Enervative Healing
( Races of Faerun, p. 163)[General]
You can use the life energy of an opponent to heal yourself.
Prerequisite
ability to use enervation as a spell-like ability, Fey'ri,
Benefit
When you use your enervation ability, you may choose to touch an opponent instead of firing a ray, making a melee touch attack to do so. If the target gains negative levels, you heal 5 hit points for every negative level the target gains from this attack as if you had been healed with positive energy.
