For example if a wyrm with 2 heads ends up as zombie with 1 head 1 helmet is lost.
Wait... this means you can have a zombie as a pretender god? Or, does this make it so that you can then call god your pretender (with the new lower magical paths) so that you can pseudo-duplicate the pretender's magic?
Oh, sorry, the Wyrm was just the first thing that came to my mind having two heads. Don't know if a god can become a zombie.
Probably should have sticked to Machaka sorcerers (become a spider with only misc slots when killed).
