I get that his driving motivation for this journey is supposed to be "reviving his mother" but...hes reviving random people all the time?
What is stopping him from just slapping his moms soul into some golem?
Like what is the problem? He can just make her a new body at any moment and transfer her.
Hes a walking battlefield spawn beacon but for some reason his mom just has to float around as a shitty dementia ghost.
