Batfolk reach maturity by age 10. Little is known about the further ranges of their age.

Batfolk vary wildly in size; smaller subspecies can range up to about 3 feet, while larger subspecies can grow up to about 7 and a half feet tall. Your size is Small or Medium, chosen upon character creation.

Your base walking speed is 25 feet.

You have a flying speed of 50 feet. To use this speed, you can’t be wearing medium or heavy armor.

Your claws are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal slashing damage equal to 1d4 + your Strength or Dexterity modifier, instead of the bludgeoning damage normal for an unarmed strike.

You can speak, read, and write Common and Chiropteran. Chiropteran is a primarily verbal language comprised of clicks, squeaks, and ultrasonic keening.
