Attrition.png Attrition happens when the number of troops in a province is higher than the supply limit of that province.

补给上限

每个省份的补给上限取决于地形和各种修正。

补给上限修正 :

  • 基础补给 为5K。
  • 地形补给 平原和田地为5k, 草原为4k,树林和丘陵为3K, 山地和热带雨林为2K,极地和沙漠为1K。
  • 疾病惩罚 每种传染性疾病降低4k补给。
  • 冬季惩罚 当省份处于冬季时,补给上限-3k(温和),-4k(正常),-5k(严酷)。
    • 省份的冬季有多糟糕由它们的气候决定。
    • 冬季一般始于10月终于3月(极地地区6月), 严酷的冬季也可以在3月或5月变为温和的冬季。

百分比修正 :

  • 沿海省份: +50%
  • 省份地产
    • 拥有的 地产:每个地产+50%
    • 被占领的地产: 每个地产+25%
    • 中立地产: 每个地产+25% (同宗教组, 并且既没被己方劫掠,也不处于战争中)
    • 敌对地产: 每个地产-10%(异宗教组, 并且既没被己方劫掠,也不处于战争中)
  • 控制临近地产: 最多+75%
    • 只能类加在拥有或控制的地产直到总数达到+75%。
    • 占有地产也被计入到控制临近地产上, 所以您也可以利用此在敌方境内建立一个补给线。
  • 科技来自首都军事组织科技的加成,每级 +12.5%,最多 +100%.
  • 原始宗教故土: *0.12, 如果改省份宗教为未改革原始宗教并且它的领主也是同原始宗教。
    • 如果军事组织4在您的首都研究完成了,该减成失效。
    • 未改革原始宗教军队也不会受原始宗教故土惩罚。
    • 改革原始宗教可以在它的未改革领土上免受此惩罚,但对于其他的原始宗教,惩罚仍生效。 有Holy Fury.png, 改革宗教有 不屈 教义可以免受损耗惩罚。
    • 长生天和阿兹特克多神教没有此修正, 阿兹特克多神教不会增加在其他原始宗教地区的损耗, 长生天攻击者可以无视损耗。有Holy Fury.png, 改革的长生天必须拥有 不屈Eternal Riders 教义来无视此损耗

补给上限至少可以维持1000士兵。 (如果该省份处于大型流行病期间或有"公路抢匪" 省份修正)

Use of supply

All non-shattered units in a province use supply. Thus, neutral and friendly units can cause your units to take attrition. Giving ally orders can reduce the risk of friendly units contributing to exceeding the supply limit.

If you have a unit selected, province tooltips are updated to include "Total troops when our armies arrive".

Monthly attrition (over supply limit)

If an army exceeds the supply limit of a province, a percentage of troops will die every month due to attrition:

  • Base land attrition: 5%
  • Terrain modifier: +2.5% for forests and hills. +10% for mountains, arctic, and deserts
  • Epidemic disease: +5%
  • Winter: 10% if mild, 15% if normal, 20% if severe
  • Army leader: -0.1% x martial skill of army's centre commander.

The value above represents a maximum attrition that can occur. However, if the percentage of troops over the supply limit is low, only a portion of the maximum attrition will occur.

Monthly attrition (out of supplies)

Armies begin suffering minor attrition when they are no longer in or adjacent to their realm. The monthly percentage becomes more severe the longer they have been out of supply. This makes it dangerous to attack a distant enemy if you must march over neutral or hostile land.

Armies aboard ships do not suffer attrition, but time aboard ships is considered time out of supply. This reduces the effectiveness of unloading ships onto neutral lands to prevent the need to have an amphibious assault battle.

You are always in supply within your own realm, even when attacking a fellow vassal. Occupying a holding extends supply to neighboring provinces. Armies besieging a holding are also supplied if there is free loot available in the province; this free loot will be slowly depleted even if the army is not raiding.

Nomadic horde troops are not affected by "out of supply" attrition; this is to compliment certain nomadic CBs which can target non-bordering realms.
