Medieval Fantasy RPG Rules (Eternus)

Immortal (Level 101+) If you are proven worthy you become an avatar of your deity and must serve him or her whenever they call. At 100th level you are too powerful for the prime material and are challenged by an avatar of a deity. Challenges can vary from great calls of valor to challenges that require great sacrifice and effort on the part of the recipient. Other times the avatars of the enemies of the deity that aided you in your progression of power are alerted to your presence and issue a challenge of honor. These challenges are called Blood Challenges and are almost always fought to the death.
