor]] and [[Horn_of_the_Abyss_(Documentation)#Random_Map_Generator|greatly improves the generated maps]].
