Devour the Soul (3.5e Feat)
From D&D Wiki
Devour the Soul [Fiend]
As a fiend, you gain nourishment from devouring souls.
Prerequisite: Must have one level of a Fiend class
Benefit: Each time a soul is consumed (either a receptacle or petitioner), you regain HPs equal to 10 times its CR, and heal ability damage or drain equal to its CR. Souls eaten in this fashion cannot be restored from the dead until you are killed.
