The A-DSD advanced dwarf spider droid represented an enhanced iteration of both the DSD1 dwarf spider droid and the heavy dwarf spider droid, boasting increased firepower and stronger defenses, along with the ability to function in total darkness.
Sev characterized its speed as being less than that of a Gungan tree sloth.
Engineered by Commerce Guild Manufacturers, the primary purpose of this droid was to locate and eliminate miners who were non-compliant with the trade conglomerate's tariff obligations. It was available on the open market for a considerable duration prior to the Battle of Geonosis. Furthermore, it found application within holographic training programs designed for clone troopers stationed on Kamino. However, its mass production was delayed until after the activation of the droid armies because of excessive costs.
