Tools are part of the primary means of performing tasks. Each Character Class has a different set of tools and equipment associated with it. Tools are not currently physical items in the game, and are 'stored' in toolracks or around a monument. For the purposes of keeping micro-management simpler, tools are not managed by the player; they simply appear as needed.
The Dwarves of Glistenveld believe that tools should be blessed, and treated with great care. Consequently, they ensure they never leave any lying around, and always put them back where they belong.
