Increasing mercantile skill and personality attribute cause lowering of selling price
When increasing the mercantile skill or the personality attribute, selling prices are going down instead of up, so a more mercantile character sells junk to traders cheaper than an less mercantile one. This can be easily tested with "fortify skill", "drain skill", "fortify attribute" and "drain attribute" spell on self. Or one can start a two games with mercantile in misc and major skills and try ro sell the same silver plate to Arille - the one with higher mercantile will gain less coins than the one with lower. Should be exactly opposite, right? Also, skill and attribute fortifications above 100 points are taking no effect on buying and selling prices, so do not try to test this behavior trying to fortify mercantile on character with 100 mercantile. Please stay in 0..100 brackets.
