Final Fantasy XIV's crafting system is rich with detail, requiring a fair bit of knowledge from players in order to successfully craft items. Not everything is explained in the game from the start, however, giving players the chance to experiment and learn what works best for themselves. There was a prior developer dispatch regarding the crafting system, but the team at Square-Enix has just released a new FAQ detailing some of the more subtle variants of crafting. While it's not full of formulae to let players make the optimal crafting build, it certainly does shed a great deal of light on the previous unknowns for the system.
Most players had noticed sparks produced from their synthesis on more than one occasion, but up until now it wasn't clear what the sparks represented. Apparently, the aetherial sparks (as they are referred to in the dispatch) come from straining the materials, either by trying to work too fast or attempting to craft something outside of your skill range. The FAQ also covers elemental destabilization and the effects of various craft-related attributes, such as Control helping to avoid both destabilization and sparking. Final Fantasy XIV's burgeoning crafter population should take a look at the news, as it might mean the difference between a fresh suit of armor and a fresh set of botched crafts.
