Roll a D6 for every enemy unit on the table (even it in combat). On a roll of 4+ the unit suffers a wound with no armour saves allowed. Also, a new Spirit Host unit is created within 12" of the Vampire, at least 1" from the enemy, with a number of Wounds equal to the number of Wounds inflicted by the spell. For example, if the Wind of Undeath inflicts 7 Wounds, the Spirit Host unit created consists of two bases, with a total of 7 Wounds.
