Fang of the Withering Hunt

This weapon grants a +1 bonus to attack and damage rolls. This blade also deals an additional 1d4 necrotic damage on hit. If you reduce a creature to 0 HP, you gain temporary hit points equal to your Wisdom modifier + your proficiency bonus. This ability can be used twice per long rest.

"The fangs of a predator tear through flesh, but this blade hunts deeper—into the soul. Those who fall to it feel their strength slip away, stolen by the darkness that clings to the steel."
