Homebrew Giant Bat Species Details

Giant bats, also known as dire bats, were giant bats the size of horses.

Dire bats averaged 200 pounds (91 kilograms) and had leathery wings that stretched 15 feet (4.6 meters) from end to end. Their bodies were covered in shaggy fur.

Dire bats hunted at night and rested during the day. They were stealthy and used echolocation to locate prey. These bats were easy to startle and tended to kill or drive away any other encountered creatures with their bite.

Dire bats flourished in the deepest regions of the Underdark.

Dire bats were favored by the orc god Shargaas. They were used as mounts by members of the Shadovr military and Zhentarim Skymages. Shield dwarves of Oghrann in the Upperdark kept large populations of dire bats to use as mounts as well. In the 15 century DR, giant bats were more commonly known for being the steeds of the Lance Defenders, the army of the dragonborn nation of Tymanthar.

The drow kept dire bats both as objects of gambling and steeds. As the former, dire bats were used like chickens or dogs to fight each other, and the drow bet on the outcome. These fights happened either in the air or on the ground, in the latter case, the animals were specifically crippled. The latter use as steeds was dangerous for the rider and was done only in some drow cities. In that case commoners, which might well include children, were used, so that the damage to a community was negligible, if the rider died.
