Amaranthine Orb

Amaranthine Orb has a casting value of 6.
If successfully cast, pick 1 point on the battlefield
within 9" of the caster that is visible to them and
draw an imaginary straight line 1mm wide
between that point and the closest part of the
casters base. Roll a dice for each unit that has
models passed across by this line.
On a 2+, that unit suffers D3 mortal wounds.
DEATH units are not affected by this spell.
