Codex: Chaos Daemons (2016), p122 — Rotswarm

Bounding and buzzing, flopping and flapping, the bestial Daemons of Nurgle lurch awkwardly to war. They are herded by a Herald of Nurgle bearing the dubious title of Mouldsire of the Rotswarm, whose task is far from an enviable one. While they can impale a man with every proboscis stab, Plague Drones are spiteful, wilful Daemons that wish only to hurt other living things. The Beasts of Nurgle are all but impossible to herd, being lolloping simpletons whose joy at the sight of new playmates deafens them to even the most desperately bellowed commands. Despite these challenges, when the Mouldsire succeeds in herding the Rotswarm into the enemy's ranks the Daemons become a foul wall of corrosive slime and crushing bodies that swiftly reduces its victims to bubbling corpse-sludge.

Formation

• 1 Herald of Nurgle
• 7 units chosen in any combination from the following list:
  • Plague Drones of Nurgle
  • Beasts of Nurgle

Restrictions: None.

Special Rules

Harbinger of Nurgle: If the Herald of Nurgle from this Formation is a Lesser Locus of Virulence, Greater Locus of Fecundity or an Exalted Locus of Contagion, the special rules associated with that locus affect all units from this Formation that are within 12" of him. If such a unit is also affected by another locus, they will receive both benefits.

Corrosive Slime: All units in a Rotswarm have the Hammer of Wrath special rule, and these attacks have the Poisoned (4+) special rule.

Dubious Command: At the start of each of the controlling player's Assault phases, the Herald of Nurgle from a Rotswarm can attempt to direct a single unit from his Formation that is within 12" of him. To do so, he must take a Leadership test. If the test is passed, the directed unit can re-roll failed charge rolls and all models in the unit can make 3 additional Attacks until the end of the turn; if the test is failed, the directed unit must attempt to charge the nearest enemy unit in this Charge subphase, but is otherwise unaffected.
