Attrition causes armies to take casualties if they move through hostile terrain such as snowy wastes, deep ocean, deserts and swamps. Additionally, corruption and some other factors can cause attrition.
Overview[]
- Any
attritional effects present in an area on the campaign map can be seen on the tooltip shown when the cursor is held there. 
Vampire Coast and Vampire Counts (except The Barrow Legion) armies will suffer attritional casualties when moving through non-vampiric territories, and vice-versa.- Other factions have ways to mitigate or ignore attrition. High Elves can perform a rite to ignore attrition for 20 turns, while Tomb Kings simply ignore all attrition (the dead do not care).
- Encamp and Raiding stances as well as being garrisoned in a settlement (unless besieged) prevent most forms of attrition.
- Any faction that spreads corruption is immune to the attrition that the same type of corruption would cause otherwise.
- Factions that prefer certain climates are usually immune to related attrition (for example, Chaos-aligned factions aren't affected by Chaos Wastes attrition).
- Any form of attrition also prevents army replenishment, if it would otherwise be available (for example, in an owned province suffering from significant corruption).
- Terrain should not be confused with climate.
- Certain Nurgle plagues and Skaven's Pestilent Scheme Priest can cause attrition while a certain Tzeentch's ability can trigger corruption for a specific army for 5 turns.
- If a faction owns no settlements, their armies will start suffering from attrition, except Beastmen/Spirit of the Jungle/Rogue Armies.
In Total War: Warhammer III, attrition mechanics have changed significantly and only always only apply between turns, whereas previously terrain-based attrition would be applied instantly and constantly as an army moves through affected terrain. Therefore armies can now move through any such terrain without penalty, as long as they are able to end the turn outside of it. On the other hand, the amount of attrition suffered between turns is much more impactful compared to briefly moving through hostile terrain in previous games.
