Commerce

From Caves of Qud Wiki
Jump to: navigation, search

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[edit | edit source]

\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[edit | edit source]

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[edit | edit source]

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

Modifications and Commerce[edit | edit source]

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