Each time a Wizard successfully casts an augment spell from the Lore of Nehekhara at a friendly, Undead unit, the target(s) of the spell immediately recovers D6+1 Wounds' worth of models, as described in Resurrecting Fallen Warriors. Chariots, Monstrous Infantry, Monstrous Cavalry, Monstrous Beasts can only recover D3 Wounds, and Monsters can only recover a single lost Wound in this way per spell.
