Dyeing also has a quality level, as does Decorating/Encrusting (with gems, leathers, cloth, etc). Prepared foods have quality levels. Alcohol has a hidden quality rating that controls the amount of happiness a dwarf gets from drinking it. It is not yet known whether the damage or destruction of masterful alcohol can cause tantrums. |

Artifacts, like masterpiece items, will cause a significant mood drop in the creator when destroyed or stolen. According to inspections of the memory values, it seems that artifacts have the same quality value as masterpiece items. It is unclear if this is true for weapons/armor or not - opinions differ as to whether artifact weapons and armor have a 2.0 multiplier or something higher; nothing has been found in the game code to support such, but observation suggests otherwise. |
