Description
All items in Wurm have a base value which depends on the item type and the effective item quality. The base value is used for:
- the Get price,
- favor gain when sacrificing at an altar.
Get price
The Get price of an item can be determined by right clicking an item in the inventory and selecting Prices > Get price. The result is a message in the event log:
A trader would sell this for about 23 copper and 31 iron.
- A message giving roughly the amount of favor from sacrificing is given as well
This message is misleading because a trader has flexible prices and usually sells and buys at a much higher rate.
The Get price of an item can be calculated with the formula:
- Get price = c * QL²
c is a item type dependent constant which is listed in the table below. c can be calculated from a Get price with the formula
- c = Get price / QL²
A rough estimate of the Get price can be calculated from the tenth of the quality level:
- Get price = c2 * (QL/10)² with c2 = c * 100
Favor
Priests can gain favor for sacrificing items in an altar. The amount of favor awarded is 1 favor per 500 irons sacrificed.
The amount of favor can be calculated with the formula:
- favor = c * QL² * ( 1/500i ) which is equivalent to favor = c * QL² * 0.002
A variant of that formula is:
- favor = cf * (QL/10)²
The table below lists the constant cf which is calculated as:
- cf = c / 5i
Note: Magranon priests get twice the favor from sacrificing metal items, while Vynora priests get twice the favor from sacrificing wooden items, and Fo priests get twice the favor from cloth items.
Item type constants
The following table lists the item type constants for some items. The constants can be used with those formulas:
- Get price (irons) = c * QL²
- Favor = c * QL² * 0.002
- Get price (irons) = c2 * (QL/10)²
- Favor = cf * (QL/10)²

History for constants and formula
The constant c and get price formula c * QL² are used by the server.
The constant cf and favor formula cf * (QL/10)² originated from combining three parts: the get price fromula c * QL², a copper per irons conversion 1c/100i and a favor per coppers conversion 1f/5c. Combining these reduced the number of zeros one must work with. Consequently, the formula for calculating favor can be done mentally with ease.
The constant c2 and get price formula c2 * (QL/10)² originated form trying to make the (QL/10)² work for calculating get price in irons. Essentially formula and constant convert get price formula c * QL² to coppers and then multiplies c by 100 to arrive at irons.
