These bats are unable to unload with the same fury and damage. They are, however, able to enfeeble their attackers, lowering a party's attacks and defense. Also unlike the trios, they are able to absorb both HP and MP from opponents, often prolonging the battle.
When defeated, these bats will typically drop wings and fangs, and some will drop blood or treasure chest keys.
