Soul Stealer

If successfully cast, pick 1 enemy unit within range and visible to the caster. That unit suffers D3 mortal wounds. If the unmodified casting roll for this spell is 9+ and this spell is not unbound, that unit suffers D6 mortal wounds instead of D3. You can heal up to 1 wound that has been allocated to the caster for each mortal wound caused by this spell that is not negated.
