When a Daemon casts a spell from the Lore of Nurgle that causes one or more unsaved wounds, choose a unit of Plaguebearers or Nurglings within 12" of the caster, and roll a D6 for each Wound caused. If it is a unit of Plaguebearers, add 1 model to the unit for each result of 5 or 6. If it is a unit of Nurglings, add 1 base to the unit for each result of 6. 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 do not award additional victory points.
