These enemies have slightly higher stats than the Temple Guards, and although they can't use physical attacks, it doesn't mean they can't attack, as they can use the magical attack Divine Punishment, and can also increase the attack and defense of their allies with the Blessing skill. Aside of this, they also have access to the Healing skill, meaning that they can turn other enemies into threats, aside of prolonging the battle needlessly, so take care of them first.
As a side note, due to the location in which they appear, these enemies can only be encountered in Aurica's Route.
