Zone tier: Difference between revisions

Revision as of 18:24, 21 June 2022

This article has information that is missing or not up to par.
Reason: Needs updated maps that include the Deep Jungle areas from the latest game version.

Each zone (or screen) that a player explores has a particular difficulty tier typically referred to as the Zone tier.

Zone tier is one significant factor that contributes to the procedural generation of features in Caves of Qud, such as the level and difficulty of creatures that are found in a particular zone, or the items that can be obtained as random loot from a chest in that zone. Procedural generation is also influenced by other factors, such as the terrain type of the current zone and whether or not the current zone is part of a village or a unique location.

Zone tier is determined based on a combination of the following elements:

The surface tier of the current world map parasangAn area made of 3x3 screens, which is represented as one tile on the overworld map..
The depth of the current zone, if it is underground.

Tiers and Procedural Generation

Elder Irudad with zetachrome pumps

A location's zone tier is generally used as a rough guide for procedural generation of creatures and items in that zone.

For example, in an area with a zone tier of 5, tier 5 creatures (such as dynamic turret tinkers) and tier 5 items (such as fullerite gauntlets) are more likely to be found. Note that zone tier is only one of several factors that affects the dynamic generation of creatures and objects in the world. Specific types of terrain, biomes, unique locations (such as historic sites or dungeons), or other factors can influence the objects and items that are generated in particular zones. This is why, for example, the surface levels of the desert canyons will always contain the same primary creatures, such as snapjaws, equimaxes, and giant dragonflies - this biome has its own unique population/encounter tables.

Most biomes have unique generation tables defined for their surface and levels 1-5 underground.^[1] Once you descend to level 6 or lower in most areas, creature and item generation more directly correlates to zone tier and is less strictly defined by terrain-specific spawning logic.

There is also an element of randomness at play. For example, the dynamic loot tables for each zone tier have a small chance to roll upward one tier higher. This effect can chain in succession (although at very low probability), sometimes resulting in loot several tiers higher than expected. For example, Elder Irudad may spawn with tier 8 zetachrome pumps in Joppa at the start of the game, even though Joppa has a very low zone tier.

Creature Tier

Creature tier is based on level and can be given as follows:

${\text{Tier}}={\text{Floor}}({\frac {Level}{5}}){\text{, min 1}}$

Note that this creature tier varies slightly from the tiering used to calculate XP, which can go as low as Tier 0. Refer to the Experience page for more information about XP tiers.

Item Tier

Item tier is manually specified for each item in the game's ObjectBlueprints.xml. You can view the tier of a particular item on its wiki page. For example, a flamethrower is a tier 4 item.

Surface Zone Tier

The subject of this section has no official name presented in-game. As a result, a name for it was chosen at the discretion of wiki editors.

The following map shows the zone tier for all surface areas in Caves of Qud.

Underground Zone Tier

To determine the zone tier for an underground zone:^[2]

If the current zone is 6 strata or deeper underground:
1. Calculate 2 + Floor((Strata - 6) / 5).
2. Modify the result to ensure it is a number between 1 and 8. The result is always constrained to the nearest number within the 1 to 8 range.
Otherwise, for any zone higher than 6 strata underground:
1. Take the surface zone tier at the location.
2. Modify that value to ensure it is a number between 1 and 8. The result is always constrained to the nearest number within the 1 to 8 range.

Zone tier exceptions

Certain biomes and zones override the underground zone tier rules. See individual articles for details:

Effects of Zone Tier

historic site locations^[3]
The XP reward for visiting a new historic site if you don't have a quest to visit that site (250 * static zone tier)^[4]
The XP reward for visiting a new village^[5]
The randomly-selected zone location for Kindrish^[6]
The tier of the randomly-selected creature when either/or atomizes into a random creature^[7]
The minimum tier for sparking baetyl rewards^[8]
Certain aspects of random faction encounters.^[9] This includes any of the following faction groups that appear with a legendary leader: Pariahs, Bears, Arachnids, Tortoises, Antelopes, Apes, Barathrumites, Birds, Mechanimists, Seekers of the Sightless Way, and Putus Templar^[10]. Some, but not all, of these factions use zone tier to determine certain features of their encounter. For example, legendary Barathrumite faction leaders will carry scrap and junk appropriate to the static zone tier.
The level and quantity of cybernetics credit wedges rewarded in the relic chest at the bottom of a historic site^[11]
A small number of legendary creature zone spawns (legendary baboons, snapjaws, glow-wights, eyeless king crabs, and goatfolk) and minor zone generation features.^[12]
The generation of relic items.
Turret generation of dynamic turret tinkers.^[13]^[14]

General Technical Notes

The following fields and methods return a "zone tier" value based on the "RegionTier" tag on the World Map terrain object and a few overrides, and are used for most applications of the tier system:

