The Poisoned Chalice is a splinter warband of the Death Guard Traitor Legion. The Poisoned Chalice are led by deranged groups of Foul Blightspawn and Putrifiers. Rampaging across the galaxy with zealous vigour, they obsessively seek vile ingredients and hapless test subjects, questing to brew the perfect plague.
- The Great Brewing (Unknown Date.M42) - Deep within the Imperium Nihilus, the Poisoned Chalice invade the medicae world of Pelucil. They seek to use the planet's macro-alembic complexes to brew the ultimate plague in Nurgle's name.
The Poisoned Chalice's Power Armour is the same as that of the Death Guard, composed of decayed and cracked plates of ceramite in dark green with black trim. The Poisoned Chalice's Chaos Space Marines, like those of the Death Guard, often wear grotesquely warped suits of antique Mark III Iron Power Armour.
The Poisoned Chalice's warband badge is usually a modified version of the standard Mark of Nurgle, similar to that used by the rest of the Death Guard.
