Haggle

Determining how much things is worth is a feature of this skill, but it's more used to get better prices on what goods are being sold. Typically all goods are sold to NPCs at half their buy value. So a 862 gp +1 sword would normally be sold for 431 gp. Some salesman will always haggle though to see if they can get a better deal. Once the total value of a lot is determined you can roll a haggle to see about getting a better price. Haggle is rolled against haggle and is most assuredly affected by disposition. When comparing haggle you subtract your opponent's roll from your roll and compare it to the chart below for price modifiers.

Roll Difference	Sell Price modifier
Lower than -16	15% value of goods
-15	25% Value of goods
-10	35% Value of goods
-5 to 5	50% value of goods
10	65% value of goods
15	75% value of goods
16+	85% value of goods

Haggling, of course, isn't limited to the selling of items to a merchant. The buying of goods and services can be haggled and negotiated too. Below is the chart used for procuring goods.

Roll Difference	Buy Price modifier
Lower than -26	115% value of goods
-20	110% Value of goods
-15	105% Value of goods
-8 to 8	100% value of goods
15	95% value of goods
20	90% value of goods
26+	85% value of goods
