Invocation of Nehek is an augment spell that targets all friendly Undead units within 6". The target units immediately regain a number of Wounds as follows: Infantry gain D6 plus the caster's Wizard level in Wounds (roll for each unit), other troop types targeted gain 1 plus the caster's Wizard level in Wounds. However, models with the Vampiric, Ethereal or Large Target special rules can never regain more than 1 Wound per successful casting. Wounds gained are distributed as described in Resurrecting Fallen Warriors. The Wizard can choose to target all friendly Undead units within 12". If he does so, the casting value is increased to 12+. Alternatively, he can choose to target all friendly Undead units within 18". If he does so, the casting value is increased to 18+.
