Digital weapons, or digi-weapons, are miniaturized weapons, often concealed in rings or other jewelry. Though miniaturized, they are capable of replicating the punch of full-sized weapons such as laspistols, hellpistols, needle pistols, hand flamers, and Inferno pistols. They can only be fired once and reloading is extremely difficult.

The technology required to manufacture digi-weapons is beyond the capabilities of the Imperium. Digi-weapons can only be created by the Jokaero species. Accordingly, they are very rare and almost impossible to buy. Their possession is normally restricted to the extremely wealthy or influential; they are more commonly used by Inquisitors.
