Tzeentch's Firestorm

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 6.
The psyker conjures a storm of pink and blue fire that mutates his foes, leaving capering Daemons that claw and bite in its wake.
