The Carnifex is known as the Screamer Killer by warriors of the Imperium because of the high-pitched scream it makes as it rushes forward, scything its razor-edged killing arms. Its massive, rounded body is extremely tough, having a chitinous hide which protects it from damage and a shape that allows it to withstand tremendous pressures. A Carnifex is a living engine of destruction evolved for use in shock assaults, space ship boarding actions and massed battles where it can smash through almost any obstacle, whether it is a defensive line, enemy tanks or a fortified position. The assault of these creatures is terrifying to behold: a primeval and irresistible force which smashes men and vehicles aside like children’s toys. Carnifexes are armed with four great sickle-shaped claws of diamond hard chitin, bone and cartilage. The combined assault of these mighty scythes is powerful enough to rip even through amour plus and ceramite with ease. Carnifexes also have the capacity to energize a form of bio-plasma in their gut via rasping plates in their throats, the source of their high-pitched scream. An electrical field around the claws holds the incandescent plasma ball until it is launched at the target.

Weapons: Bonescythe: The Carnifex has 4 electrically charged scythes, one on each arm, but he counts as making a single ’pinch’ attack with all four. The damage and attack are aggregated as a single attack dealing 3d100 damage plus double his strength modifier. The Carnifex cannot multiweapon fight or otherwise separate the attacks made by individual bone scythes.

Weapons: Bioplasma: The Carnifex vomits forth this psychic acid. It has a range of 210 feet and can be targeted either at an opponent (using their AC dealing 2d12 damage with no reflex save on the target struck and splashing targets in a 10 foot radius) or against an area of the ground (DC 10) and splashing all targets. If splashed a targets get a Reflex save DC 15 to save half the damage.
