Demons, Devils, other Non-Specified Fiends, and Celestials (I believe) can only be killed when in their own repective planes of existence. If a Demon, Devil, other Non-Specified Fiend, or Celestial is killed outside of their respective plane of existence, they will simply crumble to ash and regenerate over a perdiod of time ranging from hours to months in their respective plane of existence. Note:  I may be wrong about Celestials regenerating, but all Fiends work in this way.
