Inkbombs were explosives that released a cloud of ink. They were used in aquatic environments in order to blind and confuse enemies. During the Second Imperial Civil War, Imperial Knight Treis Sinde used inkbombs to attack a squad of seatroopers. With a cloud of ink obscuring the seatroopers' vision, they were forced to switch to infra-red sensors, allowing Sinde to ambush them as they made the switch.
