According to the myths of the Dark Six, the Keeper covets the souls of the living, and his servants sometimes possess the ability to steal away a creature's soul. These myths are most commonly associated with the Keeper's fang dagger, and Dark Petitioner rogues (presented at the end of this chapter) gain a similar ability at 17th level. However, powerful fiends in service of the Keeper's ideals--or even the enigmatic god himself--might bestow loyal followers or fated individuals with the following blessing. Such supernatural gifts are discussed in chapter 7 of the Dungeon Master's Guide
Blessing of the Fang
When you touch a creature that has been reduced to 0 hit points or killed within the last minute, you can choose to kill it (if it isn't already dead) and remove its soul. A creature whose soul has been removed in this way can be restored to life only by a wish spell.
