The Hierophant may deal little damage in the beginning, but as his allies die he only grows stronger due to his Cherished. If the enemy were to try to kill him, his allies will take the damage for him, making him gain large amounts of power. This increased attack translates into increased healing due to Drain Life. When he dies, he will siphon health from an enemy hero to his summoner thanks to his Blood Tax.
