Immortality (3.5e Feat)
From D&D Wiki
Prerequisite: , Purge Metabolism, Vitality
Benefit: You are immune to poisons and diseases. Furthermore, your power continually purges your body of the harmful physical effects of age. You do not physically age beyond the midpoint of the "adult" age category for your race (Halfway between reaching adulthood and the onset of middle age: for humans, this corresponds to an age of 25 years). If subjected to unnatural aging (And if you survive it), or if you're older when you gain this power, you will return to your natural age (or the midpoint of "adult", whichever is lower) at the rate of one year of age for each day that passes.
