Bloodhunter Initiate 2.0

Studying Hemocraft, you learn one blood curse option of your choice from the Bloodhunter class. Your spellcasting ability for the blood curse is Intelligence, Wisdom, or Charisma (choose when you select this feat). Your hemocraft die for these curses is 1d6.

Also once per day you may cast a Crimson rite: Storms, Frozen, Flame 

Whenever you gain a level, you can replace the blood curse with another one from the Bloodhunter class.
