The Void type is used at a specific location to summon a Void Bat. Affected by the Power of the Void, this creature becomes more aggressive, attacking anything in its path. The influence of the Void transforms the Bat's nature, making it far more unpredictable and dangerous than ordinary bats. Those who are brave enough to confront and defeat the Void Bat have a chance to obtain rare items, such as Bat Fangs. These items can be used to craft or upgrade equipment.
