Inevitably Tom is going to need to kill a demon (true death). How does one demon kill another? I know Lilith remarked several times on killing demons (well Tizzy) and it sounded like there are two ways. One where it sounded like the demon is absorbed into the stronger demon and the other where it’s simply dissolved. If it isn’t too much of a spoiler, can you explain it?
Also, in the fight at the end of volume I, the priests cast a black cloud spell on Tom which severely hurt him and caused him to start bleeding out of his pores (who knew demons had them :p). Were they attempting the CoD? If so why didn’t it instantly kill Tom like with the level 3 demon?
