The Massassi Ink Rifle was a crafted rifle weapon developed by the Massassi Sith that resided on the moon of Yavin, Yavin 4. Only a few examples of these weapons had survived into the era of the Galactic Civil War.
In appearance, they were a carved barrel which was mounted to a horn-shaped stock and was seemingly adapated to fit onto a scimitar. This allowed it to be used either as a long ranged rifle or as a melee weapon in close quarter combat. The ammunition consisted of a cartridge that was filled with a dark, viscous fluid which resembled ink but caused localized paralysis when it came into contact with flesh. Its effects were even more profound if the fluid struck the eyes of a target as it was capable of causing blindness.
