Desynthesis

Desynthesis is a general action available to Disciples of the Hand at level 30. It allows players to break items down to their original materials. To unlock this ability, visit Syntgoht in Ul'dah - Steps of Thal and complete the quest Gone to Pieces. Select an item and choose Desynthesis from its subcommands to begin the dismanteling process.

Desynthesis skill levels
Each disciple has its own desynthesis skill level. Improving that skill level improves chances at successfully taking apart an item. A high skill level also increases the chance of the desynthesis yielding a rare form of residual spiritbond energies known as demimateria. Failed desynthesis attempts may result in the skill dropping.

While desynthesis skills for each discipline are independent, there is a skill point maximum that applies to all disciplines combined. Each classes' maximum skill level is 380 and the combined skill level maximum is 1160. If a player is at the combined skill level maximum, any skill point gains in a class will take points from another class.

The desynthesis skill menu can be access by opening the Character window, going to the Classes/Jobs tab, and clicking on a Disciple of the Hand class in the list.
