Merciless Blizzard

Merciless Blizzard a spell that has a casting value
of 12 and a range of 12". If successfully cast, pick
1 enemy unit within range and visible to the
caster. That unit suffers 4D6 mortal wounds,
but for each roll of 1, the caster also suffers D3
mortal wounds that cannot be negated.
The range of this spell cannot be modified and
must be measured from the caster, even if an
ability would allow you to measure it from
elsewhere.
