Lasting Life

(Libris Mortis: The Book of the Dead, page 28, DnD 3.5)

[General]

You can shed negative levels with an act of will.

Prerequisite

Endurance, Enduring Life

Benefit

Once per round as a standard action, you can attempt to remove a negative level from yourself by attempting a Will save (DC 10 + 1/2 attacker's HD + attacker's Cha modifi er). If the saving throw succeeds, the negative level goes away. You make a separate saving throw for each negative level you have gained. If the save fails, you retain the negative level, but you can try again next round to remove it.
