Jergal's Pact( Lost Empires of Faerûn, p. 8)
You have made a bargain with Jergal, seneschal to the god of death. Although Myrkul, Cyric, and most recently Kelemvor have all served as the god of death, each has honored these pacts.
You gain a +2 bonus on saves to resist gaining negative levels or to remove them. If the effect that bestowed a negative level allows a Fortitude save to remove it, you can choose to attempt it after only 1 hour. (You can also choose to wait the usual amount of time before attempting the save).
You make saving throws to remove negative levels 24 hours after gaining them.
