Godhunter

Fighter, Ranger, or Rogue Level 16

Background
    Epic Destiny
This feature can be taken twice, with additional effects being granted on the second time it is taken.   First Level Features
Deific Agony: When you score a critical hit against a creature whose CR is greater than your level, the creature takes a −5 penalty to saving throws and cannot regain hit points or recharge any powers until the end of your next turn.   Second Level Features
Blasphemous Recovery: Once per day, when you are hit by an attack from a creature whose CR is greather than your level, you can choose to treat that attack as a miss and then regain half your hit points.   Immortality
You met your utmost challenge, and look who’s dead and who isn’t. The proof is in the grave. Among those that have a similar mortal origin, you are the greatest slayer in the universe. Maybe a god or two has skills that compare. Maybe. Sticking around to stir up the cosmos isn’t a bad idea. Powerful mortals, deities, demon lords, and primordials can get complacent or uppity. The worst rest in their own realms in smug satisfaction, and either cease doing what they should do or start doing something they shouldn’t. No one rests easy with you nearby. Mortal terror has a way of inspiring decisive change, and you have a pointed way of rousing just such a fear. It’s not that you need to threaten anyone in particular. It could just be made known that you have a particular agenda. Working as a free agent, you leave no entity safe from the prospect of your lethal prompting. Even a little prodding is bound to be a boon to progress. You could be just the wild card the world needs to keep power in the right balance and affairs moving along smoothly.
