Source death knell

Increase the spell's range to close (25 feet + 5 feet per 2 caster levels). Increase the temporary hp gained from the spell to 2d8 and the enhancement bonuses to Strength to +4, and gain a +4 enhancement bonus to Dexterity.

Augmented (3rd): If you expend two uses of mythic power, the casting time decreases to 1 immediate action, and you may target a creature that you killed on your last turn as if it were still alive; the dead target gets no save.
