This bat craves the blood of the living and is every mage's bane because it uses Magic Thirst to drain MP. Its Venomous Fangs attack is also a threat.
The Blood Bat is an enemy in Bravely Default. Its Venomous Fangs attack can inflict Poison, and its Magic Thirst attack drains MP, but its damage is not too great a concern. It is weak to Wind magic, and a Thief with a bow will make short work of one.
