[SPELL] Amaranthine Orb

Amaranthine Orb has a casting value of 7. If cast,
pick a point on the battlefield within 12" of the
caster and draw an imaginary straight line 1mm
wide between that point and the closest part of
the caster. Roll a dice for each unit (friend or foe,
apart from the caster) that has any models beneath
this line. On a 4+ that unit suffers D6 mortal wounds.
