Your attempts to banish the souls of those you slay are never wasted, and you gain temporary vigor when you do so.
Prerequisite(s): Angel of death class feature
Benefit: If you declare the use of your angel of death ability and miss with your attack or the target successfully saves against the death attack, your angel of death ability is not wasted and you may attempt to use it again. In addition, when you successfully slay a creature with a death attack imbued by the angel of death ability, you gain temporary hit points equal to 10 + the HD of the creature slain.
