Workbench

A Workbench is a tool used by the Armorsmithing, Artificing, Runecrafting, Weaponsmithing and Foraging professions.

You can find a workbench in Kelari Refuge in Freemarch and the Manufactory wing of Meridian, which is located on the left side of Meridian.

Using a workbench implies either right clicking it, or, opening your professions window and start crafting the items you desire. In order for this to work properly, you need to be standing close to a Workbench.
