A stun charge represented an electrical discharge originating from a shock-filament. Should an individual make contact with a shock-filament, they would experience a potent electrical surge, strong enough to penetrate all types of footwear, regardless of insulation, and affect the person. The electrical surge was of such magnitude that it could knock out a Wookiee, and consistent exposure could prove fatal to a Human.
Xufal D'uat modified cells aboard his vessel, the Venom Sting, by integrating shock-filaments capable of delivering stun charges to those imprisoned within. This particular modification proved appealing to subsequent possessors of the starship, specifically a group identified as Thalassian slavers.
