In the minds of players, priests and nuns are usually spellcasting professions dressed in robes, while wearing heavy armor for frontline combat is the business of knights.
However, the priest is a vast hero profession system under the Light Temple, with its branch professions including monks that only males can partake, nuns only females can partake, and priests who focus on prayer. These professions further have advanced forms, such as monks advancing to zealots, nuns advancing to Holy Spear or Holy Sword Sisters, and priests advancing to bishops.
Overall, the more advanced the profession, the closer it gets to the state of being both magical and martial like an angel, and this state facilitates angel possession. After all, a frail body and weak magic power cannot support angel possession. To advance to the high-level profession of Holy Spear Sister, the minimum requirement is to have a Master-level main profession and Light Magic, along with enough reputation.
