Vile Transference

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 allocated to the caster for each 4+ instead of each 5+.
