Deterioration Rate

Deterioration Rate is a stat: The rate at which this item deteriorates when left outside, in average hit points per day.

Deterioration rate is also affected by things like weather, roofs, toxic fallout, or being left in shallow water. Its minimum allowed value is 0 / day. Its default value is 0 / day.

Factors

The following factors are applied to base deterioration rate in order of appearance. Genepacks exclusively do not deteriorate from environmental effects, which is likely to account for their constant deterioration rate when outside of gene banks .

Quality

For items that have quality:

Quality	Factor
Awful	×200%
Poor	×150%
Normal	×100%
Good	×80%
Excellent	×60%
Masterwork	×30%
Legendary	×10%

Protected: x0%

Pollution

Applies to items that deteriorate from environmental effects within polluted cells.

Multiplier for pollution: x150%

Noxious Haze

Applies to unroofed items that deteriorate from environmental effects when the Acidic smog game condition is active and when toxic fallout is not, which suppresses its effects. This means that deterioration rate can only be affected by one or the other at a time, not both.

Multiplier for acidic smog: x300%

Toxic Fallout

Applies to unroofed items that deteriorate from environmental effects when the Toxic fallout game condition is active.

Multiplier for toxic fallout: x300%

Near Harbinger Tree

Applies to items being consumed by a harbinger tree.

Multiplier for harbinger tree: x200%

Shambler Corpse

Applies to corpses with the shambler corpse hediff.

Multiplier for shambler corpse: x500%

Calculating Deterioration Rate

All of these factors combined result in:

Final Deterioration Rate = (Base Deterioration Rate + Unroofed + Outdoors + In Water) × Rain Rate × Protected × exposed to Pollution × exposed to Acidic smog or Toxic fallout × being consumed by a Harbinger tree × is a Shambler corpse

Which results in an effective maximum of:

Final Deterioration Rate = (Base Deterioration Rate + 0.5 + 0.5 + 3) × 5 × 1.5 × 3 × 2 × 5

Final Deterioration Rate = (Base Deterioration Rate + 4) × 225
