Large carnivorous bat with 15-foot wingspan

These are giant versions of carnivorous ordinary bats. Their bodies grow up to 3-ft long, and they can have wingspans of up to 6-ft. Highly manoeuvrable, users of missile weapons will suffer a -3 "to hit" penalty unless the attacker's dexterity is 13 or higher. They must land on their intended victims to attack. There is a 1% chance that those so bitten will contract rabies, or some similar blood-borne infection.
