Shem's Burning Gaze is a magic missile with a range of 24" and causes D6 Strength 4 hits (which count as Flaming Attacks). Against models with the Daemonic, Undead or Vampiric special rules, this is increased to 2D6 Hits. The Wizard can choose to extend the range of this spell to 48" and increase the Strength from 4 to 6. If they do so, the casting value is increased to 12+.
