Synthesis is one way for characters to gain new items and equipment. Some of the classes are able to harvest materials in the wild, such as wood and plants. They can then use these materials to craft better items, and sometimes even equipment.
When they begin crafting, they must first select a recipe from the given list. From here, they can use skills to increase its durability, craft the item, or increase their crafting ability. Note that MP is replaced by CP, which is Crafting Points. Once this reaches zero, then they cannot craft anymore on that particular item. Players must complete the process before the item's durability reaches zero, and if done right, then the item will be made.
