When a Daemon casts a spell from the Lore of Nurgle that causes one or more unsaved Wounds, choose a friendly Daemon of Nurgle unit within 12" of the caster, and roll a D6 for each Wound caused. For each result of 5+, add 1 Wound's worth of models to the unit. Models are added, one at a time, to the back rank. If the back rank is full at any point, or the unit has a single rank of at least five models, the next model starts a new back rank. Models that cannot be placed (because there isn't enough room, or you do not have sufficient models) are lost. Models created in this way have no upgrades and don't award additional victory points.

Stream of Corruption is a direct damage spell. The caster makes a Breath Weapon Attack. This may be cast in close combat, following the normal rules for Breath Weapons. All models Hit must pass a Toughness test or suffer a Wound with the Ignores Armour Saves special rule.

Miasma of Pestilence is an augment spell with a range of 18". Until the start of the caster's next Magic phase, all enemy units in base contact with the target unit reduce their Weapon Skill and Initiative by 1 (to a minimum of 1). The Wizard can choose to cast a more powerful version of this spell that instead reduces the Weapon Skill and Initiative of all enemy units in base contact with the target unit by D3 (roll once and apply the result to all affected enemies). If they do so, the casting value is increased to 10+.

Blades of Putrefaction is an augment spell with a range of 12". The target unit's close combat attacks gain the Poisoned Attacks special rule until the start of the caster's next Magic phase. If a model targeted by this spell already has Poisoned Attacks, its Attacks Wound the target automatically on a To Hit roll of 6.

Curse of the Leper can be cast on any unit (friend or foe) within 18". If cast on a friendly unit, Curse of the Leper is an augment spell that increases the target unit's Toughness by D3 (to a maximum of 10) until the start of the caster's next Magic phase. If Curse of the Leper is cast on an enemy unit, it is a hex spell that reduces the target unit's Toughness by D3 (to a minimum of 1) until the start of the caster's next Magic phase. The Wizard can choose to extend the range of this spell to 36". If they do so, the casting value is increased to 13+.

Rancid Visitations is a magic missile with a range of 18" that inflicts D6 Strength 5 hits. The target unit must then immediately pass a Toughness test or suffer a further D6 Strength 5 hits. The target must keep testing its Toughness in this manner until a test is passed, or the target is removed as a casualty.

Fleshy Abundance is an augment spell with a range of 18". Until the start of the caster's next Magic phase, the target has the Regeneration (5+) special rule (to a maximum of a 3+ save for Daemons of Nurgle).* The Wizard can choose to extend the range of this spell to 36". If they do so, the casting value is increased to 14+.

*(Warrior of Chaos only) If the target already has the Regeneration special rule, it instead gains +1 to all Regeneration saving throws (to a maximum of 2+) until the start of the caster's next Magic phase.

Remains in play. Plague Wind is a magical vortex that uses the small round template. Once the template is placed, the player then nominates the direction in which the Plague Wind will move. To determine how many inches the template moves, roll an artillery dice and multiply the result by the caster's Wizard level. If the result on the artillery dice is a misfire, centre the template on the caster instead and roll a scatter dice; the template moves a number of inches equal to the caster's Wizard level, in the direction shown by the scatter dice (if you roll a Hit!, the template remains where it is). Any model touched by the template must pass a Toughness test or suffer a single automatic Wound, with the Ignores Armour Saves special rule.

In subsequent turns, the Plague Wind travels in a random direction and moves a number of inches equal to the roll of an artillery dice (if a misfire is rolled, the Plague Wind dissipates and is removed). The Wizard can infuse Plague Wind with more power, so that it uses the large round template instead. If they do so, the casting value is increased to 25+.
