Reason: What does commerce have to do with book experience? also, this info is better on other pages.

Caves of Qud has a bartering system where items vary in price based on a multitude of factors. Commerce is the base value that is specified for each item that is then multiplied or divided by a multiplier depending on selling or buying.

Trading Multiplier Formula

${\text{Multiplier}}={\frac {0.07\times ({\text{Ego Modifier}}+2{\text{(if Snake Oiler)}})+0.35}{5({\text{if Socially Repugnant)}}}}$

If the player has Glotrot, Ego modifier and Snake oiler no longer have an effect and returns a flat -3. The equation then becomes

${\text{Multiplier}}={\frac {(0.07\times -3)+0.35}{5({\text{if Socially Repugnant)}}}}$

The multiplier cannot be higher than 0.95(achievable with +9 Ego modifier or +7 Ego modifier with Snake Oiler) and the multiplier cannot be lower than .05 (-5 Ego modifier or -2 Ego modifier with Socially Repugnant).

When buying an item from a trader, this multiplier is divided by the value of the item in question. When the item is sold, the value is multiplied by the multiplier.

Sacred Well Reputation Formula

Main article: Sacred well

How much reputation the Sacred well gives is also dependent on the commerce value of the object.

${\text{Reputation}}={\text{Commerce}}/10$

Reputation cannot go lower than 1, and if an object that has no specified value defaults to 10 reputation.

Book Experience Formula

${\text{Exp}}={\text{Floor}}({\frac {Commerce^{2}}{25}})$

Modifications and Commerce

Each modification has a Value attribute that is multiplied against the base Commerce value to get the new modified value.
