The flying nightmares known as Calamity bats are the giant predatory cousins to their normal counterparts. With a wingspan of nine feet, they are a constant threat to the local inhabitants of Netherwarren. Their great wingspan grants them long distance flight and impressive aerial agility, but they are still bat-shaped and not streamlined for high-speed dives. To compensate, they have developed a powerful, high-pitched scream that can distort the air, crack wood, and stun any creature caught in the swarm's path. Their yellow eyes are no stronger than an average bat, and their hearing is sharp enough to hear heartbeats up to a mile away. They are often found in the damp, dark underground caves and abandoned buildings in Netherwarren, making them a lethal threat to adventurers and Netherwarren locals alike.
