Priests are known for their compassion, empathy, and healing abilities. In fact, they are the only spellcasters that get bonuses with healing spells. As spellcasters, their school of magic is Divinity. They are do their best to ensure every party member is happy and healthy. While they generally avoid attacking hostile enemies, they will do so in self-preservation circumstances. Finally, Priests are the only vocation that pray to the gods, which sometimes results in divine favor or other tremendous benefits (although it's rare to have prayers answered).
