Vile Transference

Vile Transference has a casting value of 6 and a
range of 9". If successfully cast, pick 1 enemy unit
within range and visible to the caster. Roll a
number of dice equal to that unit's Wounds characteristic. For each 5+, that unit suffers 1
mortal wound and you can heal 1 wound
allocated to the caster.
If the unmodified casting roll for this spell is 9+
and this spell is not unbound, the target suffers 1 mortal wound and you can heal 1 wound
for each 4+ instead of each 5+.
