I Will Return

FEAT 9

Your special connection to death and rebirth allows you to sense when it's your time to enter the Great Beyond, and now isn't the time. You gain +2 status bonus to saving throws against death effects. You gain the Diehard feat. The first time each day that you lose the Dying condition, you do not increase your Wounded condition.
