So in most games, there’s a caster class and a healer class. The caster is a general mage, usually using the elements to attack enemies from afar. They usually are academics who gained their powers through study. The healer is usually a priest who channels the powers of the gods. The distinction between them is faith vs study.
So here we know that ancient priestly castes were put through academic study of the mysteries of the gods (or demons). They practiced ceremonial Magick. Then there were those folk magicians who focused on nature.
I was thinking, what if a game had a healer witch class which focused on nature? Thus allowing the caster class can take on both priestly and magician based abilities.
