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.

${\displaystyle {\text{Multiplier}}=0.07\times ({\text{Ego Modifier}}+2{\text{(if Snake Oiler)}})+0.35}$

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

${\displaystyle {\text{Multiplier (with Glotrot)}}=0.14}$

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).

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

## Reputation Effect on Trade Prices

Reputation with the merchant also affects trade prices, acting essentially as a bonus or penalty to the player's ego modifier.

Reputation with merchant Bonus applied to Ego Modifier for Trade
600 or more +3 bonus
250 to 599 +1 bonus
-249 to 249 0
-599 to -250 -1 penalty
-600 or less -3 penalty

## 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.

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

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

## Book Experience Formula

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

## Modifications and Commerce

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