Tzeentch's Firestorm

The psyker conjures a storm of pink and blue fire that mutates his foes, leaving capering Daemons that claw
and bite in its wake.
Tzeentch's Firestorm has a warp charge value of
7. If manifested, select an enemy unit that is
within 18" of the psyker and visible to him. Roll
9 dice; the enemy unit you selected suffers a
mortal wound for each roll of a 6.
