Part of why I wanted outside fate rather than fatebound. It is the more interesting road since it is less used. (The only time I've ever really encountered it as a core concept was in Kingdoms of Amalur: Reckoning, which I wish took off as a game series since it was really fun)

Anyway, the undying sage sounds like a good idea. By slow regen, what do you mean? Is it like D&D troll regen where they can reattach limbs and heal fast enough not to keel over but not fast enough to ignore the dangers of damage?
