Green Puke

The Weirdnob vomits forth a green river of
searing ectoplasm.
Pick 1 point on the battlefield within 2D6"
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
caster's base. Each unit that has models passed
across by this line suffers D3 mortal wounds.
