Bavo Six
this truth serum was developed decades before the battle of Yavin, but was one of the primary sera used by the Empire in its IT-0 interrogation droids. It was usually administered with a greatly-enlarged needle, to increase the fear of the prison and make the serum work better and faster. It was a compound of regvis and bospridium, with trace elements in the composition R7Bo3Kr2. It induced paranoia and visual exaggeration, causing the victim to become afraid of everything.
