Precepts Guard can cast spells like Bio and Demi and can drain the party's HP and MP. It can also inflict the party with Slow, and cause Instant Death. To defeat this fiend, the girls need to attack it with their strongest attacks and magic. Precepts Guard is weak to Holy, so attacks like a Warrior's Excalibur does heavy damage.
