Undying Servitue

Undying Servitude has a casting value of 7 and a
range of 12". If successfully cast, pick 1 enemy
Hero with a Wounds Characteristic of 6 or less
within range and visible to the caster. That unit suffers D3 mortal wounds. If that Hero is slain
by this spell, before removing that Hero from
play, you can add 1 Vampire Lord to your army.
Set up that unit within 3" of the slain Hero, and
then remove the slain Hero from play.
