attrition

[majdavlk]

there is upper limit to attrition right?
on the wiki it says so, but i have never been able to test that ingame.

on the wiki it says that the attrition is proportionally higher the higher youre over supply limit, if this is true, what is the formula for attrition ?

are attrition modifiers additive or multiplicative?
could i avoid attrition if i had 400 martial commander on my centre flank?

also how does the game decide which units desert first? is it random? is it proportional to the amount of units of that type? do "richer" units die the least? (HC HI)

If i have 1000 light infantry and 1000 heavy cavalry at 1% attrition will i loose 10 LI and 10 HC ?

i've found this on the wiki ( https://ck2.paradoxwikis.com/Attrition )

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.

so i guess the upper limit would be something like 40% of total troop count in an epidemic mountain range during severe winter.
