The bodies of fire bats roughly had the shape of a normal bat, though they were completely wreathed in continuously burning, red flames. Their bodies were 2 feet (0.61 meters) in length and had wingspans that measured 4 feet (1.2 meters). Their skin was tough and leathery, with a red-tinge. The toughness of their skin made even their relatively thin wings difficult to cut or pierce through. Their heads had small mouths full of razor-sharp teeth.
Fire bats had a very limited level intelligence, surprisingly greater than that of a mundane bat, and were remarkably cunning when engaging in combat. Being more adapted to flying, they were quite clumsy when walking, walking in a hopping manner.
Fire bats had a fear of water and a fondness for shiny, sparkling objects. Such objects were typically gems and jewelry. They especially loved carnelians, jacinths, and rubies. They would store such objects within their lairs.
Much like mundane bats, they possessed blindsight and navigated by means of echolocation, emitting high-frequency sound inaudible to most creatures that bounced off walls. Through this they were capable of discerning objects and creatures from up to 120 feet (37 meters) away. They also had darkvision out to 60 feet (18 meters). The vision provided by their eyes was quite weak and only extended out to 10 feet (3 meters).
Due to their elemental nature, fire bats had regenerative abilities and were impervious to harm from poisons, fire or fire-based spells, and were unaffected by the spell sleep. They also could not be stunned or paralyzed. However, it also meant that their bodies were especially vulnerable to harm from severe cold or cold-based spells.
They were incapable of entering any body of water, as well as any liquid that wasn't flammable. Though they could effortlessly glide through lava and magma. It took over 10 gal (0.038 m³) to extinguish their flames. This preventing them from flying, though did not harm them in any way.
Fire bats reproduced asexually by a process of fission, splitting themselves into two when properly full of food. When food in an area was very plentiful they could reproduce at a rapid rate. However, once a bat reproduced they could not do so again for up to a year.
Prior to the Time of Troubles, their bodies would become engulfed in flames upon being killed and transported back to their home plane as small balls of fire that eventually regained their true form. This would occur even on their home plane. Following this period, their bodies simply sizzled out gradually upon being killed.
Fire bats typically attacked with other members of their colony, hunting in packs. When attacking groups of creatures they would divide their attention among all targets evenly, though they never fought groups larger than their own. If their numbers dwindled during a fight, they were likely to flee and recuperate, planning to attack the same group at a later time if possible.
Fire bats fought by biting at victims, draining their blood while simultaneously imparting damaging fire upon them. Even hitting them with naturally weaponry put one at danger of catching on fire. They tried to swoop down at their enemies, while also doing their best to avoid any opportunity attacks.
Fire bats often attached themselves to a single victim, seeking to eat away at their bodies until their hunger was satiated. They would then attempt to flee the battle in order to digest their meal.
These creatures typically laired within rocky, cave-like areas that had many exits but only one noticeable, large entrance. Unlike mundane bats, who tended to be found in darkness, fire bats preferred to live within well-lit areas.
On occasion they would dwell within the body of a fire elemental and feed upon the creatures that they consumed.
Fire bats could occasionally be found on the Prime Material. There they were primarily found in hot locations such as hot springs and volcanoes. Such locations included the volcanic caverns of Mount Hotenow, the volcanic caverns of the Underdark, and the Chaos Wastes of the Deep.
They had good relationships with fire elementals and were never known to attack them. Though many denizens of their native plane hunted them down in order to control their population from overgrowing. Those who hunted them included efreeti and salamanders.
Rumors & Legends
Prior to the Time of Troubles, many were uncertain as to how fire bats made their way to the Prime Material plane. Some speculated that on rare occasions they had hitched a ride with conjured fire elementals. Specifically those conjured by priests and wizards.
