A Heavy Blight Launcher is a type of heavy Grenade Launcher used by the forces of the Death Guard Traitor Legion. It is capable of firing three armour-piercing blight shells at a time drawn from a rusting drum magazine in rippling volleys. This rain of disease-ridden shells can reduce a battle tank to a corroded, collapsing wreck in moments, or bring whole squads of heavily armoured infantry to their knees.
