Wear
v50.14 · v0.47.05 This article is about the current version of DF.Note that some content may still need to be updated. |
Wear is the degradation of materials over time, primarily in the context of clothing. Wear will alter the value of an item, and is denoted by the symbols x, X and XX. For example, over time a dwarf's "Pig tail shirt" will degrade into a "xPig tail shirtx", a "XPig tail shirtX" and eventually a "XXPig tail shirtXX" before disappearing entirely. Every 806400 "points" of wear will increase the item's damage level one step (i.e. "item" -> "xitemx" -> "XitemX" -> "XXitemXX" -> destroyed). If you sell worn clothes to caravans early enough they are still worth good money:
| Wear Level | Remaining Value |
|---|---|
| xItemx | 75% |
| XItemX | 50% |
| XXItemXX | 25% |
Animal-based products can rot, which is different from wear (see miasma). Crops and harvested plants can wither if not stored in a stockpile, making them useless but generating no miasma.
Notes on wear:
- Clothing that is being worn will wear out, over time, due to normal usage. This happens regardless of material.
- Armor does not wear out, unless it's kept in a refuse stockpile.
- All clothing and armor in a refuse stockpile will wear out. This is intended as a means of destroying old used clothing that would otherwise make dwarves grumpy. Note that a stockpile with any type of refuse enabled (such as bone) counts as a refuse stockpile for wear application.
- Items (including clothing, leather, and wood) suffer accelerated wear while on fire (10 points of "wear" every game tick; a burning item will be totally consumed after exactly 322560 game ticks (which, at 1200 ticks per day, takes 9 months and 16.8 days)).
- Items suffer accelerated wear when their temperature exceeds their base material's HEATDAM_POINT (common with burning organics).
- Items suffer accelerated wear when their temperature falls below their base material's COLDDAM_POINT (such as wood and cloth items stored aboveground in a trade depot or starting wagon in a glacier biome). Walls do not halt this effect.
- Building destroyers cause wear on certain types of furniture (such as doors and hatch covers) until they are completely destroyed.
- Clothing worn by invaders is also subject to wear.
- Cages do not prevent wear.
- All improvable items made from creature or plant materials (e.g. cloth, silk, leather, yarn, or wood) will gradually wear out over a very long period of time, even if just sitting in stockpiles, gaining one level of wear every 100 years.
- All items which are on fire take 10 points of "wear" every game tick, and every 806400 "points" of wear will increase the item's damage level (i.e. "item" -> "xitemx" -> "XitemX" -> "XXitemXX" -> destroyed); as such, a burning item will be totally consumed after exactly 322560 game ticks (which, at 1200 ticks per day, takes 9 months and 16.8 days) unless the item takes additional damage from other sources (such as exceeding its HEATDAM_POINT, which is what usually happens with wood and other organic materials, or being attacked by a building destroyer).
- Artifacts never burn away, because their artifact status locks their "wear" level at zero.
