Sins of the Father
Nephalem of Healing
Half Angelic Child
Like all Nephalem, Seth has a single angelic skill vastly superior to anyone but the most powerful in the Angelic host. His regenerative abilities are so potent that he continues to heal at an alarming rate even in the presence of Angelic Wards. More than likely, Seth cannot be killed and his regenerative ability may be so advanced he doesn’t even age.
As the prophecy dictates, Seth met the Prophet the day of his 18th birthday a few days after his capture by demons.
