Fireblast

A Fireblast spell engulfs the target in coruscating
flames from which capering daemons spring forth.
Pick a visible enemy unit within 18" of the caster.
The unit you pick suffers D6 mortal wounds.
After the damage has been inflicted, you can set
up a unit of Pink, Blue or Brimstone Horrors
within 1" of the target; the number of models
set up in the new unit is equal to the number of
mortal wounds inflicted.