XRL.World.ZoneManager.zoneGenerationContextTier
XRL.World.Zone.NewTier

Those fields and methods apply the overrides discussed in Zoning Exceptions:

WorldTerrain.xml, feature Tier
XRL.World.ZoneManager.GetZoneProperty(), property "ZoneTierOverride"

The following methods utilize a “zone tier” value directly based on the “RegionTier” tag on the World Map terrain object without applying overrides:

XRL.World.ZoneManager.GetZoneTier()
XRL.World.WorldBuilders.JoppaWorldBuilder.getLocationOfTier(int)
XRL.World.WorldBuilders.JoppaWorldBuilder.getLocationOfTier(int, int)
XRL.World.WorldBuilders.JoppaWorldBuilder.getLocationWithinNFromTerrainTypeTier()

These methods are used for placing surface locations and village quests and historic site discovery XP; since no existing zone tier overrides apply to surface locations, not applying overrides here doesn’t change the game’s behavior.

Procedural generation is also influenced by other factors, such as the terrain type of the current zone and whether or not the current zone is part of a village or a unique location.
 Zone tier is determined based on a combination of the following elements:
 * The surface tier of the current [[world map]] {{parasang}}.
 * The depth of the current zone, if it is underground.
-== Background ==
-For historical reasons, the game uses two different systems to calculate zone tier. This can sometimes make determining the zone tier a bit tricky, because depending on which feature is using the zone tier, it may be calculated using one system or the other (even in the same single zone). For the purposes of this article, we'll give a name to each of those systems to help better distinguish them:
-* '''Regional Zone Tier:''' This type of zone tier is the most commonly used. It is closely linked to the world map terrain type of the zone. For example, all {{favilink|Hills}} areas have a '''regional zone tier''' of 2, even the few '''Hills''' parasangs that are in the far upper-right corner of the world map, sandwiched between the Deathlands and the Mountains.
-* '''Static Zone Tier:''' This type of zone tier appears to generally be an older type of zone tier system. It is based on static values that are defined in a configuration file<ref><code>Text.txt</code></ref> in the game directory. This system of zone tiers is used for fewer things, but it is still used frequently enough to be worth mentioning.
-As a general rule, these two zone tier systems tend to be quite similar on the western half of the world map. They differ more significantly on the eastern half of the map.

 For example, in an area with a zone tier of 5, tier 5 creatures (such as {{favilink|dynamic turret tinker|plural}}) and tier 5 items (such as {{favilink|fullerite gauntlets}}) are more likely to be found.

 === Creature Tier ===
-Creature tier is based on level. Creatures of levels 1-9 are tier 1 for the purposes of dynamic zone generation. A creature's tier increases by one for additional each five levels (creatures of levels 10-14 are tier 2, creatures of level 15-19 are tier 3, etcetera).

 === General Technical Notes ===
-The following fields and methods return a "regional zone tier" value, based on the "RegionTier" tag on the World Map terrain object. These are the most commonly used methods in the codebase for obtaining zone tier:
+The following fields and methods return a "zone tier" value based on the "RegionTier" tag on the World Map terrain object and a few overrides, and are used for most applications of the tier system:
-* <code>XRL.World.Zone.Tier</code>
-* <code>XRL.World.ZoneManager.GetZoneTier()</code>
 * <code>XRL.World.ZoneManager.zoneGenerationContextTier</code>
+* <code>XRL.World.Zone.NewTier </code>
+Those fields and methods apply the overrides discussed in Zoning Exceptions:
+*<code>WorldTerrain.xml, feature Tier</code>
+*<code>XRL.World.ZoneManager.GetZoneProperty(), property "ZoneTierOverride"</code>
-The following fields and methods return a "static zone tier" that is instead loaded from the game's <code>Text.txt</code> file.
+The following methods utilize a “zone tier” value directly based on the “RegionTier” tag on the World Map terrain object without applying overrides:
+* <code>XRL.World.ZoneManager.GetZoneTier()</code>
 * <code>XRL.World.WorldBuilders.JoppaWorldBuilder.getLocationOfTier(int)</code>
 * <code>XRL.World.WorldBuilders.JoppaWorldBuilder.getLocationOfTier(int, int)</code>
 * <code>XRL.World.WorldBuilders.JoppaWorldBuilder.getLocationWithinNFromTerrainTypeTier()</code>
-* <code>XRL.World.Zone.NewTier</code>: This is one of the most widely used for "static zone tier" and is the only method that takes z-level into account. It has peculiar logic for calculating below-ground tiers, which completely ignores the surface tier at strata 6 and below.
-* <code>XRL.ZoneTemplateNode.VariableReplace()</code>
+These methods are used for placing surface locations and village quests and historic site discovery XP; since no existing zone tier overrides apply to surface locations, not applying overrides here doesn’t change the game’s behavior.
