Priests are often called ‘divine spellcasters’, they believe that their mage gift is a gift of their belief and channel an aspect of their divinity through their powers. Their abilities are often tailored to match aspects of their worshipped greater power. Much arguing about if they are really special compared to other sorcerers exists, but functionally they seem identical.
Most Priests have healing and defensive abilities, but some have offensive skills as well. Training wise they are much like their sorcerer brethren, but are usually trained through a church.
