Touch of Vampire (3.5e Feat)
From D&D Wiki
Touch of Vampire [Necromantic]
You can use your Charnel Touch to heal yourself
Prerequisite: Able to use Charnel Touch or Withering Touch, Base attack bonus +2
Benefit: You can turn your Charnel Touch or Withering Touch to "Touch of Vampire". You make a melee touch attack against a living foe that deals 1d8 points of damage, +1 per four class levels, and heal yourself the same number of damage you deal. And if you use it on undead, it heals both of you restoring 1 hit point per touch, +1 per two class levels. You can use the spectral hand spell to deliver this attack from a distance.
