Djaf's Incantation of Cursed Blades is an augment spell with a range of 12". The target unit's close combat Attacks gain the Killing Blow ability until the start of your next Magic phase. If the target's unit Attacks already have the Killing Blow or Heroic Killing Blow ability, these will take effect on any To Wound rolls of a 5 or 6 whilst this spell is in play. The Wizard can choose to extend the range of this spell of 24". If he does so, the casting value is increased to 10+.
