The may be upgraded to make processes a percentage faster. The equation for a Crafting Item's new speed after a certain upgrade is Original_Time * (100 / (0.95 + Upgrade_No * 0.05)), with "Original_Time" referring to the Crafting Item's default processing time, and "Upgrade_No" referring to the level that the structure is at after the upgrade.

The can only be upgraded when the structure is idle. A random amount of crystals (a mix of Crystals, Polished Crystals and Carved Crystals, sometimes only one of a certain type) is required as well as coins. As the upgrade gets higher, the chances of getting a more expensive mix of Crystals is higher.
