Actually, according to the player's guide, it's a DC 20, DC 25 to make it Masterwork. I would recommend taking the 20, especially if you wanted to go Masterwork, which would cost (with 25% extra cost) 3,541 silver and 6 copper (so, 354 gold, 1 silver, 6 copper), all of which I can front, and if Ershin wishes to go 50% with me on that, that means both of us will pay 177 gold and 8 copper. If Ershin, Phantom, and the GM are all good with this, let's rock it?
