Voracious Maw

Pick 1 enemy unit within 18" of the caster
that is visible to them. That unit suffers D3
mortal wounds. After resolving any damage,
roll a dice. On a 1, 2 or 3, the maw is said to
be satisfied and the spell ends. On a 4+, the
target unit suffers D3 additional mortal
wounds. Keep repeating this process until
the maw is satisfied or the target unit is
destroyed.
