"I had believed my new assistant was the noisiest creature in the world, but that was before I discovered the shrieking terror. The batlike monstrosity produces the most earsplitting racket imaginable and, furthermore, managed to make my assistant scream even louder! I think my headache will last for weeks now..."— Abd al-Hazir(src)
Terror Bats are larger than the Vile Bats, and may attack from a distance with piercing sonic waves. When needed, they can pick up nearby Boggits, bite them, and turn them into Bogan Brutes. The process can go the other way as well. In addition, Terror Bats may perform a 'gliding charge', dashing forward and damaging and briefly Stunning all enemies in their path.
