Here is an interesting situation.
A paladin agrees to a one on one duel to the death with a certain evil captain of a witch's guard. the paladin after a valiant effort falls unconscious at the captain's feet. With no request or previous agreement the paladin's comrade (a Priest) runs into combat and cures the paladin to 4 hp. What should the paladin's next action be in keeping with the paladin's code? what action(s) would lead him to having to atone? There where no preset conditions mentioned before the duel except that it was to the death.
