Dredbats are a type of bat found in Revendreth. They are created in the same manner as stoneborn but lack their intelligence. Dredbats patrol the skies of Revendreth, alerting their stoneborn brethren to attack intruders, but they are more than capable of killing adversaries by themselves. With the anima drought, the venthyr's dominion over the bats has waned.
- A group of dredbats is called a fright.
