Plague Squall

Singing an extravagant prayer to Grandfather Nurgle,
the Sorcerer causes the skies to split open like the
swollen belly of a corpse.
Roll 7 dice. For each roll of 6, you can pick an
enemy unit that is visible to the caster. That
unit suffers D3 mortal wounds. If you roll more
than one 6, you must pick a different enemy
unit to suffer each set of mortal wounds.
