Barter System Formula

Buying price = (Item Value * fBarterBuyBase) + (Item Value * Skill * fBarterBuyMult / 100)

Selling price = (Item Value * fBarterSellBase) + (Item Value * Skill * fBarterSellMult / 100)

Item Value is a parameter of the item and can be viewed and edited in G.E.C.K.

Skill is Player's Barter skill. Although most merchants have a high Barter skill it has no effect on the process.

Note that the buying price can't be lower than the Item Value as well as the selling price can't be higher than the Item Value.
