40d:Item value

Value is determined by the base value of the object with multipliers for the material it is made out of, the quality of its creation, and any decorations on it.

The final value of an item multiplies the base value of the form of the object (a stone, a statue) by the material multiplier (granite, gold), and by the quality modifier (fine, masterful) if any, and then adding any final value for decorations.

Rooms also have a "value" which determines their quality, which is the sum of the objects placed within their designated area plus the materials that surround it plus improvements (such as engraving) to those materials. See room for a more complete discussion of these values, and How do I increase the value of a room for a complete list of options.

Base values of items

The base value of an item is found from what the item is, not what it is made out of. For example, a wood block uses the base value for a block, not the one for 'wooden'. A wood log uses the base value for raw material.

Material multipliers

The material multiplier of an item is found from what it is made out of. For example, a wood block uses the same multiplier as a log or chest - that for wood. Oddly, burned wood is no longer considered wooden, but has other modifiers.

Quality

Item value is further increased by applying the quality modifier.

Designation	Description	Value Modifier
Item Name	—	×1
-Item Name-	Well-crafted	×2
+Item Name+	Finely-crafted	×3
Item Name	Superior quality	×4
≡Item Name≡	Exceptional	×5
☼Item Name☼	Masterful	×12
Unique Name	Artifact	×120

Decorations

Your craftsdwarves can add decorations to your objects. This increases their value. The base value of a decoration is 10. This is multiplied with the material the decoration is made of and the quality of the decoration, and added to the value of the item. For example, a gold stud would be worth 10 (base value for the decoration) times 30 (material multiplier for gold) =300☼. A finely crafted gold stud would be 3*10*30=900☼.

Engravings are decorations with the standard material modifiers.

Note that some races have additional modifiers that cause them to prefer certain types of decorations over others. For example, Dwarves prefer encircled bands and menacing spikes over hanging rings, while Elves perceive menacing spikes as completely worthless.

Dyeing

Value gained by dyeing is added, like that of decorations. Only thread, cloth and its products can be dyed. For details see Dye.
