Blacksmithing is the ancient art of working metal to make swords, armor, and (for the land lubbers out there) a plough or two. A pirate can take blacksmithing work at the Iron Mongers. Working the blacksmithing puzzle takes skill and planning. The goal of the puzzle is to clear all of the squares on the board by striking each one three times. However, the pattern on each square governs which squares may be struck next. It takes planning and forethought to complete the board without first running into a position where no further moves are legal.
