Fate-changers can choose hosts, and what do they do to them? Anything they wish to. But Nidwarde would just use the hosts as a way to drain their energy for his own benefits. The reason why Fate-changers, mainly Nidwarde, drain their host of anything is to ensure their own energy with the universe. Because since they are basically spirits with the status of a God, they can easily fall victim to the void. Using this energy keeps them from breaking out of reality. This is why Nidwarde is manipulative and hostile towards his hosts, especially to those who remind him of her past self. This is why Edwardin suffered the most, compared to the past hosts. If Edwardin succeeds in killing the host through fate, which is hard to do because when you're the host, they are unable to write your fate easily. Edwardin was a hard one to kill off through other means due to his will to live for his friends. That's why Nidwarde had to make Edwardin be the fault of his death.

And when Fate-changers are successful in killing their hosts, they gain much more energy, power, and stability by the universe. Fate-changers are considered very powerful, which is why you shouldn't mess with one if you are able to access their realm of reality. Fate-changers know all of anything, and they know what's a lie and what's truth. Let's get into the pros and cons of this title.
