Visions of Death

The abyss reaches out and grants you a vision of an impending death. It speaks to you, "You must make it so." If heeded in the manner of the vision you will gain advantage and add a d8 necrotic damage to the strike. If the target dies you gain 1d8 health back and gain the effects of inspiration. If you fail to kill the creature or it dies by another's hand a schism forms in reality and you take 1d6 Psychic damage.
