A powerful person doesn't mean a skillful person or someone with a powerful divine ability, it means all those things and most importantly, it means having feats It is that powerful person that must carry the crown. They are to command their group from afar where they are safe so that the golems don't focus on them. This person will also be very difficult to ambush and they will be able to respawn if they are killed.
A group that lacks numbers will be overwhelmed easily and a group that lacks a powerful leader can be eliminated by someone who has both powerful skills and divine abilities and can also respawn. The respawn became a cheat for those with feats. It granted them the chance to return after death and fight again. Powerful individuals with feats have no problem acquiring a crown but they need a group to maintain the possession of the crown.
