If I have multiple abilities that each state "Items made with/from X are always masterwork; the masterwork cost is included in the price of X.", should I reduce the cost of each ability by the masterwork price, or just leave the prices alone? My (maybe wrong) thinking is that, since each items is already masterwork, you shouldn't need to "pay" for the masterwork cost from the other items, though I may be just splitting hairs here. Thanks in advance for any info.
