The materials required depend on the quality and item level of the desired product. Higher quality items will also need a Plan before they can be crafted and the artisan upgraded to a certain level. Crafting also refers to all other services provided by Blacksmith, Mystic and Jeweler. Gems of higher quality also need to be crafted manually. As of patch 2.2.0, items may be crafted all at once, instead of the old 'one at a time' system.
