Treis Sinde throwing an inkbomb. Inkbombs functioned as explosives that, upon detonation, created a dispersing cloud of ink. These devices found their utility in underwater or aquatic combat scenarios, where they served to disorient and visually impair adversaries. A notable instance of their usage occurred during the Second Imperial Civil War, when Imperial Knight Treis Sinde deployed inkbombs as part of an assault against a squad of seatroopers. The resulting ink cloud compromised the seatroopers' visual acuity, compelling them to rely on infra-red sensors; this tactical shift created an opportunity for Sinde to execute a successful ambush while they were reconfiguring their sensory input.
