Baleful Scion

You can channel cosmic forces of evil to gain these benefits:

• Grasp of Avarice.

  Once per turn, when you damage a creature you can see within 60 feet of yourself, you can also deal Necrotic damage to it. The Necrotic damage equals 1d6 + your proficiency bonus, and you regain a number of hit points equal to this Necrotic damage dealt. You can use this benefit a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.
