Solar Flare

Casting value of {8}. If successfully cast, pick a
point on the battlefield within 10" of the caster
and visible to them. If there is an endless spell at
that point, it is dispelled, and if there is a unit at
that point, roll a number of dice equal to the
number of models in that unit. For each 6+, that
unit suffers 1 mortal wound. In addition, until
your next hero phase, subtract 2 from casting, dispelling and unbinding rolls for
WIZARDS within 12" of that point.
