Haggling

This proficiency is useful to the thrifty adventurer.  By having skill in verbal manipulation, the player character can bargain down prices with merchants and dealers.  For each intensity in Haggling, the character may attempt to bargain down a set price by 5%.  To accomplish this, the character must match his Haggling check against the Willpower of the clerk.  If the match is successful, then the purchase price is lowered accordingly. The merchant will not, however, lower the retail price below actual unit cost (in other words, the merchant cannot be forced to lose money on the deal.)

Critical Success:  The merchant sells the item at unit cost.

Critical Failure: The shopkeeper is insulted and throws the adventurer out of the store or simply tries to sell the item at an increased price.
