Characters in One Piece are endlessly varied, and craftsmen are no less valued than fighters. While high-quality weapons and ships cost fragments, players who are skilled craftsmen can craft them without having to pay fragments.
Crafted items are classified as DISTINCT or NOVELTY.
Distinct creations basic items that the craftsman has spent time to craft, but they are not significant enough to be considered novelties. There is no limit to the number of distinct creations that a craftsman can create.
Distinct creations cannot be given to or used by other players.
Novelty creations hold significant importance to a character or a story arc. A novelty creation is one that the craftsman has poured blood, sweat, and tears into its creation. The item has achieved feats that have made both the item and its craftsman achieve renown in the world. Each character is only allowed to create 5 novelty items in their lifetime.
Novelty creations can be given to or used by other players.
